How the date of the first day of fall is set
Astronomical fall (autumn) in the Northern Hemisphere begins at the September equinox, which falls on September 22 or 23 in most years.
The US Naval Observatory publishes the equinox and solstice times. The times on this page are calculated with Jean Meeus's method and agree with them to within a minute or two.
Also coming up: the first day of winter on Monday, December 21, 2026, Halloween on Saturday, October 31, 2026, and Thanksgiving on Thursday, November 26, 2026.
September equinox facts
At the September equinox the Sun crosses the celestial equator heading south. From then until March, nights are longer than days in the Northern Hemisphere.
At the September equinox, seen from the equator, the Sun rises due east and sets due west. Because the calendar year and the solar year differ slightly, the equinox can fall anywhere from September 21 to 24.
- Meteorologists count fall from September 1 instead.
- In the Southern Hemisphere the September equinox is the start of spring.
