What Is a Stopwatch?

A stopwatch is a timekeeping tool designed to measure the amount of time that passes between a starting point and a stopping point. Unlike a clock that displays the current time of day, a stopwatch measures the duration of an activity. Lap timing lets you record intermediate intervals without resetting the overall timer.

Common Uses of a Stopwatch

You can use an online stopwatch to time workouts, running sessions, study periods, practice tests, presentations, cooking tasks, games, and other everyday activities. Teachers and students can use it for classroom exercises, while athletes can record lap intervals during training.

Yes. Press the Lap button while the timer is running to record both the current lap duration and the total elapsed time.

Does the stopwatch need an internet connection?

How accurate is this stopwatch?

The tool uses the browser's high-resolution performance clock to calculate elapsed time. Display updates can be delayed by browser scheduling, background tabs, or device performance, so it is not a substitute for certified precision timing equipment.
