The zodiac sign — more precisely, the Sun sign — is determined by the position of the Sun on the day of birth, and in the tropical zodiac it follows fixed calendar ranges: Aries opens the astrological year in late March and Pisces closes it.
This calculator finds the sign for any date, handling the tricky boundary days and the Capricorn range that wraps across the New Year. Note that on cusp dates the sign technically depends on the exact hour and year of birth — if you were born on a boundary day, both neighboring profiles are worth reading.
Along with the sign itself you get its classical profile: the element (fire, earth, air or water), the quality (cardinal, fixed or mutable), the ruling planet and the signs traditionally considered its easiest matches, plus a short character sketch.
The lookup happens entirely in your browser and the date is never sent anywhere. Sun-sign astrology is a broad brush — treat the profile as a starting point for conversation, not a case file.
