Our fall countdown timer shows exactly how many days, hours, minutes, and seconds until the first day of fall on Tuesday, September 22, 2026. The autumnal equinox marks the official start of fall in the Northern Hemisphere!
The fall equinox (also called the autumnal equinox) occurs when the sun crosses the celestial equator moving southward. On this day, daylight and nighttime are nearly equal in length. It marks the astronomical beginning of autumn and signals the transition to shorter days and cooler temperatures.
Fall is packed with beloved holidays and traditions. From Halloween and Thanksgiving to Oktoberfest and harvest festivals, autumn offers plenty of reasons to celebrate. Many cultures mark the equinox with harvest celebrations giving thanks for the year's bounty.
