A dependable countdown for cooking, breaks, exams and meetings. The timer keeps accurate time in the background, and can play a soft tone when it finishes.
When to use it: kitchens, breaks, parking and any “time left” situation.
Frequently asked questions
Will the alarm sound if my device is muted?
The sound respects your browser’s audio settings. On some browsers an interaction with the page is required before audio can play.
Can I count down to a date days away?
This tool handles hours, minutes, seconds and a target time of day. For multi-day calendar spans, the Date Difference Calculator counts the days.
Can I run two timers at once?
Yes — open the tool in a second tab; each tab runs its own independent countdown.
What are good everyday uses?
Boiling eggs, parking meters, baking, study sprints and screen-time limits — set it and get a sound at zero.
Does the alarm repeat?
It signals when the countdown reaches zero; press Start again for a new round.
Will I see when it finishes?
The display reaches 00:00:00 and, if your browser allows audio, the optional sound plays.
