When is the first day of fall?
Fall starts at the September equinox, when the Sun crosses the equator heading south and stands directly overhead there at noon. In 2027 that happens at 2:01 AM EDT on Thursday, September 23, 2027, which is 06:01 UTC on September 23, 2027.
In Eastern Time the equinox falls on September 22 in most years. It lands on September 23 in 2027, 2031 and 2035, then not again this century, and September 21 starts to appear in 2072. Across the country the date can split. The 2027 equinox falls on September 23 in New York, but at 11:01 PM PDT on September 22 in Los Angeles.
Meteorological fall: September 1 to November 30
Weather records group September, October and November as fall, 91 days that start on the same date every year. Astronomical fall starts about three weeks later and runs to the December solstice, so the end date and length under the clock come from that solstice instead.
Fall and the November clock change
Clocks fall back on the first Sunday in November, inside astronomical fall every year. In Eastern Time that Sunday comes 39 to 47 days after the September equinox. At 2:00 AM clocks go back to 1:00 AM, so sunrise and sunset both jump an hour earlier on the clock, on top of the daylight fall is already losing. The end of daylight saving time has its own countdown.
Nights overtake days within a few days after the equinox and stay longer until spring. Before winter arrives, the Halloween countdown runs to October 31 and the countdown to winter runs to the December solstice. For a trip or a deadline, count the days until any date.
Frequently asked questions
Is the first day of autumn the same as the first day of fall?
Yes. Fall and autumn are two names for the same season, and both are standard American English. Each starts at the September equinox.
