# Zodiac Date Ranges

Read this reference only when a person supplies a birthday instead of a star sign.

Use the month and day, ignoring the year. These fixed Western tropical ranges mirror the horoscope widget:

- 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

Reject impossible calendar dates. Clarify date order before deriving a sign from an ambiguous numeric form such as `03/04`.
