Online Stopwatch
This online stopwatch measures elapsed time rather than counting down to an alarm. Start, pause, resume, record laps, and reset from the browser. It can be used for practice rounds, workouts, demonstrations, experiments, or everyday timing.
How it differs from a countdown
Choose a stopwatch when you do not know the finishing time in advance. Choose a countdown when you want an alarm after a fixed interval. Browser timing is suitable for ordinary use but should not replace certified equipment for competition, laboratory, medical, or safety-critical measurement.
For a fixed end time, open the countdown timer.
