How Many Days Until Fall?

Fall 2026 starts on Tuesday, September 22, 2026. The live clock above counts down the remaining days, hours, minutes, and seconds until the Autumnal Equinox.

Fall, also referred to as autumn, brings cooler weather, changing foliage, and the harvesting of crops as the Earth transitions from the warmth of summer toward winter.

What Is the Autumnal Equinox?

The Autumnal Equinox is the moment when the sun crosses the celestial equator from north to south. On the day of the equinox, day and night are of almost equal duration (12 hours each) all over the globe.

Following the equinox, the Northern Hemisphere tilts away from the sun, causing days to become shorter and nights longer until the winter solstice arrives in December.

Here is when the Autumnal Equinox occurs over the next few years:

Astronomical vs. Meteorological Fall

Astronomical fall begins on the autumnal equinox (September 22 or 23) and ends on the winter solstice (December 21 or 22).

Meteorological fall is determined by calendar months. It begins on September 1 and ends on November 30, encompassing September, October, and November. This calendar alignment simplifies seasonal record-keeping.
