Darakaraka: The Planet That Describes My Partner

Take the seven planets from the Sun to Saturn, look at how far each one has travelled into the sign it occupies, and rank them from the highest degree to the lowest. The planet at the highest degree is your Atmakaraka, the significator of the self. The planet at the lowest degree is your Darakaraka, the significator of the spouse and of the partnership. Seven planets, seven places in the ranking, and the ranking comes out different in almost every chart.

That is why no general answer can tell you which planet yours is. Your rising sign does not decide it, your Moon does not decide it, and two people born in the same city on the same day can end up with different Darakarakas if they were born a few hours apart. The only thing that decides it is where your seven planets happened to sit inside their signs at the minute you were born.

The rule, stated completely

Every planet has a sidereal longitude, which is its position measured around the whole 360-degree circle of the zodiac against the fixed stars. Strip out the whole signs and you are left with the degree inside the sign, a number between 0 and 30. That single number is what the ranking uses. Nothing else about the planet enters the calculation.

Here is a real chart, born on 14 June 1988 at 07:40 in Mumbai, with its seven planets already sorted.

The Sun is at 29 degrees of Taurus and Saturn is at 6 degrees of Sagittarius, so the Sun takes the first rung and Saturn takes the last one. The signs themselves play no part in the sorting: Saturn would still be last if it were at 6 degrees of Aries or 6 degrees of Cancer.

Two exclusions are worth knowing before you try this on your own chart. Ketu, the descending lunar node, is never eligible, and that is arithmetic rather than an opinion. Ketu is defined as Rahu plus 180 degrees, and 180 degrees is exactly six signs, so Ketu's degree inside its sign is identical to Rahu's in every chart that has ever been cast. Ranking both would be ranking the same number twice. Rahu itself is a real question with a definite answer, and it has its own section below.

The seven portfolios

The ranking is more than a sorted list of planets. Each place in it carries a portfolio, and the planet that lands there becomes the significator of that part of life for the whole chart. This is the layer the two worked charts on this page are read through, so it is worth having in front of you.

Chart B is the second worked example on this page, born 9 March 1995 at 22:25 in Bengaluru. Both charts are computed in full further down.

There is one labelling fork inside the seven-karaka scheme, and it is easier to settle now than to discover halfway through a reading. The labels above are the K. N. Rao and Iranganti Rangacharya set, which is what the Indian consumer web shows. Read literally, BPHS 32.16 merges the child significator into the mother significator and keeps a separate father significator, which puts Pitrikaraka at rank 5 instead of Putrakaraka. Both lists are called the seven-karaka scheme and they are not the same list. The part that matters here is that rank 7 is the Darakaraka under both of them, so nothing about your spouse significator depends on which labelling your astrologer uses. The fork bites at rank 5 and nowhere else.

The second rung, the Amatyakaraka, is the one most often read alongside the Atmakaraka, because a career reading needs both: the first names what the life is about and the second names the vehicle it travels in. That pairing used to live on its own page at Amatyakaraka and Atmakaraka and is covered here, in the table above and in the two charts below.

Your Darakaraka is probably not your 7th lord

The next question, once you have the planet, is how it relates to the part of the chart you may already have been told describes marriage: the 7th house and the planet that rules it. The answer is that the two are independent, and the independence is measurable.

We computed 100,000 charts on our own engine, with birth dates spread evenly across 1975 to 2005, clock times spread evenly across the day, and birthplaces drawn evenly from ten Indian cities. In that sample the Darakaraka and the 7th lord were the same planet in 14.05% of charts. One in seven is exactly what you get by drawing a planet at random out of seven, which is another way of saying the ranking knows nothing about your rising sign.

The house the Darakaraka occupies tells the same story. Houses here are counted whole sign from the lagna, meaning the sign that was rising on the eastern horizon at your birth: that whole sign is the 1st house, the next whole sign is the 2nd, and so on around the circle.

Every house gets its 1-in-12 share and the 7th gets no more than any other. So a Darakaraka sitting in the 7th house is not the norm, and its absence from the 7th is not a warning sign. Counting all three ways the two can connect, the Darakaraka rules the 7th, or sits in it, or casts an aspect onto it in 33.76% of charts, which leaves two charts in three where the two descriptions are built from entirely separate material.

