Find your Upapada Lagna (UL), the Jaimini marriage pada, from your date, time, and place of birth. This calculator shows how the pada is derived step by step - your 12th house, its lord, and the two-step count - applies the classical 1st/7th exception transparently, and flags how close your birth time sits to a rising-sign boundary, using sidereal Lahiri ayanamsa.
100% private - the Upapada calculation runs entirely in your browser. No birth data sent anywhere.
Supports 1900 onwards for better calculation reliability.
Birth time matters here: the Upapada hangs off your rising sign, which changes about every 2 hours but can flip with a few minutes' error if you were born near a sign boundary - the tool flags how close you are.

The Upapada Lagna (UL) is a point from Jaimini astrology: the arudha pada of the 12th house. An arudha pada is the 'reflection' or projected image of a house - what the house shows to the world rather than its literal meaning. Sanjay Rath calls the Upapada the Vivaha Mandapa, the marriage altar, the reflection of the 12th house of the bed and the loss of one's single state.
Classically the Upapada is read for marriage as a social institution and for the spouse and the character of the long-term partnership. P.V.R. Narasimha Rao states plainly that the Upapada 'shows one's marriage and spouse'. Like every arudha, it is a descriptive lens on the chart, not a prediction and not a verdict.
Take the 12th house from your ascendant and find its lord. Count - inclusively, in zodiac order - from the 12th house to the sign the lord occupies. Then count that same number of signs forward again, starting from the lord's sign. The sign you land on is the raw pada. This is the identical two-step count used for the Arudha Lagna, applied to the 12th house instead of the 1st.
One classical rule modifies it: the pada is not allowed to rest in the house's own sign (the 1st) or in the 7th from it. When the count lands in either, the pada is moved to the 10th sign from that raw pada - so a landing in the 12th house's own sign becomes the 10th from there, and a landing in the 7th becomes the 4th from the house. This calculator applies the exception by default and always shows the raw, pre-exception pada as well, so you can see exactly what was redirected.
Worked example (from Narasimha Rao's textbook): if the 12th house is Leo and its lord the Sun sits in Pisces, count inclusively from Leo to Pisces (eight signs), then eight signs on from Pisces, landing on Libra - the Upapada Lagna. The tool does this counting for you and names the lord and its sign so you can follow each step.
By a classical rule the arudha pada cannot fall in the house's own sign or the 7th from it - Rath frames this as the Satya principle, that the truth (the 1st and 7th, the Brahma and Shiva points) cannot be the same as its own reflection (maya). When the raw count lands there, the pada is redirected to the 10th sign from that raw pada. This is stated in the Brihat Parashara Hora Shastra (Chapter 29, Bhava Padas, Santhanam edition, page 235, verses 4 to 5) and in the Jaimini Upadesa Sutras (Chapter 1, sutras 31 to 32).
It is not fully unanimous: a documented minority view applies the count without the exception. This tool applies the exception by default but always surfaces the raw pre-exception pada, so a reader who follows the no-exception school can still see the raw value.
This calculator uses strict-classical lordship: Scorpio is ruled by Mars and Aquarius by Saturn, and the lunar nodes Rahu and Ketu are never treated as sign lords. Both P.V.R. Narasimha Rao and Sanjay Rath instead take the stronger of the two co-lords (Ketu for Scorpio, Rahu for Aquarius) when that node is judged stronger, which can change the Upapada Lagna for a Sagittarius or Pisces ascendant, whose 12th house is Scorpio or Aquarius. That needs a planetary-strength model this tool does not compute, so the stronger-co-lord school is disclosed here but not applied.
In practice this only affects a Sagittarius ascendant (12th house Scorpio) or a Pisces ascendant (12th house Aquarius), and only when the node would be judged the stronger co-lord. For every other ascendant the 12th lord is unambiguous and the two schools agree. If you follow the stronger-co-lord method, treat the Upapada shown here as the strict-classical reading and recompute by hand for those two ascendants.
