About the result
What is Lagna in a birth chart?
Lagna, or the sidereal Ascendant, is the zodiac degree rising on the eastern horizon at the exact time and place of birth. Its rashi becomes the first house of the Kundli.
Why time matters
The Ascendant moves through the zodiac throughout the day, so an approximate birth time can change its degree and may change the Lagna rashi near a boundary.
Why place matters
Latitude and longitude define the local horizon. The same instant can therefore have a different rising degree in another city.
Sidereal result
The calculator converts the local civil time to UTC, finds the tropical horizon, and applies Lahiri ayanamsa to return the sidereal Lagna.
