Online Stopwatch
Content updated .
Start a stopwatch, record laps and keep a large time display in focus view.
How to use it
Press Start to begin, Pause to stop temporarily and Start again to continue. Lap records the total elapsed time at that moment. Reset clears the time and laps.
Useful example
For three practice rounds, record a lap after each round. Each entry is cumulative; subtract consecutive readings to find an individual round.
Tips
The display uses hours, minutes, seconds and hundredths. It uses the browser's monotonic clock rather than counting timer callbacks. Keep the tab open; it is not a certified sports timer.
Frequently asked questions
Are lap times individual or cumulative?
Each lap is the total elapsed time at that point. Subtract successive lap readings to calculate individual lap durations.
Does Reset remove laps?
Yes. Reset clears the clock and lap list. Pause stops timing without clearing either.
