How do I set the countdown timer?

Use the + and - buttons next to hours, minutes, and seconds to set your desired duration. You can also click directly on the number field and type a value. Once set, click Start to begin the countdown.

Does the countdown timer make a sound when finished?

Yes, the timer plays an audio beep when the countdown reaches zero. This uses your browser's Web Audio API, so no external audio files are needed. Make sure your device volume is not muted.

Can I pause and resume the countdown?

Yes, click the Pause button to pause the countdown and click Start again to resume from where you left off. The timer remembers your position even if you navigate away (within the same tab).

Does the countdown timer work in the background?

The timer continues to count down as long as the browser tab is open, even if you switch to another tab. However, some browsers throttle background timers, so there may be slight drift. The timer will still alert you when done.

Is there a maximum time I can set?

The maximum duration is 99 hours, 59 minutes, and 59 seconds — that's almost 4 full days. For most practical purposes (cooking, workouts, meetings, study sessions), this is more than enough.
