Online Timer

How to use this timer

Set duration: enter hours, minutes and seconds, or tap a preset button.
Start: the timer counts down in real time. You'll see hours, minutes and seconds remaining.
Alarm: when the timer reaches zero, a sound plays and the display flashes so you notice even if you switched tabs.
Reset: stops and clears the countdown so you can set a new duration.

When to use a timer

Cooking and baking

Set exact minutes for boiling eggs, resting dough, marinating meat, or oven stages. The alarm ensures you never overcook.

Pomodoro technique

Focus for 25 minutes, then take a 5-minute break. Our 25-minute preset is built for this. Pomodoro is one of the most effective time management techniques for students and remote workers.

Workouts and intervals

Tabata, circuit training, stretching or rest periods. If you need to measure elapsed time instead of a countdown, use the stopwatch.

Meetings and presentations

Keep sections on track, time lightning talks, or enforce short standups.

Frequently asked questions

Does the alarm play with the tab in the background?

Yes, the sound plays as long as your browser allows audio playback. Modern browsers sometimes throttle background tabs; keeping the tab visible guarantees perfect timing.

What happens if I close the tab?

The timer stops. It runs entirely in your browser and doesn't save state. Leave the tab open for the duration you set.

Can I run multiple timers at once?

Open the timer page in multiple tabs — each runs independently.

Is it free and private?

Yes. No signup, no tracking of your timer usage. Everything runs locally in your browser.

Timer vs stopwatch vs countdown — what's the difference?

A timer counts down from a duration you set (e.g. 25 minutes). A stopwatch counts up from zero. A countdown counts down to a specific future date and time.
