Sun sign calculator

Find both tropical and sidereal Sun signs at your birth time.

Choose the time zone of the birthplace, not your current location. If the birth time is unknown, a sign or Nakshatra near a boundary may be uncertain.

How this works

The tropical zodiac starts at the equinox; the sidereal zodiac subtracts Lahiri ayanamsa. They are different systems, so both are labelled.

Approximate geocentric Sun/Moon calculations using the existing Meeus-based engine and a linear Lahiri ayanamsa. Near sign/Nakshatra boundaries, verify with a precise ephemeris. This is not a full Kundli.
