Lagna Calculator
The lagna — ascendant — is the rashi rising on the eastern horizon at your moment of birth. It sets your first house and anchors the entire kundli, which is why accurate birth time matters: lagna changes roughly every two hours.
Enter your birth details to compute your lagna sign, its degree, nakshatra and the lagna lord, using Lahiri ayanamsa. Nothing is stored.
Use this page as a quick reference whenever you need the answer — the converter above handles any value, not just the common ones, and shows the exact formula so you can verify the math yourself. All calculations happen locally in your browser: fast, private, and free with no signup.
