Guide to the readings

The time of birth is not known, so this chart is worked out for noon. The lagna and houses are not shown, and the Moon (and so the dasha dates) can be off by up to 6 degrees.

These are facts from the chart, not a reading. The colours: green exalted, blue own sign, red debilitated, orange combust, violet retrograde, indigo vargottama.

Parashari rule: every planet looks at the 7th from where it stands; Mars also at the 4th and 8th, Jupiter at the 5th and 9th, Saturn at the 3rd and 10th. Rahu and Ketu are shown only as aspected, because the texts disagree about their own aspects.

Counted by sign, the Vedic way: same sign, 7th (opposition), 5th and 9th (trine), 4th and 10th (square), 3rd and 11th (sextile). "Tight" means within 5 degrees of the exact angle. Sorted closest first. Rahu and Ketu are always opposite each other and are left out of the pairs.

Values in shashtiamsas (60 make a rupa). Only the parts that can be worked out without school-dependent choices are shown. Kala bala (temporal) and Cheshta bala (motional) are not computed, so no total or rupa figure is given and these numbers should not be compared with the usual minimum requirements. Sthana, Dig and the natural value were checked against PyJHora on 40 charts (moolatrikona counted by sign for that check; the page counts it within its degree limits). Drik bala (aspectual) is not yet computed. Green marks the strongest planet by Sthana bala.

Sarvashtakavarga (SAV) by sign, shown from the lagna. 337 points in all; 28 is the average for a sign, so a sign above 28 is better supported and one below about 25 is thin.

Bhinnashtakavarga (BAV): each planet's own points in each sign (8 at most). 4 or more is the classical mark of a favourable transit through that sign.

The contribution tables are the classical ones and the result matches DashaFlow on 80 random placements. The career rules use these points to mark Jupiter and Saturn passages through the 10th house, the 10th lord's sign and the 10th from the Moon as supported (4 or more of 8).

Every combination below is found by a written rule from the birth chart, with no AI. The rules follow the Parashari texts as they are commonly taught from Brihat Parashara Hora Shastra; each item says whether it is classical or later tradition (Kala Sarpa, Guru Chandal, Grahan, Shrapit, Angarak, Vish and Pitru dosha are not in the Parashari texts, but are widely used). The tag is my best classification and gives no chapter numbers, so have an astrologer confirm any rule you depend on. Where schools differ, the rule used is written in the item. A yoga or dosha describes the chart; it is not a prediction, it says nothing certain about what happens, and nothing here feeds the career readings. Strength: full, partial (a link by aspect only, a combust or weak planet, or a looser match), weak, or reduced or cancelled where the texts give a cancellation. When it is live: the periods in which the planets that form it run, as Mahadasha, or as an Antardasha where both lords are among them; tap a period to open it in the Vimshottari dasha table.

The Natal Yogas and Doshas section lists what the birth chart itself forms. The Gochar section lists the gochar (transit) yogas and doshas, those that form in the sky, with the dates: either among the planets themselves (the same for everyone) or against your birth chart. Only the slow planets are used (Jupiter, Saturn, Mars, Rahu and Ketu), because the Sun, Moon, Mercury and Venus change sign too quickly for a sign-level yoga to mean much, so a transit Kala Sarpa, a Moon-based Vish and eclipse seasons are not listed. Planets are counted in the same sign, not by degree, and dates are found to the hour. Saturn over the birth Moon is the middle of Sade Sati, whose full dates are in the Transits section. These describe the sky against the chart; they are not predictions, and nothing there feeds the career readings. If the time of birth is not known, the birth Moon (used by two of these) may be in the wrong sign.

How a transiting planet is weighed. Every reading that uses the sky now weighs a planet in the same way (README #596).

Strength in its sign. In the order of Saravali (chapter 5, verses 25 and 26), the good a planet gives is greatest when it is exalted, then in its Mooltrikona, its own sign, a friend's sign, little in an enemy's and none in its fall; the harm runs the other way. The monthly and yearly readings therefore scale a planet's good results by one plus its points and its bad results by one minus its points, with the points running from +0.5 (exalted) to −0.5 (debilitated). The figures are a judgement on the book's order.

Backward motion. Mars, Mercury, Jupiter, Venus and Saturn gain the greatest motional strength when they move backward (BPHS, Brihat Jataka, Saravali, Sarvartha Chintamani and Raman all say so), and a strong planet gives more of what it gives, helping or straining. Its results are therefore raised by half. No book gives a figure for transits, so the half is a judgement. Rahu and Ketu are always backward and the Sun and Moon never, so they carry no such weight. Exalted and backward at once is left as it is, because the books disagree (Brihat Jataka counts it stronger, Saravali says it gives no results).

Where it is used. The monthly and yearly readings (the weight of each stretch); the layers S8 (a strong slow planet) and S9 (a backward slow planet) in Peaks and dips, the full reading, the periods tables and every score built from the layers; the career opportunity strength (its own strength factor was already there; backward motion is new); the plain reading in 22A; and the transit table, whose last column shows the factors for each planet. The Vimshottari dasha table also shows when in its period each Mahadasha and Antardasha lord gives its results (BPHS volume 2, chapter 47: by the drekkana of the lord, reversed for a planet that was backward at birth, and for Rahu and Ketu).

How far to trust it. These weights describe the chart. On marriage and child-birth dates the rules of the books read in this work (README #586 to #589) did not mark the dates better than chance.

The chart is read three times at once: with the houses counted from the rising sign (Lagna), from the Moon and from the Sun. Each ring is the same twelve signs, only the starting point changes, so a planet can be in the 10th house from the Lagna and the 2nd from the Moon. An area of life that looks good from all three starting points is read as more dependable than one that looks good from only one.

The row marked for the year is the house of the year of age you are living: the first year of life is house 1, the second house 2, and so on, back to house 1 in the thirteenth year. It is the same house number in all three rings. The count of kind and hard planets is plain, not corrected for how strong each planet is. This follows the layout taught in the classical texts; it was tested against marriage and child-birth dates and picked out no year better than chance, so treat it as a way of looking at the chart, not a way of timing events.

