Countdown to a date

Create an editable countdown to an event with an exact date, time, and time zone.

Daylight-saving options
Missing clock times are always rejected.

Keep this tab available. Alarms may be delayed if the browser closes, sleeps, or suspends the page.

How to use countdown to a date

Count down to an appointment, launch, birthday, or trip. Give the event a name and choose its date and time zone. Shared links preserve the exact instant so viewers in different zones count down to the same event.

Worked example

For an event at 09:00 in Tokyo, select Asia/Tokyo and the event date. The local-time preview shows when it happens where you are.

What the result means

The event is an absolute deadline. Daylight-saving gaps are rejected; repeated clock times require an earlier or later choice.

Copy the address bar to share this countdown. A shared link opens immediately at the same finishing time, with sound off until enabled.
