Countdown Timer

This counts down live to a date and time you choose, updating every second until it hits zero. It's useful for tracking anticipation toward a future moment, an event, a deadline, a launch, with a running display of days, hours, minutes, and seconds remaining. There is nothing to install and nothing to configure beyond picking the moment you are counting down to.

How to use it

1. Select the target date and time.
2. Watch the countdown start right away, updating every second.
3. Leave the page open to keep watching it tick down.
4. Change the target anytime to start a new countdown.
5. Watch for the time's up message once it reaches zero.

When it helps

• Counting down to a product launch or an announcement.
• Tracking time left until a personal deadline, like a due date or an exam.
• Counting down to a holiday or a birthday.
• Displaying a live countdown during a stream leading up to a key moment.
• Keeping track of time before a scheduled call.

Good to know

• The countdown only runs while this page stays open. Closing the tab stops the live updating.
• Double check you've picked the right date and time, in the context of your own device's clock.
• For an event that matters across time zones, set the target using your own local equivalent.
• For an important deadline, note the target date somewhere else too, like a calendar reminder, since this timer only counts down while its page stays open.
• For a countdown you'll want to check periodically rather than watch continuously, note the target time somewhere else too, and just use this for a quick glance whenever you happen to think of it during the day.

Keeping the page open

Browsers may pause timers in background tabs to save power. For long countdowns, keep the tab visible or use a device timer for anything important.
