Countdown Timer
Enter a target date and time to see a live countdown in days, hours, minutes, and seconds — perfect for tracking an upcoming event, deadline, or celebration.
How to use the Countdown Timer
Optionally name your event, then pick a target date and time, and click "Start countdown." A live counter updates every second, showing exactly how many days, hours, minutes, and seconds remain until that moment.
Common uses for a countdown timer
Countdown timers are popular for tracking time until weddings, exams, product launches, holidays, birthdays, or any deadline you want to keep visible. Watching the numbers tick down in real time makes upcoming events feel more tangible than just checking a calendar.
Frequently asked questions
Does the countdown keep running if I leave the page open?
Yes, as long as the page stays open in your browser tab, the countdown updates live every second. If you close the tab, you'll need to re-enter the date when you come back — this tool doesn't save data between visits.
What happens when the countdown reaches zero?
The timer will show that the target date and time has arrived, letting you know the countdown is complete.
Is my data stored anywhere?
No. This tool is part of the Toolyard collection of free, browser-based utilities. The countdown runs locally in your browser — nothing you enter is uploaded to or stored on a server.