Each year of life starts again at the birthday, defined in the Tajika way: not by the calendar date but by the moment the Sun returns to the exact degree it held at birth. A chart is drawn for that moment at the birthplace and read for the year ahead. Because the sidereal year is a little longer than the calendar year, the moment drifts later by about a quarter of a day each year, so it falls on a different date and hour than the birth.

The Muntha is the birth rising sign moved one sign for each completed year; the house it falls in, in the yearly chart, shows where the year's attention goes. The Lord of the Year shown here is simplified: of the lord of the Muntha, the lord of the birth rising sign and the lord of the yearly rising sign, the one with the best Shadbala ratio. The classical rule has five office-holders and looks at their aspect to the yearly rising sign; Mudda dasha, Tajika yogas and sahams are not built yet. It was tested against marriage and child-birth dates and picked out no year better than chance for marriage, child birth or a career step. Read it as a way of looking at the year, not of dating events.

Upagrahas are the "shadow" points of the old books. Five come from the Sun alone and need no time of day: Dhuma, Vyatipata, Parivesha, Indrachapa and Upaketu (together the Aprakasha grahas). The others come from the time of birth: the day, from sunrise to sunset (or the night, from sunset to the next sunrise), is cut into eight equal parts ruled by the planets in weekday order; the sign rising in the part ruled by Saturn gives Gulika (at the start of the part) and Mandi (at its middle), and the parts of the Sun, Mars, Mercury and Jupiter give Kaala, Mrityu, Artha Praharaka and Yama Ghantaka. The books disagree on whether Gulika or Mandi is at the start; this page follows Jagannatha Hora.

Pranapada lagna is the Sun moved on by the time since sunrise; Kunda lagna is the Lagna times 81; Bhrigu bindu is the midpoint of the Moon and Rahu. They are calculated points, shown for reference. They feed no reading.

Each sphuta is a sum or multiple of longitudes: Tri sphuta is the Moon plus the Lagna plus Gulika, Chatur adds the Sun, Pancha adds Rahu, Prana is five times the Lagna plus Gulika, Deha is eight times the Moon plus Gulika, Mrityu is seven times Gulika plus the Sun, Sookshma tri sphuta is the sum of those three, and so on. Prasna Marga reads the sign each one falls in for the matter it is named for. Here they are only calculated; no reading uses them.

A saham (a "sensitive point" of the Tajika, yearly-chart tradition) is found with a formula A − B + C: take the distance from B to A going forward and lay it off from C. If C is not between B and A, 30 degrees are added. For most sahams the two planets are swapped for a birth at night. There are 36, each for a matter such as marriage (Vivaha), children (Putra), work (Karma) or money (Artha). They are shown here as the traditions give them; they were not tested against real events and feed no reading.

The Arudha of a house is how it appears to the world: count from the house to its lord and the same distance again. The Graha arudha is the same for a planet, counted from the planet to the sign it owns. Surya and Chandra arudhas do the same for the twelve houses counted from the Sun and from the Moon instead of the Lagna. Where a planet owns two signs, the stronger sign by the Jaimini rules is used. The book (BPHS chapter 29) says the ten-sign exception used for the houses does not apply to the planets; the programs in use apply it to them too. The table gives both: the first row with the exception, the second as the book has it (a sign that differs is in bold).

In the whole-sign chart every planet in a sign belongs to that house. Bhava chalita instead centres each house on its cusp, so a planet near the edge of a sign may move to the next or previous house. The equal method takes the Lagna degree as the middle of every house; Sripati takes the Lagna and the midheaven as the middle of the 1st and 10th houses and shares out the rest equally.

The panchang at birth gives the weekday, tithi, star, yoga and karana. This adds the parts of the day and the calendar: Rahu Kalam, Yamaganda and Gulika Kalam are each one eighth of the day (sunrise to sunset), which eighth depends on the weekday; Abhijit muhurta is the middle fifteenth of the day and is counted auspicious; Brahma muhurta is the hour or so before sunrise; Durmuhurtam is a short inauspicious stretch read from a weekday table. The lunar month comes in two forms: the Amanta month ends at the new moon and the Purnimanta month at the full moon, so the dark half of the month has a different name in the two. A month in which the Sun does not change sign is the extra (adhika) month. The yogas of the day (Amrita siddha, Sarvartha siddha, Mrityu, Daghda, Yamaghata, Utpata) are read from the weekday and the Moon's star. Karaka tithi is the tithi counted between two significators instead of the Sun and Moon. They are traditional markers, shown for reference; they feed no reading.

The Varnada lagna is a Jaimini point that shows the social standing and the means by which a person is known. It is found from the Lagna and the Hora lagna (the Lagna that moves on at a sign every half hour from sunrise): each is counted from Aries if its sign is odd, or backwards from Pisces if even; the two counts are added when both are odd or both even, and subtracted otherwise, and the result is counted forward from Aries (odd) or backward from Pisces (even). The same is done for every house by moving the Lagna and the Hora lagna to that house. Several authors count slightly differently; two ways are shown.

Vimshottari (120 years, the one the rest of the page uses) is only one of many dasha systems in the old books. This section shows several others, all worked from the same birth chart.

By the Moon's star. Like Vimshottari, these start from the star the Moon was in at birth and run a cycle of planets with fixed years: Ashtottari (108 years), Shodasottari (116), Dwadasottari (112), Panchottari (105), Satabdika (100), Chaturasiti sama (84), Dwisaptati sama (72), Shastihayani (60), Shattrimsa sama (36) and Yogini (36). Most are conditional: the books say to use them only when the chart has a particular feature (for example Ashtottari when Rahu stands in a kendra or trikona from the Lagna lord), and the section says whether yours does. Tribhagi Udu is Vimshottari with every period a third as long, run three times round.

From birth. Naisargika (the natural dasha) is the same for everyone: Moon 1 year, Mars 2, Mercury 9, Venus 20, Jupiter 18, Sun 20, Saturn 50, Lagna 12. Buddhi Gati (Sanjay Rath) takes the planets house by house from the 4th and sets each period by how far the planet is from the Lagna.