That is the useful finding, and it is the reason this page exists separately from the 7th-house reading. You have two independent descriptions of the same person. Where they name the same planet, which happens in about one chart in seven, the description is unusually specific and you can lean on it. Where they differ, you have two true things about one relationship rather than a contradiction, and the honest reading names both. The house-based half of that reading is set out in full in What Will My Spouse Be Like.

Venus belongs to everyone. The Darakaraka is only yours.

Vedic astrology carries two kinds of significator, and mixing them up is the most common way this topic goes wrong. Venus is the fixed significator of marriage and of the wife, and it holds that job in every chart ever cast, including yours, including charts where Venus sits nowhere near the 7th house. Our marriage engine treats it exactly that way: Venus is the primary significator in every chart, Jupiter carries the additional role of significator of the husband in a woman's chart, and when that second layer is not applied the reading says so in plain words instead of dropping it silently.

The Darakaraka is the movable significator. Chara means movable, and what moves is which planet holds the job, decided fresh for every chart by the ranking above. So the fixed answer and the movable answer are both live at once, and they coincide only sometimes. Venus came out as the Darakaraka in 14.49% of our 100,000 charts. In those charts the two significators are the same planet and everything Venus does in the chart is doing double duty. In the other 85.51%, Venus still describes marriage in general while the Darakaraka describes this partnership in particular.

Chart B is one of the 14.49%: its Darakaraka is Venus. Chart A is not. Its Darakaraka is Saturn, while Venus sits at 27°49' of Taurus in the 12th house doing its ordinary fixed-significator work.

Why your Darakaraka sits at such a low degree

Anyone computing this for the first time notices that the Darakaraka is usually at some small number of degrees, often under 5 and sometimes under 1. That is not a coincidence and it is not a sign of weakness. It is what taking the minimum of seven numbers does.

Across the same 100,000 charts, the Darakaraka's degree inside its sign had a mean of 3°41'42" and a median of 2°51'40". It was under 1 degree in 21.06% of charts and under 5 degrees in 72.54%. For contrast the Atmakaraka, which is the maximum of the same seven numbers, had a mean of 26.12 degrees and a median of 27.02.

The consequence matters more than the number, because it constrains which nakshatra your Darakaraka can be in. A nakshatra is one of 27 equal segments of 13°20' that the same zodiac is also divided into, and each one carries its own ruling planet, deity and character. Since those segments are 13°20' wide and the signs are 30 degrees wide, the two grids do not line up, and each sign begins part-way inside a nakshatra.

A planet that is nearly always in the first few degrees of its sign is therefore nearly always in one of those twelve nakshatras, and the observed distribution follows exactly.

All 27 do occur, so nothing here is impossible, but the bottom six are rare enough to be worth naming. Every Venus-ruled nakshatra begins at 13°20' of its sign and every Mercury-ruled one begins at 16°40', and a planet sitting at a median 2°51' almost never reaches that far. A Darakaraka in Revati turned up once in roughly ten thousand charts. If yours is one of those six, it is a genuinely uncommon placement rather than a rounding artefact.

One thing the low degree does not constrain is the pada, the quarter of a nakshatra a planet falls in. The four padas came out at 24.69%, 25.43%, 24.17% and 25.71%, which is even, because the nakshatras covering the opening arcs of signs are wide enough to hold all four quarters.

How close was the call in your chart

The ranking gives you a single answer, but it does not tell you by itself whether that answer was decided by a wide margin or by an arcsecond. It should, so we compute it.

In the 100,000-chart sample the gap between the sixth rung and the seventh, the gap that decides your Darakaraka, had a median of 2°57'. It was under 1 degree in 20.21% of charts and under 0.1 degrees in 2.15%. It fell inside one arcsecond in 7 charts out of 100,000.

Chart A settles it at 14°21'33", which is not a close call by any standard: Mars at 20°22'55" and Saturn at 6°01'21" are not going to swap places. Chart B settles it at 6°35'54", also comfortable. But chart B does contain a near tie higher up the ranking, between Mars at 20°48'17" and Jupiter at 20°47'19", which is 58 arcseconds apart. That pair decides which planet is the child significator and which is the rival significator, and it leaves the Darakaraka untouched.

When two planets do land inside one arcsecond of each other, we flag the pair and return the higher value rather than resolving it silently, because the classical sources conflict on what should happen and choosing one of them quietly would hide the choice from you. The tie-break we do apply, so the answer can never depend on the order the planets happen to be listed in, is Rangacharya's natural strength order: Sun, Moon, Venus, Jupiter, Mercury, Mars, Saturn, Rahu.

