How Many Days Until Autumn
Astronomical autumn in the northern hemisphere begins at the September equinox, around 22 September.
The clock on this page counts the days, hours and minutes left until autumn begins in the Northern Hemisphere. It is a countdown clock timer online — nothing to install, already running the moment the page opens.
- Date: Tuesday, 22 September 2026
- Counted in your local time zone — the clock above uses the time on your device.
- Next time after that: 22 September 2027
- In the southern hemisphere this season starts on 20 March 2027 — the dates are half a year apart.
When the counter reaches zero the page says «Happy Autumn!» and, the next day, starts counting to 22 September 2027.

How to use Autumn countdown
Open the page — the numbers are live immediately, no settings required. Read the count in days, hours, minutes and seconds, all ticking toward the same moment. Leave the tab open on a second screen if you like watching a season approach in real time.
Which autumn are we counting to?
Astronomical autumn begins at the September equinox, which falls on September 22 or 23 depending on the year — the target date here follows it. Meteorological autumn is simpler and earlier: it starts on September 1 and runs through November 30, because weather records prefer whole months.
South of the equator everything flips: autumn arrives in March, and this page's date belongs to spring instead. The count is honest either way — it just measures the distance to the equinox.
Why keep a countdown clock timer online
A countdown timer app wants to be installed, updated and granted permission to notify you. A page just counts. You open it when you care, close it when you don't, and it works identically on a phone, a laptop and the ancient tablet propped up in the kitchen — which, in full-screen mode, makes a perfectly good digital countdown timer.
The same clockwork runs the rest of the year, too: once autumn arrives there is Halloween to wait for, then Christmas, then the new year. Each has its own page, each counts to a fixed date without being told. Nobody ever asks summer to hurry. Autumn is the season that gets a countdown.
Do you need a countdown timer app?
Probably not. An app for countdown timer needs is worth installing when you want widgets and push notifications; for a date some weeks away, an online countdown timer in a pinned tab does the same work with less ceremony.
Search engines will count for you too — the countdown timer Google shows sits right in the results — but a result vanishes with the tab. A page with exactly one job is easier to come back to.
Questions and answers
- Why does the first day of autumn move between September 22 and 23?
- The equinox is an astronomical moment, not a calendar convention, so its date drifts slightly from year to year. The countdown follows the actual date, not a fixed one.
- Can I count down to a different date?
- Yes — the Countdowns page lists Halloween, Christmas, New Year and the other seasons, and a timer for a countdown of your own lets you set any date you like.
- Does this work on a phone?
- Yes. It is an ordinary web page, so any browser shows the same live numbers with nothing to download.
