Quick answers to common questions
Western zodiac signs are determined purely by birth date, based on fixed calendar date ranges established by tropical astrology (e.g., Aries: March 21 - April 19). Unlike some astrological calculations, this is a simple date-range lookup with no ambiguity or need for birth time.
Cusp dates (the 1-2 days at a sign's boundary) can vary by 1 day between sources depending on which year's exact solar transit dates they use, since the Sun's position shifts very slightly year to year. This calculator uses the most commonly cited standard date ranges.
Your zodiac (sun) sign is based only on birth date. Your moon sign requires your exact birth TIME and LOCATION, since the Moon moves through signs much faster (changing roughly every 2-3 days) and needs precise astronomical calculation. This tool covers sun signs only — moon sign calculation needs a proper astrology service with ephemeris data.
