Your Western zodiac (sun) sign is determined by the position of the Sun on the day you were born. There are twelve signs — Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces — each spanning about a month and each linked to one of four elements (Fire, Earth, Air, Water) and a quality (Cardinal, Fixed or Mutable).
Astrology is a centuries-old tradition enjoyed worldwide as a fun lens for personality, compatibility and self-reflection. This calculator instantly maps your birthday to the right sign and summarises the traits it's traditionally associated with — perfect for comparing with friends, partners and crushes.
Western astrological signs are determined by date ranges corresponding to the twelve segments of the tropical zodiac, each about 30 degrees of the ecliptic. The system was fixed roughly two thousand years ago and has not been updated since, while the Earth's axis precesses in a 26,000-year cycle — so the constellations have drifted about one full sign relative to the dates. Someone described as Aries by the tropical system typically has the Sun in Pisces astronomically. Astrology has no demonstrated predictive validity in controlled studies; this is a date-range lookup for entertainment, not a scientific instrument.

Assumptions: For entertainment. Astrology has been tested repeatedly in controlled studies and shows no predictive validity. Sidereal astrology, used in Vedic tradition, applies different dates because it does account for precession.

The gap between the tropical dates and the actual constellations is about one sign, a consequence of precession since the system was codified. Both facts can be stated plainly: the date ranges are what the tradition uses, and the tradition has no measured predictive power.
