Countdown Timer

Count down the days, hours, minutes and seconds to any date and time, live. Set an event name and share the countdown with a link.

How to use the countdown Timer

  1. Enter the event name.
  2. Pick the date and time.
  3. The result refreshes every second, so you can leave the page open.
  4. Use Copy result to copy the figures, or Copy link to share a link that reopens the countdown Timer with the same inputs.

How it works

A countdown makes a date feel real, whether it is a holiday, a product launch, an exam, a wedding, a birthday or a retirement. This timer shows exactly how long is left in days, hours, minutes and seconds, updating every second while the page is open. It also gives the total in single units, which is handy for "sleeps until…" or "hours until…" questions.

The target is interpreted in your device's local time zone, and the timer compares it with your device's clock. If the date is on the other side of a daylight saving change, the countdown accounts for the extra or missing hour automatically. Once the moment has passed, the timer keeps going and counts the time since.

To share a countdown, give the event a name, set the date and time, then press Copy link. Anyone who opens the link sees the same event and target time. Note that the time is read in each viewer's own time zone, so for an event in a specific city, such as a live stream, use the time zone converter to agree on the time first.

Formula

remaining = target − now (in milliseconds) days = ⌊remaining / 86,400,000⌋ hours = ⌊(remaining mod 1 day) / 3,600,000⌋ minutes = ⌊(remaining mod 1 hour) / 60,000⌋ seconds = ⌊(remaining mod 1 minute) / 1,000⌋

Example

At 9:30 am on December 1, a countdown to midnight on December 25 shows 23d 14h 30m 00s: 23 full days take you to 9:30 am on December 24, and 14 hours 30 minutes more reach midnight. That is about 23.6 days, 566 hours or 33,990 minutes.

Frequently asked questions

Does the countdown keep running if I close the page?

The target date is saved in the link, not on a server. When you reopen the page or the link, it recalculates from the current time, so it is always correct.

Which time zone does it use?

Your device's local time zone. Someone in another time zone who opens your link will see the target at the same clock time in their own zone.

Can I count up from a past date?

Yes. Enter a date in the past and the timer shows how much time has passed since then.
