Upapada Lagna Calculator — Spouse & Marriage from your Vedic Chart
What is the Upapada Lagna (UL) in Vedic astrology?
The Upapada Lagna — UL, also written A12 — is a special lagna from Jaimini astrology. It is the Arudha Pada of the 12th house, and it is the single most important pointer to marriage, the spouse and committed partnerships in the chart.
How it is calculated
An Arudha Pada is found by counting from a house to its lord, then counting the same number of signs again from the lord. For the Upapada Lagna we start from the 12th house. A classical exception applies: if the result falls in the same sign as the house or the 7th from it, the 10th sign from that point is taken instead.
What the Upapada Lagna shows
- The UL sign describes the nature, looks and temperament of your spouse.
- The UL lord and the house it sits in show where the marriage plays out in your life.
- The 2nd house from UL shows the sustenance and longevity of the marriage — benefics here support a lasting bond, malefics ask for care.
- Planets in and aspecting the UL colour the relationship — benefics bless it, malefics bring lessons to grow through.
This calculator computes the Upapada Lagna from your sidereal (Lahiri) chart and reads each of these factors, with a downloadable PDF. It is an educational guide — a complete marriage reading also weighs the 7th house, Venus and the Navamsa (D9).

Do I need my exact birth time for Upapada Lagna?
Yes for a reliable reading. Upapada Lagna depends on the ascendant and house lords, which shift with the birth time — so enter the exact time with the correct AM/PM and pick your city from the suggestions. A rough time can still give a broad sense, but house-based results may change.
