After it, nights are longer than days in the northern hemisphere until the March equinox. Meteorological fall starts on September 1.

How the fall date is worked out

The date is the moment the Sun crosses the equator (an equinox) or reaches its furthest point north or south (a solstice). We calculate that moment with Jean Meeus's astronomical formulas and convert it to US Eastern time, which is why it can be a day earlier or later in other time zones. From 2026 to 2100 it falls between September 21 and September 23. How we calculate every date.

How many days until fall in weeks, weekdays and sleeps

The countdown counts calendar days from today to fall, so on the day before it shows 1. The weeks box splits that into whole weeks and days, the weekdays box counts Monday to Friday (useful for work and school planning, though public holidays are not taken out), and sleeps are the nights left. The timer counts down to midnight at the start of fall in your own time zone.
