About This Tool
Set a countdown timer for any duration — minutes, hours, or a specific target date and time. Get audio and visual alerts when the countdown reaches zero. Useful for cooking, presentations, exams, workouts, and tracking time until events.
Frequently Asked Questions
- Can I set multiple timers?
- The tool supports one active countdown at a time. For multiple simultaneous timers (e.g., cooking multiple dishes), open the tool in separate browser tabs.
- Will the alarm work if my browser tab is in the background?
- Yes, the audio alarm will play even if the tab is not in focus. However, some browsers may throttle background tabs — keeping the tab visible ensures the most accurate display updates.
- What's the maximum countdown duration?
- You can set countdowns up to 99 hours, 59 minutes, and 59 seconds. For longer durations, use the date/time target mode to count down to a specific date.
- Does the countdown survive a page refresh?
- Refreshing the page resets the timer. For important countdowns, note the end time so you can restart if needed. The timer uses system time, so accuracy isn't affected by page load time.
