What a 10 second timer is good for
- Final countdowns. Count down the last ten seconds before midnight on New Year's Eve, a launch or the start of a race.
- Quick-fire answers. Give each player ten seconds to answer in a classroom quiz or party game.
- Word warm-ups. Name as many things in a category as you can before the alarm — a common warm-up in language classes.
- Short pauses. Time a brief pause between exercises or repetitions.

About this timer
The countdown runs against your device's clock from the moment you press Start, so it stays accurate in a background tab. The line under the digits shows the local time it will end. Pick one of ten alarm sounds, all generated in your browser (hear them on the countdown sounds page), and use full screen to read the time from across a room. Need a different length? Set a custom timer.

Frequently asked questions
How do I set a timer for 10 seconds?
This page is already set to 10 seconds. Press Start, or the Space bar, and the countdown begins; when it reaches zero, the alarm sounds and the page shows Time's up. Pause stops the clock and Reset takes it back to 10 seconds.
How long is 10 seconds in minutes?
10 seconds is 1/6 of a minute (0.17 minutes).
Can I use this for a New Year's Eve countdown?
Yes. Press Start at 11:59:50 PM by your device's clock and the alarm sounds at midnight. Phones and computers usually set their clocks from the network, but compare yours with a reliable clock if the exact second matters.
Will the alarm go off if I switch tabs?
In most desktop browsers, yes. The countdown is worked out from the real clock, and the alarm is scheduled with the browser's sound engine when you press Start, so it stays on time in a background tab. Phones can pause web pages when the screen locks, so keep the screen on — the timer asks the browser to do that where it can — and turn the volume up.