Sign dashas. Here each period is a sign, not a planet. In Narayana, Sudasa and Moola the length of a sign's period is how far the lord of the sign is from it; Shoola and the Navamsa dasha give every sign 9 years (two Shoolas are offered: one from the Lagna or its 7th, one as BPHS gives it, from the 2nd or 8th). In the Ashtottari and Shastihayani the star Abhijit counts as a 28th star, as BPHS says. Narayana can also be worked on a divisional chart. Where a sign has two lords (Scorpio, Aquarius with the nodes) the Jaimini rules pick the stronger. These have not been tested against real events and feed no reading.

Shadbala looks at a planet in the birth chart. Vimsopaka bala looks at it in the divisional charts as well: the more of the divisions it stands well in, and the more important the division, the higher its mark out of 20. A planet in a sign it owns gets the full mark for that division; otherwise the mark depends on how it stands to the lord of the sign (a close friend, friend, neutral, enemy or close enemy). The marks of the divisions are added by their weights (for example the Navamsa 5 of 20 in Shadvarga). Four sets of divisions are used: 6, 7, 10 and 16.

Vaiseshikamsa counts how many divisions the planet is in its own, Mooltrikona or exalted sign, and the books give a name to each count (Parijatamsa for 2 in the ten-division set, Uttamamsa for 3, and so on up to Sridhamamsa for 10). Not tested against real events; these feed no reading. Other programs (Jagannatha Hora and the services built on it) use another form of the Hora chart, the Parashara one, and so show different numbers for the Moon and a few other planets; here the Hora is the Sun-and-Moon one the book gives, and with the other form the Shadvarga, Dasavarga and Shodasavarga numbers come out the same as theirs.

The Rashmi (rays) of a planet are a measure used in the Rashmi dasha and some books on strength. They run from about 2 to 14. The Uccha rashmi grows as the planet moves away from its deep debilitation point; the Cheshta rashmi comes from its motion; the Subha rashmi is a quarter of the two together.

In the usual aspect rules a planet either aspects a sign or not. Sphuta drishti ("exact aspect") works out how strong the aspect is from the exact angle between two points, in virupas (60 is a full aspect): below 30 degrees nothing, rising through 60 degrees, 90 degrees and 120 degrees to the full aspect at 180, then falling away; Mars, Jupiter and Saturn add their special aspects. This is the aspect used inside Shadbala (Drik bala) and Bhava bala.

Bhava bala is the strength of each of the twelve houses. Here it is the sum of three things: the Shadbala of the lord of the house; the Dig bala (a house is strongest in the direction natural to the kind of sign in its middle: human signs in the 1st, water signs in the 4th, four-footed signs in the 10th and insect signs in the 7th); and the Drishti bala (the aspects of the benefic planets on the middle of the house less the aspects of the malefic ones). The books also add a Kala bala of the house, which is not included. A house with 7 rupas or more is counted as strong. These feed no reading.

"Pravesh" means entry: the chart of the moment a cycle starts again. Tithi pravesh is the moment in the year when the Moon stands the same distance from the Sun as at birth, in the same lunar month: the lunar birthday, and the exact moment of it. Nakshatra pravesh is the Moon coming back to the very degree it had at birth, about every 27 days. Dasha pravesh is the chart of the sky at the moment a Vimshottari period (Mahadasha, Antardasha or Pratyantar) begins. Each is drawn for the birthplace. Traditions read each chart for the period it opens, in the way the yearly chart (Varshaphal) is read for the year. They are shown for reference and feed no reading.

These are dashas that fit inside one year of life, starting at the moment of the Varshaphal. Patyayini puts the Lagna and the seven planets of the year chart in order of their degrees inside their signs; the gaps between neighbouring degrees divide the year in proportion, so a planet with a long gap before it rules a long stretch. Mudda (the Varsha Vimshottari) squeezes the 120 years of Vimshottari into 360 days: Sun 18, Moon 30, Mars 21, Rahu 54, Jupiter 48, Saturn 57, Mercury 51, Ketu 21 and Venus 60 days, starting with the lord of the birth star moved on by the age in whole years. They are shown as the traditions give them; they have not been tested and feed no reading.

A muhurta is a chosen time to begin something. The two parts that depend only on the person are the Tara bala and the Chandra bala. For Tara bala the stars are counted from the birth star in cycles of nine: Janma (birth, middling), Sampat (wealth, good), Vipat (danger, bad), Kshema (wellbeing, good), Pratyari (obstacle, bad), Sadhana (achievement, good), Naidhana (also called Vadha, bad), Mitra (friend, good) and Parama mitra (best friend, good). The day's Moon passes through one or two stars; each stretch is shown with its tara. Chandra bala is the Moon's sign counted from the birth Moon: the 1st, 3rd, 6th, 7th, 10th and 11th are good. A stretch where both are good is marked. A full muhurta also weighs the weekday, tithi, rising sign and many more things, which are not used here.

The Mahadashas of the chart are drawn as a coloured strip along the years of life, with the dated events you have recorded marked on it as dark ticks and today as a red line, so a cluster of events can be seen against the periods. The list below gives the Maha, Antar and Pratyantar running at the date of each event, and a tap on an event opens a window with the sky of that day (purple) laid over the birth chart (black). It is a way of looking at your own events against the dasha; it does not say anything the dashas have been shown to predict.

Astrocartography asks: at the moment of birth, over which places on the Earth was each planet exactly on an angle of the sky? For each planet four lines are drawn. The MC line runs north to south through the places where the planet was highest in the sky; the IC line is the opposite meridian, where it was lowest. The Ascendant line is the curve where it was just rising and the Descendant line where it was just setting. Moving to or living near a line is said to bring that planet's themes into the foreground in that place: the tradition reads the Sun line as visibility, the Moon line as home and feeling, and so on; this app does not give such readings. The lines are the planets' true positions in the sky on the day, so the choice of ayanamsa does not move them. The table lists the lines passing within 400 km of the birthplace and of the largest cities.

