How Zodiac Signs Are Determined
Western astrology divides the calendar year into twelve roughly month-long segments, each associated with a zodiac sign based on where the sun appeared to be positioned relative to the twelve constellations of the zodiac in ancient times. Your sign is simply determined by which date range your birthday falls into.

Frequently Asked Questions
Each Western zodiac sign is assigned to a fixed date range on the calendar, based on the sun's traditional position relative to the twelve zodiac constellations. Your sign is simply whichever date range contains your birthday.
The date ranges shown here follow the most common Western astrology convention, but some sources shift cusp boundaries by a day depending on the year and time zone. If your birthday falls exactly on a boundary date, different sources may classify you slightly differently.
The Western (tropical) zodiac used here assigns a sign based on your birth month and day. The Chinese zodiac is a completely different, year-based system that assigns one of twelve animal signs based on your birth year (following the lunar calendar). This calculator does not calculate the Chinese zodiac.
No — this tool is for entertainment purposes only. Zodiac signs are not scientifically validated predictors of personality traits or life events; the personality descriptions here are general and traditional, not factual claims.
Traditional astrology groups the twelve signs into four elements — Fire, Earth, Air, and Water — each associated in folklore with a general temperament (for example, Fire signs are traditionally described as energetic). This is a traditional classification, not a scientific one.
