Stopwatch & Timer

About the Stopwatch & Timer

The MyCalendarTools Stopwatch & Timer gives you two precise timing tools in one place. The stopwatch counts up from zero and is accurate to the centisecond (1/100th of a second), making it suitable for sports timing, study sessions, cooking, and any task where you need to measure elapsed time. The countdown timer counts down from a duration you set and alerts you with an audio beep and a screen notification when time is up.

How to use the Stopwatch

1. Click Start to begin counting up.
2. Click Pause to stop the clock without resetting it.
3. Click Start again to resume from where you left off.
4. Click Reset to return to 00:00.00.

How to use the Countdown Timer

1. Enter the number of minutes and seconds you want to count down from.
2. Click Start Timer — the display counts down in real time.
3. When it reaches zero, a short audio beep plays and a screen alert appears.
4. Click Reset to return to your original duration for another round.

Tip: Keep this browser tab open for reliable timer alerts. If you switch to another app, the timer still runs in the background but the audio alert depends on your browser's background audio permissions. For critical timing needs, consider keeping the tab visible.
