Moon sign / Rashi calculator

Calculate an approximate sidereal Moon sign from date, time and time zone.

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 engine converts the entered local time to UTC, computes Moon longitude, subtracts Lahiri ayanamsa and divides the zodiac into twelve 30-degree signs.

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.
