Free Lagna (Ascendant) Calculator
The lagna is the zodiac sign rising on the eastern horizon at your exact moment and place of birth. It fixes the twelve houses of your kundli and is the most time-sensitive point in your chart.
The ascendant moves through the entire zodiac every day — roughly one sign every two hours — so even a few minutes of birth-time error can change your lagna. This is why serious astrologers insist on an accurate birth time.
Your lagna sign and its lord shape your physical constitution, temperament and the house framework everything else is read from. Panch Mahapurusha yogas, house lordships and dasha interpretations all start from the lagna.
We compute the ascendant from your geographic coordinates and the sidereal time of your birth with the KundliNow Ephemeris, Lahiri ayanamsa applied — and show the exact degree, not just the sign.
FAQ
How fast does the lagna change?
It moves about 1° every four minutes, completing a sign in roughly two hours (varying with latitude and season). A 10-minute error in birth time shifts the ascendant by ~2.5°, which can flip the sign near a boundary.
Can I know my lagna without birth time?
No — the lagna depends entirely on the exact time and place. Without it, astrologers use the Moon chart (chandra lagna) instead, which our free kundli also provides.
What is the difference between lagna and rashi?
Rashi is the Moon’s sign at birth; lagna is the sign rising on the horizon. The lagna sets the houses; the rashi drives dashas, rashifal and matching.
