Set a timer
Enter hours, minutes, and seconds, or choose a 1, 5, 10, or 25 minute preset. Start timer begins the countdown. The progress bar fills as time passes.
Pause holds the remaining time. Resume continues without counting the pause. Reset returns to your chosen duration so you can edit it or run it again.
For example, pause a five-minute timer after two minutes. It holds at three minutes until you resume. Pausing for ten minutes does not use up those remaining three minutes.
Background timing and notifications
The countdown compares your device’s current time with the finish time. It does not assume the browser updates exactly once per second. When you return to an open tab, the display catches up.
Browser notifications are optional and need permission. Your browser or device can delay them, especially during sleep or when a page is suspended. Keep a dedicated alarm for anything that must alert you reliably. This timer does not play a sound of its own.
If you want to count upward or record laps instead, use the Stopwatch.
