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?

Frequently asked questions
How do I set a timer for 40 minutes?
This page is already set to 40 minutes. 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 40 minutes.
How many seconds are in 40 minutes?
2,400 seconds, or two-thirds of an hour.
How long is a rugby match?
A rugby union match is 80 minutes of play: two 40-minute halves with a halftime break of up to 15 minutes. Stoppages for injuries and reviews add to the real time.
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.
