Countdown Timer Online
This countdown timer starts at ten minutes and can be adjusted in settings. Use it for work sessions, classroom activities, exercise intervals, presentations, household tasks, or any ordinary event with a known end time.
Before you rely on the alarm
Keep the page open, check your device volume, and make sure the browser is allowed to play sound. Background-tab restrictions and power-saving settings can affect browser timers on some devices. Use dedicated equipment when timing is safety-critical or must remain accurate while the device sleeps.
If you need to measure elapsed time instead, use the online stopwatch.
