How to use this online timer

Pick a preset close to your target, adjust the remaining minutes or seconds, then decide whether you want sound, notifications, or fullscreen before you start. The page works well for study blocks, workouts, cooking, drills, and short meeting segments where one visible countdown should stay authoritative.

Quick setup

  1. Enter hours, minutes, and seconds or choose a preset such as 5, 25, or 60 minutes.
  2. Test sound, notifications, and fullscreen on the device you will actually use.
  3. Start the countdown and use +1 min, -10 s, or keyboard shortcuts if you need small live adjustments.

Helpful note

The share link keeps duration and display settings, but it does not keep the running or paused state. If you need several countdowns at once, use the multi timer from the related tools section.

FAQ

Will the timer drift in the background?

Display updates can throttle in background tabs, but the remaining time is calculated from Date.now() so it stays accurate.

Does the share URL include the running state?

No. Only settings are shared. Start/pause state is not included.

Will the alarm always play if my tab is muted?

No. Browser and OS audio policies can block playback. Test sound on the target device before relying on alerts.

Can I pause and resume without losing accuracy?

Yes. The timer stores timing checkpoints and recomputes remaining time, so pause/resume is stable for normal use.

Can I prefill countdown values by URL?

Yes. Settings links can prefill timer configuration, which is useful for repeated sessions or shared workflows.
