Countdown Timer
Set a date and time, or pick a quick preset. The countdown keeps real time and lets you know when it reaches zero.
- Runs in your browser
- Keeps time in background tabs
What are you counting down to?
Your countdown
Ready
Your event
No date selected yet.
Set your event and press “Start countdown”, or pick a preset.
How it works
Real clock time, worked out fresh every moment.
- Target
- Your date and time, read in your device’s time zone. If you leave the time empty it counts to midnight (00:00).
- Presets
- Start immediately and count down exactly 10 minutes, 30 minutes, 1 hour or 24 hours from the moment you press them.
- Days
- A day is 24 hours of real time. Across a clock change, “tomorrow at the same time” may show as 23 or 25 hours.
- At zero
- The timer shows “Done!”, plays a short chime if the sound is on and shows a notification if you allowed it.
Questions
Does it keep counting in a background tab?
Yes. The countdown is worked out from the real clock, not by counting ticks, so it stays right even when your browser slows down background tabs or your computer sleeps. If you turn on the sound or a notification, you’ll be told when it reaches zero.
Can I share a countdown?
Yes. Press Share to copy a link. Anyone who opens it sees the same countdown to the same moment, shown in their own time zone. The event name isn’t included in the link.
Which time zone is used?
The date and time you pick are read in your device’s time zone. The countdown itself is to an exact moment, so people elsewhere count down to the same instant.
Will it survive a refresh?
Yes, while the countdown’s link is in the address bar: the page reads the target time from the link and carries on. The event name isn’t kept in the address, so after a refresh the countdown shows “your event” until you type the name again. Nothing is saved on your device, so closing the tab without the link ends it.
Will I get a notification?
Only if you switch “Show a notification” on and allow notifications when your browser asks. The sound at zero is on by default and can be switched off.