What a wrong birth time does to it

The ranking uses degrees rather than the rising sign, so it survives an imperfect birth time far better than the houses do. We measured how much better by recomputing each chart's whole ranking at fixed offsets either side of the recorded time and checking whether the Darakaraka moved.

The first three rows come from the 100,000-chart sample and the last three from a 20,000-chart extension of it. Read them as a decision rule. A birth time recorded to the minute or the quarter hour gives you a Darakaraka you can rely on. A birth time you are guessing at within an hour still leaves better than a nine-in-ten chance of the same answer. A chart with no birth time at all is normally computed at noon, and noon can be up to twelve hours wrong, at which point the answer is close to a coin toss and should be treated as one.

That is the significator itself. The house it sits in is a separate question with a stricter answer: houses are counted from the rising sign, the rising sign changes roughly every two hours, so without a real birth time there are no houses at all. The usual fallback is to count the same houses from the Moon's sign instead, which the Moon holds for about two and a half days and which a missing clock time therefore rarely disturbs. In chart A the Darakaraka is in the 7th house from the lagna and the 8th from the Moon. In chart B it is in the 4th from the lagna and the 9th from the Moon. Everything else on this page, the sign, the nakshatra, the dignity, the Navamsa position, the dispositor chain and the dasha windows, is available with or without a birth time.

Seven karakas or eight

If a second calculator has handed you a different Darakaraka, this is the most likely reason, and it has a definite answer rather than a shrug.

The dispute is textual and it is old. Jaimini's Upadesa Sutra 1.1.10 reads saptanam astanam va, "of seven or of eight", with the word "or" sitting inside the sutra itself. BPHS 32.1-2 recites three positions and settles none of them. K. N. Rao and Rangacharya teach seven. P. V. R. Narasimha Rao, who wrote the Jagannatha Hora software, teaches a conditional eight that switches on only when two of the seven share the same whole degree.

We use seven, and here is why. It is what our marriage reading has always used, so any other default would silently change a reading somebody has already paid for. It sidesteps the mean-versus-true-node question entirely, since Rahu's position is the only place the choice of node would move a rank. It is the modal teaching position in India. And the conditional rule is unstable in a way that disqualifies it as an interface even where it is defensible as a reading: it fires on 52.54% of charts if "the same degree" means the same whole degree, on 1.14% at the arcminute, and on 0.011% at the arcsecond. A rule whose trigger rate moves by a factor of nearly five thousand depending on how precisely you compare is not a rule you can put in front of a reader. We rank at full floating-point precision, where it never honestly fires.

Under the eight-planet scheme Rahu joins the pool, and its degree is reversed before ranking: its key becomes 30 minus its degree in the sign, following BPHS 32.5 and its stated reason vilomagamanat, backward motion. The arithmetic behind that is that Rahu enters every sign at 30 degrees and leaves it at 0, so 30 minus its degree is the arc it has actually travelled.

Measured across the 100,000 charts, adding Rahu moves the Darakaraka in 12.78% of charts, the Atmakaraka in 12.40%, and the Amatyakaraka in 25.23%. The career significator is the rung most exposed to this question, which is why a calculator that hides its scheme is hiding the one setting that decides your career karaka. That was the subject of Seven Karakas or Eight, and it is settled here.

Chart A is one of the 12.78%. Rahu sits at 24°43'46" of Aquarius, so its reversed key is 5°16'14", which is lower than Saturn's 6°01'21". Under the eight-planet scheme Rahu takes the last rung and becomes the Darakaraka, Saturn moves up to the rival significator, and two other rungs shift with them. Chart B is not one of them: its Rahu is at 14°23'22" of Libra for a reversed key of 15°36'38", comfortably above Venus at 14°11'25", so Venus keeps the last rung either way. If you want the alternative answer for your own chart, we compute it and show it next to ours rather than choosing for you in silence.

Retrograde planets are not reversed

There is a second place two calculators can legitimately disagree, and chart A happens to show it clearly.

The 30-minus reversal applies to Rahu alone. We do not extend it to ordinary planets that are in retrograde motion, meaning temporarily appearing to travel backwards against the stars as seen from Earth. No classical text extends it, and BPHS 32.5 gives the rule for Rahu with a reason specific to Rahu.

