September Zodiac Sign: Virgo or Libra?
The September zodiac signs are Virgo (approximately September 1–22) and Libra (approximately September 23–30). Birthdays near the change need a calculation using the birth year and time.
Libra starts at the September equinox in the tropical zodiac. The timing of that event explains why fixed date lists sometimes disagree.

September 22 or 23: Virgo or Libra?
The tropical Sun enters Libra at the September equinox. That occurs at a specific time, with a local date that depends on year and time zone. A guide that starts Libra on September 23 is giving a convention, not a universal cutoff. Birthdays around September 22–24 should be checked with a calculated chart.
Check your Sun sign with your birth details
Our free birth-chart calculator uses your full birth date, local birth time, and birthplace. If you do not know the time and were born near the sign change, treat the Sun-sign result as uncertain. Choosing a default time cannot settle a boundary birthday.
Calculate your birth chartSeptember’s equinox is not autumn everywhere
The September equinox begins astronomical autumn in the Northern Hemisphere and spring in the Southern Hemisphere. Libra’s tropical starting point refers to the same moment worldwide. Descriptions based on autumn imagery are cultural interpretations, not a reason to assign Southern Hemisphere births to another sign.
