Your star sign (also called your zodiac or sun sign) is determined purely by your date of birth — specifically the month and day each year, matched against fixed zodiac date ranges.

How star sign by date of birth works

Astrology tools and calculators all follow the same simple rule:
they map your birthday to one of 12 zodiac signs using pre‑set date ranges in the calendar.

Here are the commonly used Western zodiac date ranges:

  • Aries: March 21 – April 19
  • Taurus: April 20 – May 20
  • Gemini: May 21 – June 20
  • Cancer: June 21 – July 22
  • Leo: July 23 – August 22
  • Virgo: August 23 – September 22
  • Libra: September 23 – October 22
  • Scorpio: October 23 – November 21
  • Sagittarius: November 22 – December 21
  • Capricorn: December 22 – January 19
  • Aquarius: January 20 – February 18
  • Pisces: February 19 – March 20

If you tell me your date of birth (day and month), I can tell you exactly which one of these is your star sign.