The evidence windows below count yes or no layers. This section weighs instead, the way an astrologer judges how strong a period is. Each month gets a strength from 0 to 100 in two parts. Dasha (up to 60): for each running level (Mahadasha 3, Antardasha 4, Pratyantar 2, Sukshma 1, out of 10), how much that lord matters to the career (the 10th lord or a planet in the 10th matters most), times how strong the planet is (its dignity, friendship, aspects and company, placement, strength and ashtakavarga points together), times how well it gets on with the level above it (natural friend, neutral or enemy, and whether the two stand 6th or 8th from each other). Gochar (up to 40): Jupiter, Saturn, Mars and the nodes on the 10th house, the 10th lord's sign, the 10th from the Moon, the 11th, 6th and 2nd, each times how strong the transiting planet is in that sign (dignity, friendship with the sign's lord, ashtakavarga points) and its natal condition, with a bonus when Jupiter and Saturn are on the same point. The weights are an astrologer's judgement, not fitted to anyone's life, and the numbers are not probabilities. The evidence windows are not changed. This does not say whether anyone is in a job, and it uses nothing recorded. A hypothesis, not yet proved against real lives.

The strength shown for the month is the mean of the 5th, 15th and 25th; the breakdown is the 15th. Click a month in the strip or the grid to read another.

Astrology is best used to see the peaks and dips of a working life: stretches where the chart is most active, when it is worth giving your best shot or being ready, and stretches to keep quiet. It does not promise a job change or a promotion in any month: people, the market and personal choices decide that. It is read only for working age (18 to 70) from the layers, taking the busier of the two sets (starting work and leaving work), and each month is read on the 15th. The mark is taken from YOUR OWN months and chosen by data: on recorded job changes the events gather in the top 20% of a person's months by layers on (ties by strength), so those months carry P, and every other month is blank. There is no separate busy or quiet label, because on the same events a busy band added nothing and the quietest months held job changes as often as chance. (Before, fixed marks gave P, B and Q, and because the larger of two counts is taken half of all months read busy or peak.) A P month is a more active one and not a prediction: on 38 recorded job changes of four people the top 20% held 12 against 7.6 expected (a little over one and a half times, not yet a firm result), and on thousands of dated marriages the layers have not been shown to pick events better than chance.

Months are ranked first by the layers on, then by the strength. The strength counts only when two months have the same number of layers, so a month with more layers is never ranked below one with fewer. The ranges are worked out from your own months, so they differ from chart to chart.

Three readings of the same chart. Career change activity is the peaks and dips from the layers: how likely a change is (joining, leaving, a new role). It does not measure whether someone has a job: a person who stays in one job for years looks quiet on it while working and earning every month. Earned income is money from work, read the same way as the career strength (0 to 100) but on the houses a salary comes from: the 11th (gains), the 10th (work) and the 6th (service) and their lords count most, the 2nd house only a little. Wealth is money held (savings, assets, family wealth): the 2nd and 11th houses and their lords count most, then the 9th, 5th and 10th, and Jupiter, the planet of wealth. Wealth is not a measure of earning: it can be high while someone has no job (for example when Jupiter crosses the 2nd house) and is kept apart for a later family wealth view. Together reads change activity and earned income as four situations: Busy and earning (a change is likely and earned income is 40 or more), Steady earning (earned income 40 or more and nothing changing), Busy, earning weak (a change is likely but earned income is under 40) and Low (neither). None of the charts here records whether anyone had a job; the first strip below does, from the events you recorded. None of it is proved against real income or jobs.

The lines are how strongly the layers support keeping and building money (2nd and 11th houses, with their lords and significators) and earning (6th, 10th and 11th), from 0 to 100, across the period you pick: half from the dasha layers, half from the sky layers. Each point is the average of the days around it (30 days for money held, which does not move day to day, and 14 for money earned); tick the raw box to see the jumpy daily values. It is a relative support, not an amount of money and not a prediction of gains or losses. It cannot see whether there is a job or an income: a stretch with no income at all can show strong support for earning (it then reads as a good time to look for or start earning work, not as proof of earnings), and it was checked this way against a known period of no income and did not follow it (README #528); on the known cases no layer set has yet been shown to pick real events better than chance (README #474). The dashed horizontal lines are this person's own 25th and 75th percentile for money held between ages 18 and 70, so you can see whether a stretch is high or low for this chart.

Four lines for the same period, each on the same 0 to 100 support scale; switch any line off to compare the others. Career is the standing and work side (10th house, with the 6th of service and the 1st of the self). Income is earning from work (6th, 10th and 11th; the line above). Wealth is money kept (2nd and 11th; the line above). Finance is the overall money picture: the average of Income and Wealth. All four are worked out the same way, half from the dasha layers and half from the sky. Move the pointer along the chart (or tap it) to read any date, click to pin one, drag across to zoom, and use the buttons to zoom, pan and switch the marks. Recorded job changes are shown only to compare. Values move in steps because each is a count of how many layers line up.

This is how an astrologer reads earning, and it stands beside the strength strips above, which are unchanged. The strength strips add dasha and sky into one number a month, so they jump with Jupiter's yearly cycle. Earning is a steadier state, so here the dasha sets the phase: each Antardasha is judged by what its lord and the Mahadasha lord are for earning (for earned income the 11th, 10th and 6th houses; for wealth the 2nd and 11th, then the 5th, 9th and 10th), how strong they are, how the Antardasha lord stands from the Mahadasha lord, and whether the lord rules the 8th or 12th (loss and expense) or is a node (unsettling). The phase is strained, steady, good or strong, judged against this chart's own phases between ages 18 and 70 (the lowest quarter of the time is strained, the next 35% steady, the next 25% good, the top 15% strong). Then the Pratyantar moves it one step (up if its lord is a strong earning lord, down if it is a draining one), and the sky moves the month one step (up when Jupiter, with 4 or more of its 8 points where it stands, reaches a house of earning from the lagna or the Moon; down in Sade Sati or when Saturn is 8th from the Moon). The weights were written down before any strip was looked at. It is not proved against real income, and the phase is a level of support, not a record of whether anyone had a job.

Which resolution? The Antardasha is the right unit for a phase: it lasts months to a few years and its dates hold up if the birth time is off by a few minutes (5 minutes moves every dasha date by about one to four weeks). The Pratyantar adds timing inside it, but the short ones (under about two months) are inside that error, so treat them as a hint. The monthly line adds the sky. The more the level changes, the less each change can be trusted.