The counter-argument is worth stating because it is the strongest one against the choice we made. Rahu's reversal is about how it enters a sign rather than which way it happens to be moving at any instant: Rahu always enters at 30 degrees and always leaves at 0. A planet like Mars that is temporarily retrograde still entered its sign at 0 degrees and will still leave it at 30. On that reading the reversal was never a rule about retrograde motion at all, so extending it would apply it to cases it was never about. That is the reasoning we follow.

Chart A makes the stakes concrete. Its Saturn is retrograde and it is the Darakaraka at 6°01'21". Extend the reversal and Saturn's key becomes 23°58'39", which lands between the Moon at 26°00'57" and Mars at 20°22'55". Saturn would move to the sixth rung and Mars would become the Darakaraka instead. So this is not a technicality that lives in a footnote. In this chart it changes the answer outright, and any calculator applying the extension will hand you a different planet.

Reading the Darakaraka once you have it

The planet's name is the beginning of the reading rather than the whole of it. Six things are read from it, and each answers a different question.

Its sign says what material the partnership is made of. Its house says which area of life the partner shows up through, and needs your birth time. Its nakshatra and pada are the finer grid, and they hand the planet to a second ruler: a Darakaraka in Moola answers to Ketu at that level whatever else Saturn is doing. Its dignity says how well the planet can act from where it sits: exalted means placed in the sign where it is strongest, debilitated means the sign opposite that one, own sign means it is at home. Its dispositor, the ruler of the sign it occupies, is the planet the Darakaraka has to work through, and following that from planet to planet gives you a chain. Its dasha periods say when its part of the story is scheduled.

The Navamsa is the ninth divisional chart, which is a second chart derived by cutting every sign into nine equal parts of 3°20' and reading which sign each part maps to. It is the chart marriage is traditionally judged in, so a planet's position there is read alongside its birth-chart position rather than instead of it. A planet landing in the same sign in both charts is called vargottama, meaning "best in the divisions", and neither Darakaraka here is.

The same divisional chart gives the first rung a term of its own that often turns up beside this one. The Karakamsa, which is the Navamsa sign your Atmakaraka occupies, is where a Jaimini reading of life purpose is taken from. It comes out as Virgo in both charts here, holding Mercury and Venus in chart A and the Moon in chart B. It belongs to the significator of the self rather than the significator of the spouse, so it plays no part in the reading below, and it is set out in full at Atmakaraka and Karakamsa in the Navamsa.

Chart A, read end to end

Born 14 June 1988, 07:40, Mumbai. Gemini rises at 21°17', in Punarvasu pada 1.

The Darakaraka is Saturn at 6°01'21" of Sagittarius, in the 7th house. That is the 8.15% case: the movable significator of the spouse has landed in the house of the spouse. Saturn is also the only planet in that house, so nothing else is describing the 7th. When the two independent descriptions point at the same place like this, the reading gets simpler rather than louder, because there is nothing to reconcile.

The 7th lord here is Jupiter, since Gemini rising puts Sagittarius on the 7th and Jupiter rules Sagittarius. Jupiter sits at 28°46'18" of Aries in the 11th house, the house of the wide circle and of gain. So the arrival of the partnership is described by Jupiter from the 11th, and the standing character of it is described by Saturn from inside the 7th. Those are different statements about the same relationship and both are on the chart.

Saturn is in Moola pada 2. Moola is ruled by Ketu, presided over by Nirriti, symbolised by a bunch of roots, sorted under Kama among the four aims of life, and recorded with the quality "foundation, investigation, uprooting". So the significator of the spouse in this chart answers to Ketu at the nakshatra level, which is a second ruler layered on top of Saturn's own nature, and the significator's character is about what lies underneath something rather than what is on the surface of it.

Saturn's dispositor is Jupiter, because Jupiter rules Sagittarius. Jupiter sits in Aries, whose ruler is Mars. Mars sits in Aquarius, whose ruler is Saturn. The chain closes on itself: Saturn to Jupiter to Mars and back to Saturn. A closed chain of that kind means no planet in it can be resolved without the others, so the partnership significator, the 7th lord and the rival significator in this chart are structurally tied together and get read as one group.

