Using a browser stopwatch

The stopwatch is designed for everyday timing tasks such as cooking, short workouts, and study intervals.

Keep the page active

Browser timers may be delayed when a tab is in the background, a device is asleep, or power-saving features are active. For official race timing, laboratory measurements, or other precision work, use dedicated timing equipment.

Record your own laps

If you are timing repeated intervals, write down each split as you go and use the same start and stop rule each time. Consistent procedure matters more than extra decimal places for casual comparisons.

Tool notes are based on the current implementation and are provided for general information. Review important outputs before relying on them.