This applies every principle the engine can compute, at the level of the Pratyantar (the third dasha level, from days to a few months). It stands beside the other sections, which are unchanged. Two things are kept apart. Dasha layers (D1 to D4, up to 4) belong to the whole Pratyantar and do not move inside it. Sky layers (S1 to S9, up to 9) move as Jupiter, Saturn and the others travel, so they are shown on dates (the day-by-day peak and when it falls), never as an average over the period. Each layer is a yes or no question about the chart; the list further down says exactly what each asks. The weights are an astrologer's judgement, not fitted to anyone's life, and nothing recorded was used to set them.

What the layers do not say. They say how well the chart supports earning at that time, not how much money. The amount also depends on experience, the market and the years: the same support at 24 and at 48 will not pay the same, and a chart can look weaker in a later period while the income is higher because the person is worth more. So the layers should be compared within one life, period against period, and read as supported or not supported, never as an amount of money. The table below shows the person's age and the years since the first recorded job for each period, so that stage of life can be read beside the layers. The recorded fact for this person (income higher after every break) can be tested here: the check gives the rank correlation of job order with the layers, which is near +1 if the layers rise with each job and near −1 if they fall.

This only compares. It does not change the reading, and a difference is only worth noticing if it is large and holds when the switches or the ayanamsa change.

A part is the largest of: ruling an earning house, standing in one, half the part of its star lord, and (if on) standing in one by Bhava Chalit; reduced to 85% in planetary war. Green: at or above the level chosen above, so the lord counts in D1 and D2.

What "sky" means. The dasha is fixed by the birth chart: it says which planets' turn it is. The sky is where the planets actually are in the heavens during that stretch (Jupiter, Saturn, Mars, the nodes, the Sun), compared with your birth chart. It changes all the time, so it is read day by day. Each of S1 to S9 is a yes or no question asked of the sky on each day. "S1 100%" means that on every day looked at in this period the answer to S1 was yes; "S7 29%" means yes on 29% of the days. "Most on N of the sky layers counted" is the best single day. The percentages are how often, not how strong, and they are not a probability of anything happening.

Charge reads three things together for each row. Activity: how many of the chosen area's layers (see "Reading of") are on, month by month, scaled 0 to 5, as the mean over the months the period touches (quiet, steady, busy, peak). Support: how well the chart backs earning (dasha layers and sky layers together), rated low, medium or high against this person's own Pratyantars from age 18 to 70 (lowest quarter low, top quarter high). Drain: a running lord ruling the 8th or 12th, or Sade Sati and the like on half the days or more. Charge: stable when activity is quiet or steady (lay low when it is quiet and support is low); when busy, positive if support is medium or high with no drain, negative if support is low with a drain, mixed otherwise. It is a way to read the chart, not a prediction; no layer set has beaten chance on dated events so far. Coarse rows (a Mahadasha) average out, so read charge at the Antardasha and Pratyantar level.

This is the way an astrologer narrows a date, in three steps, and it stands beside the layers and the strength above and below, which are unchanged. 1. Period: the running Mahadasha, Antardasha, Pratyantar and Sukshma lords are each asked whether they signify the houses of the event (the Antardasha must; the finer levels must confirm; a Mahadasha that opposes the event asks for more). 2. Year: the slow planets. For starting work, Jupiter and Saturn both on the 6th, 10th or 11th house (from the lagna or the Moon), or Jupiter there with 4 or more points. For leaving work, Saturn on the 8th, 12th or 10th with a node on the 6th, 12th, 10th or 4th, and Jupiter not protecting the 10th. 3. Month: the Sun or Mars passing a house of the event (6th, 10th, 11th to start; 8th, 12th to leave). A window is the stretch of days in which all three hold together, so it is dated to the day. Different houses are read for starting and for leaving. The houses and rules are an astrologer's judgement written before the code; nothing recorded was used to choose them. A hypothesis, not yet proved.

Four ways of naming career windows are scored the same way against the events you recorded: the layers, the strength, the three steps, and an AI reading of the chart. For the AI reading the model is given only the raw chart: the planets and houses, the Vimshottari dates and the sky (when Jupiter, Saturn and the nodes change sign, and where Mars and the Sun are each month). It is not given a name, a birth place, any recorded event, or any layer, strength or window from this page, and it works out the periods itself. A way that names a lot of the calendar catches a lot of events by luck, so each is judged by its lift: the share of events it caught divided by the share of the calendar it covers. 1 is chance; a way is only worth trusting if it is well above 1 and keeps doing so on events nobody has seen. The recorded events never change a window here.

Covers is the share of working-age time within 30 days of a window. Lift is events caught as a share of events, divided by that cover. By luck is the chance of catching at least this many with that cover by luck alone. With under about 20 events of a kind none of this can settle anything.

The AI reading of the past: the model reads the chart blind, over the last 15 years of working age, and the table scores it against your recorded events beside the formulas.

If the recorded time is only good to the nearest quarter hour, anything built on the divisional lagnas (the career chart D-10 especially) can be a different sign. The Moon moves slowly, so the dasha sequence is steady, but its dates shift by days.

For each shifted time the whole chart and the career layers are recomputed and compared month by month. Dasha boundaries move by days when the Moon's position moves, and a month whose state flips is counted, so even a few minutes of doubt blurs month-level timing. A window should be read as a stretch of months, not a month.

These are rule results, not predictions: each line says which classical career indicators the chart satisfies. The rules are being checked against known life events, so treat them as a work in progress. Houses are counted from the lagna.

The question is read by simple pattern matching, with no AI. It is never answered with yes or no: you get what the evidence looks like for that stage and period.

Primary: lord of the 10th or a planet in it. Supporting: lord of the 2nd, 6th or 11th, a planet aspecting the 10th, or the Amatyakaraka. Karaka: only a natural career karaka (Sun, Mercury, Jupiter, Saturn). Click a lord to see its sub-periods, and a name in the line above to go back up. A green row has both its own lord and the lord one level up primary. Compare the rows with the years of real career events.

Months from age 18 to 70 only. A window is a run of months with enough layers on; it says the evidence lines up, not that anything will happen.

