Upapada Lagna Calculator

An arudha is an image. Take a house, find its lord, count the distance from the house to the lord, then count that same distance again from the lord. Where you land is the arudha of that house — what the house looks like from outside rather than what it is. The Upapada Lagna is the arudha of the twelfth house, and the twelfth is the house of loss, expenditure and what is given away.

That the marriage point is derived from the house of giving away is the whole idea, and it is worth stating rather than skipping. In the tradition marriage is read through what a person releases into a partnership rather than through what they acquire from one. Jaimini's system is built on images of this kind, and the Upapada is the clearest of them.

Two exceptions apply and the engine applies both. If the computed arudha falls in the twelfth house from the ascendant it moves to the ninth, and if it falls in the sixth it moves to the third. The rule exists because an arudha landing on its own house or on the seventh from it produces no image at all — the reflection coincides with the object — and the classical correction displaces it by a trine.

The second house from the Upapada

Read in the tradition for the durability of the marriage, with benefics there taken as supportive and malefics as indicating strain. This page reports the UL and its lord and does not issue a verdict from the second house from it, because that reading is prediction dressed as arithmetic.

The Darakaraka

The spouse significator in the chara karaka scheme: the graha with the lowest degree in its sign. It is reported alongside because a Jaimini marriage reading uses both, and the Atmakaraka page explains the seven-karaka scheme this repo follows.

The Arudha Lagna

The arudha of the first house, the public image. It is computed by the same rule with the same exceptions and is reported here for the comparison, because the relationship between AL and UL is one of the readings Jaimini practice actually uses.

The combinations above were tested against a Gemini ascendant, and that single fact decides every one of them. A yoga defined by the second and eleventh lords is a statement about two specific planets, and which two depends entirely on which sign was rising. Change the ascendant and you change the lords, the categories they belong to, and therefore the answer.

The categories are the vocabulary the whole yoga literature is written in. Kendras — the 1st, 4th, 7th and 10th — are the pillars: the houses that hold a chart up. Trikonas — the 1st, 5th and 9th — are the sources of fortune and merit. A Raja Yoga is a link between a lord of one group and a lord of the other, and that is the whole definition. Dusthanas — the 6th, 8th and 12th — are the houses of difficulty, and a lord of a dusthana placed in another dusthana is the Viparita reversal. Upachayas — the 3rd, 6th, 10th and 11th — are the houses that improve with time, which is why malefics there are read differently from malefics anywhere else.

The first house belongs to two categories at once, being both a kendra and a trikona, and that is not a bookkeeping accident: it is why the ascendant lord is the single most important planet in a Parashari reading, and why a yoga involving it carries more weight than the same structure built from any other pair.

The occupants column is there because a house lord and a house occupant are different things and are constantly confused. A planet sitting in the tenth house is not the tenth lord unless it also rules the sign there. Most yoga definitions are about lords; a few — Budha-Aditya, Chandra-Mangal, the Mahapurusha set — are about occupants. The table gives you both so a definition can be checked rather than taken on trust.

1. Read the UL sign and its lord The sign is the image and the lord's placement is where the image actually operates. Both are printed above. This is the whole of what the technique computes.
2. Count the UL's house from the ascendant Its distance from the lagna is how Jaimini practice locates the marriage theme in the life. The exception rules mean it will never be in the sixth or the twelfth.
3. Compare the UL with the Arudha Lagna The AL is the public self and the UL the partnership image. Their relationship — the same sign, opposite signs, a trine apart — is a reading the tradition uses and one this page gives you both halves of.
4. Bring in the Darakaraka and the seventh house Jaimini and Parashari are separate systems and a marriage reading uses both: the UL and the Darakaraka from one, the seventh house and Venus from the other. Agreement between them is worth stating; disagreement is the honest answer that the chart is mixed.
5. Stop before the prediction The technique gives a point. Everything past that — when, whom, whether — is not in it, and the classical texts that appear to say otherwise were written in a marriage system nothing about modern life resembles.

Every combination reported above is produced by a named detector in this site's astrology engine, not by a language model and not by a lookup table of pre-written paragraphs. A detector takes the planet-to-house map, the planet-to-sign map and the ascendant, applies one classical condition, and returns three things: whether the condition held, a strength between zero and one, and the rule it applied. All three are printed.

Strength is not a score. It reflects how firmly that detector's own condition was met — how many qualifying conjunctions were found, how many of the three benefics participated, how many debilitations were cancelled. It is calibrated per detector and is not a common currency, so adding the column up produces a number that means nothing. It exists so that a marginal case can be told from an emphatic one, and for no other purpose.

