About this online timer
This free online timer counts down from any number of minutes and seconds you enter. Press Start to begin the countdown, Pause to freeze it, and Resume to continue from where you left off. When the timer reaches zero, the display flashes red and a "Time's up!" message appears. The blue progress bar gives you a visual sense of how much time remains at a glance. Unlike a stopwatch, this tool counts down — perfect for knowing exactly when something is done.
How to use the timer
Enter the number of minutes and seconds you need, then press Start. You can also press Enter in either input field to start immediately. Press Pause to stop the countdown without resetting it, and Resume to pick up again. Press Reset at any time to return to the values in the input fields. You can change the time while the timer is paused by pressing Reset and entering a new value.
Common uses for an online timer
An online timer is useful anywhere a fixed time window is needed: boiling eggs, resting dough, timed writing exercises, classroom activities, sprint intervals during a workout, or any task where you want to know the moment time is up without watching a clock. Having the countdown visible in a browser tab means it's always in view alongside your other work.
Runs entirely in your browser
This timer uses JavaScript's setInterval to tick every second. No data is sent to any server — your timer settings remain on your device only. The timer works correctly even if you switch tabs, because remaining time is tracked in memory, not by counting individual ticks. For precision tasks, note that browser tabs may throttle background timers; keep the tab visible for best accuracy.
