About this tool
The Countdown Timer counts down to any date and time you choose — a deadline, an event, a launch — showing days, hours, minutes, and seconds remaining, updating live every second. Give it a label to remember what you're counting down to. Everything runs in your browser using your device's clock; nothing is sent to a server.
Frequently Asked Questions
Does the countdown keep running if I leave the page open?
Yes, as long as the tab stays open — it updates every second using your device's clock. If you close the tab or navigate away, the countdown itself isn't saved anywhere; you'll need to re-enter the target date when you come back.
What time zone is the target date in?
Whatever your device's local time zone is set to — the date and time you pick are interpreted in your own local time, and the countdown is calculated against your device's current local time.
What happens when the countdown reaches zero?
It shows a 'Time's up!' message instead of a negative countdown.
