Ascendant Calculator
The ascendant is the zodiac sign rising on the eastern horizon when you were born — called lagna in Vedic astrology. It fixes your first house and the layout of the whole birth chart, and it changes roughly every two hours, so birth time accuracy is essential.
Enter your birth date, time and city to get your sidereal ascendant sign, degree, nakshatra and lagna lord, computed with Lahiri ayanamsa.
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.
