How Many Days Until Fall 2027?

When is Fall? Dates for 2027–2031

Rule: September equinox, usually September 22–23 in the US. Years marked approx. use the usual calendar date; the exact equinox or solstice can be a day earlier or later.

How the date of Fall is set

Astronomical fall (autumn) starts at the September equinox, when the Sun crosses the celestial equator heading south. The countdown runs to the exact moment published by the U.S. Naval Observatory; dates are shown in US Eastern Time. Meteorological fall starts September 1.

How the countdown is counted

The big number counts calendar days from today, not counting today, so the day before Fall shows 1 day. The live clock counts down to the exact astronomical moment in your time zone, which is why it can show one day fewer plus some hours. As of Monday, October 26, 2026, 332 days remain, of which 238 are weekdays (Monday to Friday, public holidays not removed). To count down to a birthday, a trip or any other date, or to count the days since a past date, use the Days Until Calculator.
