15 Minute Timer
Fifteen minutes is a quarter hour: a Pomodoro long break, a coffee break or a solid short workout. Press Start and it rings at zero, even if you switch tabs.

Sound needs one tap on the page first (a browser rule). Keep this tab open: closing it stops every timer’s alarm. Why timers stay accurate in background tabs.

Questions
How do I set a 15 minutes timer?
Press Start on this page. The 15 minutes countdown begins at once and rings when it reaches zero. You can also press the space bar to start and pause.
How many seconds are in 15 minutes?
15 minutes is 900 seconds.
Will it still ring if I switch to another tab?
Yes, while the tab stays open. The alarm is scheduled for an exact end time when you press Start, so a background tab does not delay it. Turn on notifications to get a system alert too.
Can I run this alongside other timers?
This page runs one big timer. For several at once, open the main countdown timer board, which runs any number of labelled timers side by side.
