Calendar
Enter a birth date to find its Western zodiac sign, using the standard tropical date ranges.
The tropical zodiac's sign boundaries were fixed relative to the seasons roughly 2,000 years ago and haven't been updated since, so different sources round the cusp dates slightly differently (some list Aries as starting March 20, others March 21). This tool uses the most commonly cited standard ranges — if your birth date falls exactly on a boundary day, some sources may place you in the adjacent sign instead.
This calculates the tropical zodiac used in most Western horoscopes — the one tied to the seasons. Vedic (sidereal) astrology, used in Indian astrology, uses a different system tied to the actual current position of constellations, which shifts the same birth date into a different sign roughly three weeks earlier on average due to axial precession.
