How to use the Timer & Stopwatch
Switch between Timer and Stopwatch.
For the timer, set the hours, minutes and seconds, then press Start.
Pause, resume or reset anytime; the stopwatch can also record laps.
Frequently asked questions
Yes. When the countdown reaches zero, a short beep plays and the display highlights. The sound uses your browser's audio, so make sure the tab is not muted.
The time is tracked from timestamps, so it stays accurate when you return to the tab. Background tabs may update the display less often, but the elapsed time is correct.
In stopwatch mode, Lap records the current time without stopping, so you can capture split times. Each lap is listed below the clock.
No. The timer and stopwatch run entirely in your browser and nothing is sent anywhere.
This tool combines a countdown timer and a stopwatch. The timer counts down from a time you set and sounds an alarm when it finishes; the stopwatch counts up and records laps.
Times are tracked from precise timestamps rather than a simple counter, so they stay accurate even if the tab is inactive for a while. Everything runs in your browser.