These are four different things and are easily confused. The Arudha Lagna (A1) is the arudha of the 1st house - your projected public image. The Upapada Lagna (A12) is the arudha of the 12th - the marriage pada. The Dara Pada (A7) is the arudha of the 7th, a separate partner-image pada. The Darakaraka is something else again: not an arudha at all, but the planet with the lowest longitude among the seven chara karakas, the Jaimini significator of the spouse.
For the full set of all twelve arudha padas, use the Arudha Lagna calculator; for the Darakaraka and the rest of the chara-karaka ladder, use the Chara Karaka calculator. This page focuses on the Upapada and the points read directly with it.
Yes, birth time matters. The Upapada is built on the 12th house, and the houses are anchored to your rising sign, which changes roughly every two hours. If you were born within a few minutes of a sign boundary, even a small error in the recorded time can flip the rising sign and move the Upapada with it. The tool reports how many minutes you are from the nearest rising-sign boundary and, when you are close, what the Upapada would be under the adjacent rising sign.
The engine uses Meeus-based VSOP87 with the sidereal Lahiri ayanamsa, typically within about 0.3 degrees of observatory-grade ephemerides for dates from 1900 onwards. One honest limit: this version flags the rising-sign boundary only, not a house lord sitting right on a sign edge, which can shift the pada on its own - so if a key planet is near a boundary, treat the pada as provisional.
The Upapada Lagna is the arudha pada of the 12th house in Jaimini astrology, read for marriage as a social bond and for the spouse and partnership. It is computed by counting from the 12th house to its lord and then the same distance again from the lord, with the classical 1st/7th exception applied. It is a descriptive perspective on the chart, not a prediction.
They are computed the same way but from different houses. The Arudha Lagna is the arudha of the 1st house and stands for your projected public image. The Upapada Lagna is the arudha of the 12th house and is read for marriage and the spouse. Every chart has both, along with the arudha padas of the other ten houses.
In the mainstream method used by Sanjay Rath and P.V.R. Narasimha Rao, yes - the Upapada is the arudha pada of the 12th. A few older writers describe variant schemes for odd versus even ascendants, but they are not widely followed; this calculator uses the standard arudha-of-the-12th method and does not implement the variants.
By a classical rule the arudha pada cannot fall in the house's own sign or the 7th from it. When the raw count lands there, the pada is redirected to the 10th sign from that raw pada. This tool applies the exception by default, per BPHS Chapter 29 and the Jaimini Upadesa Sutras, and always shows the raw pre-exception pada so you can see what was redirected.
No. The Upapada Lagna is a descriptive lens on marriage and partnership in the classical framework. It does not predict when you will marry, whether you will marry, or what a spouse will look like or be named, and this tool prescribes no remedy. Any such reading should come from a qualified astrologer, and even then is interpretive, not deterministic.
This calculator uses strict-classical lordship, where the lunar nodes are never sign lords, so Scorpio's lord is Mars and Aquarius's is Saturn. Both Narasimha Rao and Sanjay Rath instead use the stronger of the two co-lords (Ketu for Scorpio, Rahu for Aquarius) when the node is stronger, which can change the Upapada for a Sagittarius or Pisces ascendant. That needs a planetary-strength model we do not compute, so it is disclosed but not applied.
In the Jaimini tradition the 2nd house from the Upapada is read for the sustenance or continuity of the marriage. This tool shows that sign for reference only and offers no verdict on it. Note that this is the 2nd from the Upapada; in Sanjay Rath's school the label 'UL2' means a different point, the 8th from the Upapada, which this tool does not compute.
This page is the canonical surface for these terms: Upapada Lagna, Upapada, Upapada Lagna calculator (including the online free and by-date-of-birth variants), UL calculator, marriage pada, and the arudha of the 12th house. They all refer to the Jaimini pada described above.
