Online Stopwatch

The online stopwatch counts time to the millisecond after you click the 'Start' button. You can add laps, and if you close the stopwatch, the value and laps will be saved automatically. For longer periods, the number of days passed will also be displayed.

You can set the accuracy for displaying fractions of a second in the stopwatch settings.

Use the 'Start' or 'Stop' buttons to control the stopwatch. Click the 'Lap' button to add a lap and the current time to the lap list. To reset the stopwatch and laps, click the 'Reset' button (this button appears when the stopwatch is stopped).

You can customize the stopwatch's appearance, including text color, type, and size, and these settings will be saved for your next browser session. You can add links to online stopwatches with various time values and lap lists to your browser's Favorites for quick access.
