Countdown Timer

Countdown timer with hours, minutes and seconds

What is it and how does it work?

A countdown timer lets you set a duration and counts down to zero, alerting you when time is up. Unlike a stopwatch that measures elapsed time, a timer tells you how much time you have left — making it the right tool when you need to finish something within a fixed window. Common uses span cooking, exercise intervals, meeting segments, study sessions and any time-boxed task.

This browser-based timer runs entirely client-side, so it works offline and does not require an account. It supports hours, minutes and seconds, plays an audible alert when the countdown finishes, and lets you pause, resume or reset at any point. Multiple presets (5 min, 10 min, 25 min Pomodoro) let you jump to common intervals with one click.

Common use cases

• Pomodoro technique: set 25 minutes of focused work followed by a 5-minute break timer to maintain concentration and avoid burnout.
• Cooking: time a pasta at 8 minutes while a sauce simmers for 20 — set two timers back-to-back.
• Presentations: use a 2-minute timer per speaker in a round-robin meeting to keep discussions on track.

Frequently asked questions

Will the timer alert me if I switch to another tab?

Yes. The alert is triggered by the browser even when the tab is in the background, as long as the page remains open. Depending on your OS and browser settings, an audio alert or notification will fire when the countdown reaches zero.

Does the timer keep running if I close the browser?

No. Browser-based timers stop when the tab is closed or the browser exits. For a timer that must survive browser restarts, use your OS clock app or a dedicated device.

What is a Pomodoro timer?

The Pomodoro Technique splits work into 25-minute focused intervals (Pomodoros) separated by 5-minute breaks. After four Pomodoros, take a longer 15–30 minute break. It's a popular productivity method for fighting distraction and mental fatigue.

Can I set a timer for more than 60 minutes?

Yes. Enter the hours field directly or add minutes beyond 60 — the timer converts them to hours and minutes automatically. There is no upper limit on the duration.
