TopToolsAiSet a countdown to any future date and time — a birthday, deadline, launch, or event — and watch it tick down live in days, hours, minutes and seconds. Set for a wedding on 25 December 2026 from today (17 September 2026), for instance, it would currently show roughly 99 days remaining, updating itself live rather than needing a manual refresh.

Frequently asked questions
Does it keep counting if I close the tab?
The countdown only runs while the page is open. Reopen it and it recalculates from the current time automatically.
Can I set it for a date years away?
Yes, there's no limit — set it for tomorrow or a decade from now.
Does it account for time zones?
It calculates based on your device's local time and date settings.
What happens when the countdown reaches zero?
It will show that the target date/time has been reached rather than continuing into negative numbers.
