About Fall
Astronomical fall begins at the September equinox, a precise instant when the Sun reaches 180° of ecliptic longitude. In 2027 that instant is September 23 at 06:02 UTC. The countdown above runs to that moment and shows its date in your time zone, which can be a day earlier in the Americas when the instant falls in the first hours of the UTC day.
The September equinox falls on September 22 and September 23 in the coming ten years. It drifts by about six hours a year and jumps back after each leap day, which is what keeps it close to the same date. The times are the US Naval Observatory’s published times, to the minute, in UTC.
Meteorologists use whole months instead: meteorological autumn starts on September 1, which makes seasonal statistics easier to compare. In the Southern Hemisphere the seasons are reversed: the September equinox begins spring in Australia, New Zealand, South Africa and Argentina.
How the countdown works
The countdown runs to the exact instant of the event and shows its date in your time zone. It uses your device’s time zone and our server-corrected clock, so it stays right even if your device clock is a few seconds off. The day after Fall, the page moves on to the next year’s date by itself.
“Sleeps” is the number of nights left, the way children count: on the evening before the day it is one sleep.
