Countdown timer
Set a countdown for work, cooking or a break, with pause, resume and an optional alarm.
Ready when you are.
Keep this tab open. Closing or refreshing it clears the timer. Reset to change a running or paused timer.
How it works
Enter hours, minutes and seconds, or choose a preset, then press Start. Pause and resume whenever you need to; Reset stops the countdown and lets you change its duration.
The timer uses an end time rather than counting interval ticks, so it catches up correctly when you return from another tab. The remaining time also appears in the browser tab title.
Enable the sound option for a short alarm when time runs out. Keep the tab open: closing or reloading it clears the timer. Muted audio, device sleep and browser background restrictions can delay or prevent the alarm, so do not rely on it for critical reminders.