Absent combinations are printed. A calculator that lists only what it found leaves a reader unable to distinguish a chart with no yogas from a check that ran incompletely, and the omission always flatters. Every page here reports the number tested alongside the number found, and both numbers come from the same list.

What is not checked is named rather than hidden. This engine has no detector for Dharma-Karmadhipati yoga — the ninth and tenth lords in conjunction or mutual aspect — so no page here claims to test it. It has none for Kaal Sarp Dosha either. Both are well-known enough that their absence looks like an oversight, which is precisely why it is stated: a row that silently reports 'not present' for a condition nothing evaluated is a lie a reader cannot detect.

The Pancha Mahapurusha set is assembled in exactly one place in the engine. It used to be detected in two modules at once, so three of the five came back twice in a single chart and Saturn's came back under two different spellings — which inflated both the count of yogas a chart carried and the scores derived from it. The count this page reports is a real count.

Almost every combination on this page is defined by house position or by house rulership, and houses are the part of a chart that moves fastest. The ascendant travels through all twelve signs every twenty-four hours — roughly one sign every two hours, and roughly one degree every four minutes — so an hour's error in a recorded birth time routinely changes the rising sign. Change the rising sign and every house lord changes with it, which changes most of the table above.

The planets themselves are far steadier. The Moon changes sign about every two and a quarter days, the Sun about every month, and Jupiter and Saturn are fixed across a whole day. So a combination defined purely by two planets sharing a sign survives a rough birth time, and one defined by houses does not. Where a result on this page depends on a house, treat it as provisional unless your birth time is recorded to the minute.

Every reading here assumes a rectified birth time. The same caution applies with more force to the divisional charts a combination should be checked against: beyond the D9 they are highly birth-time sensitive, and the D60 changes ascendant about every two minutes.

The ascendant is not a property of the instant alone. It is the point of the ecliptic rising over a particular horizon, so it is a function of the moment and of the coordinate together, and the two trade off exactly: the sky turns one degree every four minutes, and one degree of longitude is four minutes of local time. Moving one degree of longitude — about 103 km east or west at Indian latitudes — moves the ascendant a degree, and 3096 km moves it a whole sign. A different rising sign means different house lords, and every combination on this page is a statement about house lords.

Latitude matters separately and less obviously. It does not shift the clock, it changes how fast each sign climbs — the ascensional difference — so two places on the same meridian and the same instant still rise different degrees, and the gap grows the further from the equator you are. This is why a chart cast for a state capital is not a rounding of a chart cast for a village two districts away; it is a different chart that happens to look plausible.

So enter the town you were actually born in. The place search above accepts any village, town or city a geocoder knows, not a shortlist of metros, and it prints the latitude, longitude and timezone it used above the result so you can check them against a map. Since one whole sign of the ascendant is the unit this page is built from, a birth place picked for convenience damages the result in the same way and by the same mechanism as a birth time rounded to the nearest quarter hour.

The Upapada Lagna does not predict a marriage, a date, or a person. It is a computed point in a chart. Every honest use of it is comparative — between two charts, or between the UL and the rest of one — and none of them produces an event.

It does not describe a spouse's appearance, family or profession. Readings that do are taking a sign and inventing a person from it, and the same sign is the UL in roughly one chart in twelve.

A malefic near the Upapada is not a warning about a marriage. It is a chart factor, and using it to advise anybody for or against a relationship is the point at which this material stops being astrology.

Two limits apply to every page in this family and are worth stating in one place. Divisional charts beyond the D9 are highly birth-time sensitive, and every reading here assumes a rectified birth time. And nothing on this site is medical, legal or financial advice: a chart is a traditional interpretive framework, not a diagnosis, not a forecast, and never a reason to delay professional help.

A combination found in the birth chart is a first reading, not a finished one. The classical instruction is to test it against the divisional charts, and above all against the Navamsa: a yoga formed by planets that hold their dignity in the D9 is described very differently from one formed by planets that collapse there. That cross-check is the single most useful thing a reader can do with a positive result, and almost no calculator performs it.

The sixteen vargas are Parashara's Shodashavarga, and the weighting between them — Vimshopaka Bala — puts the D1, D9 and D60 highest. Every one of them is computed on this site from the classical start-sign rules rather than the cyclic shortcut that collapses the D12 and D60 into Aries. The Navamsa calculator is the one to run next after a upapada lagna check; the Shashtiamsa calculator is the final dignity test, and it needs a birth time good to the minute.

Timing is a separate system again. A natal combination is a standing feature of a chart with no dates in it; when it expresses is a Vimshottari Dasha question, read from the periods of the planets that form it. Any tool that produces a date from a natal yoga has generated a sentence rather than read a chart.
