How to use Zodiac Sign Calculator
Choose your date of birth; add the time and UTC offset if you were born on the day the sign changes. Switch between the Western and the Vedic zodiac.
How it works
The sun’s ecliptic longitude at birth is computed (Meeus, about 0.01° accuracy); each sign covers 30°. The Vedic option subtracts the Lahiri ayanamsa (about 24.2° in 2026).
Example
Born on 14 August 1995, the sun was at 21° Leo: a fire sign, fixed, ruled by the Sun. In the Vedic zodiac the same date is Karka (Cancer).
