Lagna Calculator
What is the Lagna?
The Lagna (Ascendant) is the zodiac sign rising on the eastern horizon at the moment of birth. It forms the 1st house of the Kundli, and every other house is counted from it.
Because a new sign rises roughly every two hours, the Lagna is the most time-sensitive part of the chart.

Accuracy
Positions are computed with the JPL DE421 ephemeris and the Lahiri ayanamsa, accurate to roughly an arcminute. A planet sitting within an arcminute of a sign or nakshatra boundary can land on the other side of it, so treat borderline results as a starting point for an astrologer, not a final word.
