What is lagna (the ascendant) in astrology?

The short answerThe lagna (ascendant) is the sign rising on the eastern horizon at the moment and place of your birth. It becomes your 1st house, and every other house is counted from it, so it frames the whole chart. It changes every one to three hours: in Delhi between 85 minutes and 2 hours 21 minutes per sign; in London between 51 minutes and nearly 3 hours. That is why the birth time matters so much.

1. What the lagna is

As the Earth turns, each of the twelve signs rises in the east in turn. The one rising at your birth is your lagna, and the exact degree rising is the ascendant degree. In English it is called the ascendant or rising sign.

2. What it shows

3. Why it changes at different speeds

Signs don’t all rise at the same speed. Near the tropics the difference is modest; further north it is large. For 15 January 2027:

51 minis all the time Pisces takes to rise over London. A birth-time error of 20 minutes there can change the lagna.Our calculation of the ascendant minute by minute for London and New Delhi, 15 January 2027.

4. How to find yours

You need your birth date, the most accurate time you have, and the place. If your lagna is near the start or end of a sign, our calculator warns you how many minutes away the change is, so you can judge how sure to be.

Worked example: Albert Einstein

Born at 11:30 local mean time in Ulm, Einstein had Gemini rising at 19°28′, in the nakshatra Ardra, pada 4. His lagna lord is Mercury, placed in the 10th house: the planet of thought ruling the chart and sitting in the house of work. His navamsa ascendant is Pisces.

5. If you don’t know your birth time

Without a time the lagna and houses are unknown. The Moon sign still works for horoscopes and most matching; astrologers then read the chart from the Moon (the chandra lagna).
