Countdown Timer
Set hours, minutes and seconds and count down to zero.
A timer for anything
Set a duration in hours, minutes and seconds and press start. The timer counts down live and announces Time's up! when it reaches zero. Use it for cooking, workouts, focused study bursts, presentations or any short task that needs a firm limit.
Start, pause and reset
Pause to hold the clock and resume exactly where you left off, or reset to return to your chosen duration. Everything runs in your browser with a single self-cleaning timer, so nothing is left ticking in the background once you pause, reset or finish.
How to use the Countdown Timer
- Set the duration. Enter hours, minutes and seconds for your countdown.
- Press start. Watch the clock count down in real time.
- Pause or resume. Pause to hold, then start again to continue where you stopped.
- Reset when done. Reset returns the clock to your chosen duration.
Frequently asked questions
What happens when the timer reaches zero?
The clock stops at 00:00:00 and the status changes to "Time's up!". The interval is cleared automatically so nothing keeps running.
Can I pause and resume?
Yes. Pause holds the remaining time, and pressing start again continues the countdown from that point.
Will it keep counting in a background tab?
Browsers may throttle timers in hidden tabs, so keep the tab visible for the most accurate countdown.
Is a sound played?
The timer shows a clear "Time's up!" message on screen. Keep the tab visible so you notice when it finishes.
