Choose a date to start the countdown.
How the countdown is calculated
The countdown measures the real elapsed time between now and your target moment, in your own time zone. It updates every second and handles the awkward cases automatically: leap years, months of different lengths, and daylight saving changes are all absorbed because the calculation works on actual timestamps rather than counting calendar squares. If the date has already passed, it counts up instead of showing a negative number.
A note on time zones
The countdown runs in the time zone of the device viewing it. That is usually what you want — a countdown to midnight on New Year's Eve should hit zero at midnight wherever you are.
It does mean that a shared link behaves slightly differently for someone in another country. If you are counting down to a specific global moment, such as a product launch or a live broadcast, say the time zone in the countdown's name so there is no ambiguity.
What people count down to
The most-searched countdowns follow a predictable rhythm through the year, but the useful ones tend to be personal.
- Exams and deadlines — seeing days rather than weeks tends to concentrate the mind usefully.
- Weddings and holidays — a shared link is an easy thing to send round a group.
- Launches and go-lives — pair the countdown name with an explicit time zone.
- Milestones — a due date, a retirement, the end of a contract.

- Give your countdown a name — this appears in the label and in the shared link.

Frequently asked questions
Does the countdown keep running if I close the page?
The display stops, but nothing is lost. Reopening the shared link recreates the same countdown, because the date is stored in the link rather than on a server.
Can I share a countdown with someone?
Yes. Press "Copy shareable link" and send it. The date, time and name travel in the URL, so anyone who opens it sees the same countdown running in their own time zone.
What happens after the date passes?
It counts up instead, showing how long ago the moment was. This is handy for anniversaries and "days since" milestones.
Does it handle leap years and daylight saving?
Yes. The countdown works on real timestamps rather than calendar arithmetic, so leap days and clock changes are accounted for automatically.
Is my countdown stored anywhere?
No. Everything lives in the page URL and in your browser. Nothing is sent to a server.