Five kinds of evidence are checked for every month of the life. A cell's colour is how many are on that month. This is a count of facts, not a score or a probability; whether such months have really coincided with events is tested against the events you record.

Record job starts, exits, promotions and other career events that have happened. They appear as marks on the strip above, and the rules are tested against them: do the layers line up more often in the months of real events than in ordinary months? The events belong to this profile and are removed with it.

Optional but important: a month in which someone was settled in a job is not a month in which a new job could have been expected, so it is left out of the "ordinary month" rate for job-getting stages and a window then is not counted as a miss. Months with no situation recorded are treated as open to anything.

A month either side of the event counts as a hit. "Ordinary months" is how often the same rule is true for a month picked at random in the working years; lift is the first figure divided by the second. The verdict corrects for the number of rules tried (the best of many always looks good by chance).

A window you log is saved with the rule version and settings of the day and can never be edited or moved. Once it is over it is judged against the events you recorded: did one fall inside it (a month either side counts)? That keeps the rules honest: a miss stays a miss and is not quietly moved to the next favourable-looking period. Only windows that are current or ahead can be logged, and only while viewing with the profile's saved settings.

Every planet goes round the sky once a day: it rises, climbs to the top of the sky, sets, and passes below you. Michel Gauquelin divided that daily circle into 36 sectors and counted, for thousands of people of known profession, which sector each planet was in at birth. He found that some planets stood a little more often in the key sectors (just after rising and just after crossing the top of the sky, the shaded parts below) for people in some professions. This is a different thing from the signs and houses used elsewhere on this page: it depends only on the daily motion, not on the zodiac.

How to read this: the differences found are a few percentage points across thousands of people (for example 25% of physicians against 21.5% of others have Saturn in a key sector). They show a small statistical pattern in the group. They cannot tell anyone's profession, and they say nothing about dates or events. It is the only chart feature tested on this page's evidence section that repeated in independent data.

An astrologer reads a period by asking who the lord is, how strong it is, what it rules and where it stands, and how it gets on with the lord above it. Those answers change from one period to the next, so each row below carries them. Strength is the planet's Shadbala against its classical minimum (a node borrows the strength of the planet ruling its sign). With the period above is natural friendship plus the position from that lord (6th/8th is strained, a trine is easy, an angle is active). Houses are the houses the lord rules and stands in.

This is the chart read the way a dasha is read: what each lord is, how strong, where it works, how it stands to the one above. It describes a period's character; on 3,570 recorded marriages these ingredients did not pick the date (README #558, #560), so use it to understand a period, not to time an event.

How far to trust it: the cusps and sub lords are calculated exactly as KP defines them. KP's rule that the dasha, bhukti and antara lords must signify the matter's houses on the day was tried on 3,570 recorded marriages and was no better than chance (README #559), so read this as a description of the chart in KP's language.

KP divides each nakshatra into nine unequal parts, one for each lord in the order and proportion of the Vimshottari years. The lord of the part a point falls in is its sub lord, which KP treats as the deciding one. The houses are the Placidus cusps, not whole signs, so a planet can fall in a different house in this view than in the other sections. It uses the Krishnamurti ayanamsa, so degrees differ slightly from the Lahiri chart.

What the birth chart suggests about how the person tends to get on with each part of the family: how close and supportive, or how strained and distant, each bond tends to be. The wording of each is a rank among charts (the weakest 15% read strained or distant, the next 25% mixed, the next 35% generally good, the top 25% warm and supportive).

Support is the combined dasha and sky score of the Pratyantar table (0 to 100); it says how strongly the layers line up for the area, not that anything will happen. The usual range is this person's own 25th to 75th percentile between ages 18 and 70.

A reading of what the birth chart suggests about education: how well learning tends to go, how the mind learns best, the kinds of subjects the chart leans towards, whether study may be interrupted or may take place away from home, and the phases of life that favour study.

A favourable house gives its result only if no planet stands in its obstructing house (Vedha) and the planet has 4 or more points in its own Ashtakavarga for that sign. Vedha is judged on the middle day of each stretch.

The slow planets (Jupiter, Saturn) count most, the Sun, Mars, Mercury and Venus for the month, the Moon for a few days. Vedha is judged on the middle day of each stretch.

Traditional remedies from the texts: prayer, charity and conduct only. There is no evidence that they change what happens; they are given because the texts give them. No gemstone is suggested (that is a costly choice to make with an astrologer in person). They do not replace counselling, medical care or an honest talk between the two people.

The sign-based dasha of Jaimini as K.N. Rao teaches it. It starts at the lagna, so it does not depend on the Moon. Rao says it gives a hint of an event and that the Vimshottari dasha, worked to the sub-sub-period, gives the timing. Checked against the known marriages the 7th-from-lagna tier held 3 of 9 at 16 percent of life (chance 1.5), and Rao's exact pattern (major 7th from the lagna, sub 7th from the Upapada, or the reverse) held one at 2 percent: a small lean, not proof.

The traditional Ashtakoota (Guna Milan) from the two Moons, the Mangal balance and where the two Mahadasha changes fall together. One chart shows promise and strain; astrologers judge how well a couple suits by comparing both. All eight kootas (36 points) are computed. Each koota shows its standard score and, where a classical cancellation (Dosha Bhanga) applies, the score with it, as some sites (OnlineJyotish) award the restored points. The verdict band comes from the Guna score alone, as in the published reports; beside it the "Why" fold lists each chart's own checks (Navamsa, Venus, Jupiter, Mars, the 2nd, 5th, 7th and 8th houses), and a weakness in one chart that the other chart makes up for. It describes two charts together and does not predict the marriage.

The traditional minimum is 18 of 36. Bands on the score with cancellations: under 18 below the minimum, 18 to 24 average, 24 to 32 good, 32 and above excellent. The Vashya and Yoni tables have been compared with one published report only.

