Countdown Timer for Any Date →About the Autumn Equinox
The autumn equinox is the moment the Sun crosses the celestial equator heading south. In the north it falls on September 22 or 23, and from then until the December solstice nights are longer than days. The change shows up fast at high latitudes: in Alaska, daylight shrinks by several minutes every day around the equinox.
The first day of fall is also a cultural marker for many Americans. It lines up with the start of the school year, football season, and apple picking, and many people treat it as the official start of sweater weather. In the Southern Hemisphere, this equinox opens spring instead, while their autumn starts with the March equinox; use the switch above to count down to that one.
Meteorological fall, used by weather services for records, is September, October, and November (March through May in the south).

How Many Days Till Fall?
Look at the first tile for the days until fall; the other three narrow it down to the second. This fall countdown targets the equinox itself, the exact minute astronomers use, rather than a date picked by the calendar, so the answer can differ by a day between the West Coast and Europe.
Pumpkin patches, leaf-peeping trips, and the first chili of the season tend to cluster around the first day of fall. Keep the page open on a tablet or put it in fullscreen on the TV, and you will know exactly when the season turns.
FAQ
When does fall start?
Astronomical fall begins at the September equinox, which in 2027 comes at 6:01 AM UTC on Thursday, September 23, 2027. In the Southern Hemisphere, the same moment marks the start of spring.
When does autumn start?
At the same moment as fall. The first day of autumn and the first day of fall are one date, because the two words are synonyms: Americans mostly say fall, while British and Australian English prefer autumn. Meteorological autumn starts earlier, on September 1 in the north and March 1 in the south.
Are day and night equal on the autumn equinox?
Almost, but not exactly. Sunlight bends in the atmosphere and the Sun is a disk rather than a point, so most places get a few minutes more day than night. The date of truly equal day and night, sometimes called the equilux, comes a few days after the September equinox.