In the Navamsa, Saturn moves to Taurus, a sign ruled by Venus, the fixed significator of marriage. It is in neutral condition there, so the ninth chart neither strengthens nor weakens the significator. What it does is hand it to Venus.

Under the eight-planet scheme this whole reading would be about Rahu instead, which sits at 24°43'46" of Aquarius in the 9th house. We use seven, so it is about Saturn.

Chart B, read end to end

Born 9 March 1995, 22:25, Bengaluru. Libra rises at 22°56', in Vishakha pada 1.

The Darakaraka is Venus at 14°11'25" of Capricorn, in the 4th house. This is the 14.49% overlap: the fixed significator of marriage and the movable significator of the spouse are the same planet. Everything Venus does in this chart is doing both jobs at once, and there is no second planet to weigh it against.

Venus sits in the 4th house, the house of home, mother, land and settledness. The 7th lord is Mars, since Libra rising puts Aries on the 7th, and Mars sits at 20°48'17" of Cancer in the 10th house, where it is debilitated, meaning placed in the sign where it acts with least support. Ketu occupies the 7th house itself. So the arrival is described by a weakened Mars from the house of public work, while the standing description of the partner sits quietly in the house of home. Those two do not agree, and the disagreement is the reading: the same relationship looks difficult from the direction it arrives and settled from the direction it lives.

Venus is in Shravana pada 2. Shravana is ruled by the Moon, presided over by Vishnu, symbolised by an ear and three footprints, sorted under Artha, and recorded with the quality "learning, listening, connection". So the spouse significator here answers to the Moon at the nakshatra level, a different second ruler from Venus's own nature, and one that softens it.

Venus's dispositor is Saturn, because Saturn rules Capricorn, and Saturn sits at 21°39'56" of Aquarius, which is its own sign. The chain is one step long and ends there. That is the cleaner of the two structures: the partnership significator has to work through exactly one planet, and that planet is at home and does not pass the question on.

In the Navamsa, Venus moves to Taurus, its own sign, so the ninth chart returns it to full strength. The birth chart has Venus in neutral condition and the Navamsa has it at home, which is the direction you want that difference to run: the significator of the partnership is stronger in the chart describing what the partnership becomes than in the one describing how it arrives.

The dasha windows your Darakaraka owns

Naming the planet answers "who". The dasha system answers "when", and it is the part most readers actually came for.

Vimshottari is the standard timing system in Indian astrology. It divides a notional 120-year life among nine planetary rulers in a fixed sequence and with fixed shares: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17. Which ruler you start with, and how much of its period is already spent at birth, is read from the nakshatra your Moon occupied when you were born. Each major period, called a mahadasha, is then subdivided into nine antardashas in the same sequence and in the same proportions, and each of those is subdivided again into pratyantar, meaning the third level of the same division.

Because the sequence includes every ruler at every level, your Darakaraka gets one antardasha inside every mahadasha of your life, plus its own mahadasha if you live to reach it. Those are the dated windows in which the significator of the partnership is running the chart.

Chart A's Darakaraka is Saturn, whose mahadasha runs 19 years.

On 26 August 2026 this chart is in its Jupiter mahadasha and its Rahu antardasha, with a Saturn pratyantar running from 28 April 2026 to 14 September 2026. So the spouse significator is active at the third level right now, and it takes over the whole chart in January 2028.

Chart B's Darakaraka is Venus, whose mahadasha runs 20 years.

This chart is inside its Darakaraka antardasha as of 26 August 2026 and stays there until April 2028. That is a two-and-a-half-year window in which the significator of the partnership is the sub-ruler of the chart, and it is exactly the kind of window a marriage-timing reading exists to find. The mahadasha of the same planet does not arrive until 2076, which is worth saying plainly, because a reading that looked only at mahadashas would report nothing here and be wrong about it.

What the population looks like

Two questions come up often enough to deserve real numbers rather than an impression: which planet is most likely to be your Darakaraka, and whether that answer is a fact about the planets or a fact about when you were born. It turns out to be both, and the second half is the more interesting one.

Here is the Darakaraka distribution across the 100,000 charts, with the 7th lord distribution beside it for contrast.

The 7th lord column is steeply uneven, because it is a fixed function of the rising sign and signs do not take equal time to climb the horizon at Indian latitudes. The Darakaraka column is nearly flat, because it depends on nothing but degree. Only Jupiter is far off the 14.29% an even split would give.

