Countdown Timer
Pick a target date and time and watch a live countdown in days, hours, minutes and seconds, updating every second. It also shows the gap in weeks and days, and counts up if the date has already passed.
Target date & time
What is it? (optional)
Pick a date and time above to start the countdown.
The countdown uses your device's clock and time zone and updates every second while this page is open. Nothing is saved or uploaded.
FAQ
- Does it keep running if I close the tab?
- No — it's a live view, not a saved timer. It recalculates from your device clock each time you open the page.
- Which time zone does it use?
- Your device's local time zone. The target you enter is treated as local time.
