Online timer
Start a free online timer in seconds, or count down to a clock time in any time zone.
Timers
Measure elapsed time with a free stopwatch, pause controls, and split laps.
Elapsed time
Measure a task, a practice session, or a race. Record laps without stopping the overall clock. Each lap shows the split since the previous lap and the total elapsed time.
Worked example
Start the stopwatch, record a lap at 30 seconds, then another at 50 seconds. The second split is 20 seconds.
Elapsed time is derived from timestamps. Refresh restores the stopwatch in this tab; changes to your device clock may affect timing.