Now the honest part. That Jupiter figure is not a permanent property of Jupiter. It is a property of the birth window we measured. Recomputing the same distribution over births spread across 1900 to 2100 gives Jupiter 13.18% and Saturn 13.85%, with the whole column compressed into the range 13.18% to 15.45%. Over the narrower 1960 to 2010 window Jupiter comes out at 12.39%. Sweeping every planet's degree inside its sign day by day tells you why: across 1975 to 2005 Jupiter sat below 5 degrees on only 11.59% of days against roughly 16.6% for the fast planets, and across 1900 to 2100 that same figure is 15.73%, close to even. The same sweep puts Saturn at 19.30% in the short window and 16.62% in the long one. Both slow planets were sitting in unrepresentative parts of their signs during the three decades we sampled.

The reason the effect shows up in Jupiter at all is that Jupiter spends more of its time in the middle of a sign than at either end. Between 5 and 25 degrees it is found 76.97% of the time against about 66.7% for the Sun, Moon, Mars, Mercury and Venus, and it is under-represented at both edges rather than only one, so it reaches the bottom of the ranking less often. It was retrograde in 27.95% of the sample, and its retrograde stretch is more mid-sign still at 83.13%.

So read the first table as a description of people born in India between 1975 and 2005, which is most of the adults asking this question, and not as a law about planets. We are stating it that way because a population figure quoted without its window is the kind of number that gets repeated for years after it stops being true.

The rest of what the Darakaraka looks like across those charts:

One footnote on that table, because the two ways of counting "at home" disagree by more than sampling noise. The dispositor chain has 14.48% of Darakarakas ruling the sign they sit in, while the dignity row has 13.11% in own sign. The gap is Mercury in Virgo, the one sign a planet both rules and is exalted in, and which the dignity table records as exalted.

Getting your own

Your Darakaraka needs your birth date, and it is worth another decimal place if you have your birth time.

Our free chara karaka tool computes the whole ranking from Atmakaraka down to Darakaraka without an account. It returns each rung's planet, its degree to the arcsecond, its sign and house, its Navamsa sign, the margin between the first two rungs, a flag on any pair inside one arcsecond, what the eight-planet scheme would return instead, and the ayanamsa, node type and tie-break we used to get there. That is enough to answer "which planet is my Darakaraka" completely, and to see how close the call was. Our free kundli tool gives you the same chart in full if you want to check the arithmetic yourself against the rule at the head of this page.

What a saved chart adds is the reading rather than the ranking. With your birth details on file, the Darakaraka's nakshatra, pada, nakshatra ruler and deity are resolved for you, its dignity is computed in both the birth chart and the Navamsa, its dispositor chain is followed to its end, and its Vimshottari windows are dated the way the two tables above are dated, including which one is running today. Chart Chat then answers follow-ups against your own numbers instead of a general rule, so "my Darakaraka and my 7th lord disagree, which do I weight" becomes a question with your chart's answer rather than an essay's answer.

If timing is what you want rather than description, our Marriage Timing report reads this same material against your dasha sequence and Jupiter's transits over the marriage axis, and returns dated windows together with the age band your chart favours.

Method note. Every degree, sign, house, nakshatra, pada, dignity, Navamsa position, dispositor chain and dasha date on this page was computed with the AstroMedha Vedic engine using the Lahiri ayanamsa and the Swiss Ephemeris, with mean lunar nodes and whole-sign houses. The chara karaka ranking uses the seven-planet scheme (BPHS 32.1), ranked on unrounded sidereal longitude, with Rangacharya's natural strength order as the tie-break and any pair inside one arcsecond flagged rather than resolved. Degrees are shown to the arcsecond because that is the precision of the computation, not a claim about the exactness of a recorded birth time. Citations for the scheme: BPHS 32.1-5, BPHS 32.13-17, and Jaimini Upadesa Sutra 1.1.10, whose sutra numbering we have not checked against a print edition. Population figures come from 100,000 charts generated on 26 August 2026 with seed 20260826: birth dates uniform over 1975 to 2005, clock times uniform over the day, birthplaces drawn uniformly from Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, Pune, Ahmedabad, Jaipur and Lucknow. The 3-hour, 6-hour and 12-hour birth-time rows come from a 20,000-chart extension with seed 20260827. The 1900-2100 and 1960-2010 comparisons were run the same way over those windows.
