Upapada Lagna Calculator (Jaimini)उपपद लग्न

The upapada lagna is a point in the Jaimini system of Vedic astrology: the arudha pada of the 12th house, written A12. Classical sources — the Jaimini Sutras and the Jaimini chapters of Brihat Parashara Hora Shastra — examine the UL, its lord and the signs around it for marriage and the spouse. It is a sign, not a planet: this calculator reports which of the 12 signs your UL falls in and which planet rules that sign.

By the standard arudha rule applied to the 12th house: find the lord of the 12th sign from the lagna, count how many signs it has travelled from the 12th, then count that same distance again from the lord — the sign you land on is the arudha. Classical exceptions apply when the count lands in the same sign or the 7th from it (the pada is then moved 10 signs forward). This tool computes it from your birth chart automatically, using Swiss Ephemeris positions with the Lahiri ayanamsa and whole-sign counting.

No — they are different points built by the same rule. The arudha lagna (AL, or A1) is the arudha pada of the 1st house and is read for the person's worldly image; the upapada lagna (UL, or A12) is the arudha pada of the 12th house and is read for marriage and the spouse. This calculator shows both, along with the arudha padas of all twelve houses (A1 through A12).

In classical Jaimini reading the UL and its lord describe the marriage and the spouse's circumstances: the texts read the UL's sign and lord for the nature of the union, and the 2nd sign from the UL for the sustenance of the marriage. It is always weighed together with the darakaraka (the spouse significator among the charakarakas) and the navamsa — no single point is treated as a verdict on anyone's marriage.

The charakarakas ('movable significators') are the Jaimini system's way of assigning life roles to planets by rank: the planets are ordered by how many degrees each has travelled within its sign. The highest-degree planet is the atmakaraka (AK, the self/soul); then follow amatyakaraka (AmK, career), bhratrikaraka (BK, siblings/guru), matrikaraka (MK, mother), pitrikaraka (PiK, father), putrakaraka (PK, children), gnatikaraka (GK, obstacles/rivals) and darakaraka (DK, spouse) — the lowest degree. This calculator lists all eight for your chart, computed in the eight-karaka scheme.

The karakamsha is the navamsa (D9) sign occupied by your atmakaraka — take the highest-degree planet in the chart and see which sign it falls in within the ninth divisional chart. Jaimini reading uses the karakamsha as an anchor for the direction of the person's life and inclinations, reading houses counted from it. This calculator reports your karakamsha sign with its classical citation.

Because Jaimini computation has genuine school-to-school variations (choice of karaka scheme, arudha exceptions), every statement in the result carries its source — book and line — from the classical corpus the engine implements. That lets you check the rule behind each value instead of taking the output on faith, and it makes clear which convention was applied where traditions differ.