The periods and event windows use the same layers as the earning reading, on the houses of marriage: the 7th house, with the 2nd and 11th; the significator is Venus, with Jupiter as well for a woman. The dasha layers (D1 to D4) are fixed for each period and the sky layers (S1 to S9) are asked afresh every few days. Marriage timing is shown as a graded strip (how each month ranks among this person's own months) and the top-third stretches, with the strict windows folded away beneath. Nothing certain follows from any of it, and no recorded date was used to set it. If the time of birth is not known, the houses (counted from the lagna) are unreliable. If gender is not set, both Venus and Jupiter are used.

Ripe period. A planet scores 2 for the 7th house if it rules it, stands in it or is the significator (Venus, and Jupiter too for a woman); 1 if it looks at the house, rules a supporting house (2nd or 11th), shares a sign with the house lord, or is a node acting for such a planet (a node gives the results of the planet it stands with, the lord of its sign, or, less strongly, a planet looking at it: the best of these, one less for the last). It gains 1 more if it ties to the same house in the Navamsa (rules, stands in or looks at it). The Antardasha lord must reach 2 and the Mahadasha lord 1.

Agreement score. Antardasha score + Mahadasha score + targets lit. It shows how many conditions agree; it has not been shown to tell the real window from the others, so no window is marked as the best.

Checked against known dates, honestly: with the Navamsa, the Moon reference and the nodes acting as agents, the windows cover about 36 percent of ages 18 to 45 on average and held 4 of 8 known dates (4 marriages, 4 conceptions). Chance would give about 3 of 8, so this is not yet evidence of skill with so few cases. Ranking the windows by agreement did not help (the three highest held 0 of 8), which is why none is marked as the best. The logic is shown in full, but this is not yet a proven way of finding the date.

This does not predict a marriage date. The shading is only a relative rank of each month among this person's own months. About a third of all days are in the top third, so a date falling inside a stretch proves nothing: nearly any date would. On the four known marriages the date ranked in the top third every time, but their years ranked 19th, 22nd, 20th and 24th of 27 by how much of the year is top-third, which is no better than chance. The honest reading is that the engine cannot yet name the months or years of a marriage. Use the strip to see the pattern of the periods, not to pick dates.

The classical trigger in its strictest form: the Antardasha lord carries marriage, Jupiter and Saturn both reach a house of marriage, and that sky has ashtakavarga support. On eight known dates (four marriages, four conceptions) these held 2, with about 7 percent of adult days covered. They miss most real dates, because real events usually have two or three of the three links, not all.

The sign-based dasha of Jaimini as K.N. Rao teaches it. It starts at the lagna, so it does not depend on the Moon. Rao says it gives a hint of an event and that the Vimshottari dasha, worked to the sub-sub-period, gives the timing. Checked against the known conceptions no tier did better than chance (the best held 2 of 8 at 25 percent of life, chance 2.0).

The periods and event windows use the same layers as the earning reading, on the houses of children: the 5th house, with the 9th, 2nd and 11th; the significator is Jupiter. The dasha layers (D1 to D4) are fixed for each period and the sky layers (S1 to S9) are asked afresh every few days. Children timing is not claimed; the periods table is the answer, with the strict conception windows folded away beneath. Nothing certain follows from any of it, and no recorded date was used to set it.

Ripe period. Children rule set C1.0, from the astrologer's outline: the 5th house, with the 2nd and 9th; Jupiter as the Putrakaraka; the tie is made in the Saptamsa (D-7); natal Jupiter's sign is also a target, and Rahu or Ketu on a target adds to the agreement. These are windows for CONCEPTION, not birth: add about nine months for the birth. A planet scores 2 for the 5th house if it rules it, stands in it or is the significator (Jupiter); 1 if it looks at the house, rules a supporting house (2nd, 9th or 11th), shares a sign with the house lord, or is a node acting for such a planet. It gains 1 more if it ties to the same house in the Navamsa. The Antardasha lord must reach 2 and the Mahadasha lord 1.

Checked against known dates, honestly: with the children rule set the windows cover about 34 percent of ages 18 to 45 on average and held 1 of 4 known conceptions (the earlier common set held 2 of 4); chance would give about 1.4. For Chakri and Phani, whose child is the same event, neither chart has the conception in its windows and the two charts overlap in no window containing it. Four conceptions are three independent events, so nothing can be concluded.

Timing for children is not claimed. On four known conceptions the combined score ranked at the 33rd, 53rd, 56th and 92nd percentile of the person's own days (the middle is 55), so it does not tell a conception day from an ordinary one. The periods table (which Antardashas and Pratyantars carry children) is the answer these layers can bear.

About 9,000 first marriages of notable men were checked against every dasha pair, the double transit on the 7th house, the Venus periods, the Jupiter and Saturn transits and the links of the dasha lords to the 7th house. Nothing held up for men: in every dasha window tried, marriages were no more common than chance, so the usual years above are the whole of what the data can say.

About 2,700 first marriages of notable women were checked the same way. Two windows held up, and for men nothing did. Both are small: most marriages still happen outside them, and they cannot date any one marriage.

About 15% of a life; it held 16.8% of marriages against 15.0% by chance (about an eighth more). Where it overlaps the Jupiter / Saturn pair, 0.9% of marriages fell in 0.4% of life.

What it means: where a window falls in the years when marriage is likely for you, marriage is a little more common in it than in other periods of those years. It is not a prediction for you, and the other dasha pairs and transits tested showed nothing.

For each career event recorded for this person, this places the date on the Income and Career lines of the graph, as a percentile of the person's own range: 50 is what a random date gives, 75 or more means the lines were high on that date, 25 or less means low. It is the same measure used in the large tests in the evidence section.

Each period is read the way an astrologer reads it: which lords are running down to the period's own level, whether they rule, stand in or look at the houses of the matter and are strong, then where Jupiter and Saturn are in the middle of it. Strong, Medium, Low or Weak is the plain sum. The period you choose in the line above the table also decides the dasha blocks under it: they are that period's sub-periods, covering the years it covers. Compare it with sections 18 and 22 above.

The Arudha of a house is how that matter appears to others (the image), as against what it really is. A1 is the image of the person; A7 of partnerships; A10 of work and standing; A12, the Upapada, is read for the marriage partner.

Planets in the 2nd, 4th and 11th from a house help it (the 5th as well when the 2nd is empty); planets in the 12th, 10th and 3rd obstruct that help (the 9th the 5th). The help stands when the obstructing planets are fewer than the helping ones.

How far to trust it: these are calculations from the classical rules and agree with an independent program where the rules are fixed; none of them has been tested on real events, so read them as the chart described in Jaimini's and Parashara's terms.

The Atmakaraka (the planet with the most degrees in its sign) gives the Karakamsa, its navamsa sign. Jaimini reads the life's direction from the planets in and aspecting that sign and from the signs counted from it: 2nd, 5th, 7th, 10th and 12th.

Shadbala is the old way of asking how much a planet can deliver. It adds six sources of strength: position (sign, divisional charts, house), direction (the angle it stands at), time (day or night, the Moon's phase, the lords of the year, month, day and hour, the Sun's declination), motion (how it moves against the Sun), nature (fixed by the planet) and aspects (helped or hurt by others). The total is in rupas (60 points each) and is compared with the classical minimum for that planet.

Points are shashtiamsas (virupas). Rahu and Ketu are not given a Shadbala in the texts. Conventions follow the AstroSage printout: the lords of the year and month are counted from B.V. Raman's base year, the Moon's phase is not doubled, and the Sun's declination for the time strength comes from its longitude alone. The motion part uses the Surya Siddhanta mean positions, so Mercury's and Venus's motion points can differ from a printout by a few points.

How far to trust it: the calculation was checked against an AstroSage printout (the planets rank in the same order and the totals agree within about 0.5% for six of the seven planets; Mercury differs by one position convention). Whether a stronger dasha lord gives better results has not been shown on real events (README #560).

The points each planet gets in each sign (its own Ashtakavarga) are reduced in two steps. Trikona Shodhana takes the smallest of the three signs of a trine from all three (nothing is taken if one of them is empty). Ekadhipatya Shodhana deals with the two signs a planet rules (for Mars, Mercury, Jupiter, Venus and Saturn) by whether they hold a planet. What is left is the planet's reduced points; the Rasi pinda weights them by sign, the Graha pinda by the planets standing in the signs, and the Sodhya pinda is the two together, a classical measure of how much a planet can give over a life.

How far to trust it: the points and the reductions follow the classical rules and agree with an independent program; whether the pindas say anything about a life has not been tested on real events.

This follows chapters 43 and 44 of Brihat Parashara Hora Shastra and shows every step, so you can check it against your own working. It gives three lifespans (Pindayu, Amsayu, Naisargayu) with the four reductions, the years of the Lagna, the pair-of-signs method with its class (long, medium, short), the yogas the book names, and the Marakas (lords of the 2nd and 7th and the others the book lists). Where the book is open to more than one reading, the choice made is written in the section. It checks against the book's own worked example to a few hundredths of a year, but it is reference only: it feeds no reading, and it has not been tested against real lives.

At the top is an astrologer's verdict: one range of years. It is a summary made for this page and is not a rule of the book: the four figures (the three lifespans and the pair-of-signs method) are sorted into the bands of chapter 44 (short to 32, medium to 64, long beyond), the band holding most of them is taken, and the range runs from the lowest to the highest figure in it. Its cautions are printed with it. The section also checks the early-life evils of chapter 9 (Balarishta) and their antidotes in chapter 10, rule by rule; the rules about the mother, father and family are not included.

The dashas are now one section with tabs: Vimshottari, the dashas that run by the Moon's nakshatra, the sign dashas, the dashas from birth, the year dashas and the periods beside your recorded events. Each tab opens from the left menu as a sub-section. The Special points section is split into tabs in the same way.

This puts the same birth through up to four sets of choices side by side: ayanamsa, calculation system (modern or the Surya Siddhanta), house system and nodes. Each column is worked out in full, and what differs from the first column is marked. The calculation system moves the planets, so signs, nakshatras, dashas and every reading can change. The house system changes only the house a planet is counted in, which matters to the readings that count by house (marriage, children, career and the yogas that name a house). If a reading changes with a choice, the matter rests on that choice. Nothing here is stored.

Chapter 35 of Brihat Parashara Hora Shastra names 32 patterns that depend only on where the seven planets (Sun to Saturn) stand: all in one kind of sign (Rajju, Musala, Nala), benefics or malefics in three angles (Maala, Sarpa), the twenty shapes of the Akriti group (Gada, Sakata, Kamala and the rest), and the seven that count the signs occupied (Gola to Veena, shown only when no other pattern is formed). The section also shows the Vesi, Vosi and Ubhayachari yogas of chapter 38. It is reference only: it feeds no reading, and the effects are the book's in short words, not tested against real lives.

For the 150 Nadi amsas (D150) the section gives the number, the sign and the name of the part in both of the two traditional name lists, in the equal and in the unequal scheme (A. V. Raveendran, 2025). For the other divisions: each part of a sign has a deity, named in chapter 6 of Brihat Parashara Hora Shastra. The section lists the deity of the part each planet stands in, for the fourteen divisions to which the book gives deities. In the Shashtiamsa (D60) the book also marks each part benefic or malefic. This is reference only: it feeds no reading, and it has not been tested against real events.

The Sarvatobhadra chakra is a square of 9 by 9 cells. Round the edge stand the 28 nakshatras (Abhijit counted); inside are the vowels, the letters, the twelve signs and, in the middle, the five groups of tithis with the weekdays. A planet in a nakshatra obstructs (the old word is vedha) the cells in three lines from it: straight across the square and along the two diagonals. The section shows where the planets of the chosen date, or of the birth chart, stand, which birth nakshatra, sign, tithi group and weekday their active line reaches, and how strong the planet is (three times when exalted, twice when retrograde, a half when debilitated). It is read from a printed form and two papers, and the lines agree with every example in them; it has not been tested against events, and nothing in the readings uses it.

Three colours. Green: the rule was checked against the book itself. Amber: the book describes it but we have not checked it line by line. Red: none of the books we hold describes it, so it rests on modern practice and on agreement with an independent program (which shows the arithmetic is the same, not that the rule is classical). We could search the text of the Parashara Hora, the Brihat Jataka and the Jaimini book; the text of Raman, Saravali and Sarvartha Chintamani could not be searched reliably, so a few red items may be in those.
