Timer
What Is This Tool?
Our online countdown timer lets you set any duration and count down to zero with an audio alert. Set hours, minutes, and seconds individually for precise control. The timer continues running even if you switch browser tabs. Use it for work sessions, cooking, fitness intervals, or any timed activity.
How to Use
- Enter the countdown duration using the hours, minutes, and seconds fields.
- Press Start to begin the countdown.
- Use Pause to temporarily stop and Resume to continue.
- Press Reset to return to the original set time.
- An alert plays when the countdown reaches zero.
Common Use Cases
- Timing work or study sessions with a fixed duration
- Cooking — counting down roasting, boiling, or baking times
- Fitness — timing exercise intervals or rest periods between sets
- Presentations — keeping track of time-limited talk slots
Tips & Tricks
- The timer keeps running if you switch tabs — check back when you hear the alert.
- Set the timer slightly longer than needed to account for setup or wind-down time.
- Use alongside the Pomodoro timer for a structured focus + break routine.
Frequently Asked Questions
Does the timer keep running if I switch to another browser tab?
Yes. The countdown continues accurately in the background even when the tab isn't active, and the audio alert still plays when it reaches zero.
Can I pause the countdown and resume it later?
Yes. Use the Pause button to stop the countdown at any point, then Resume to continue from exactly where you left off.
What happens when the timer reaches zero?
An audio alert plays to notify you. If your browser tab is muted or the sound doesn't play, check that your device's volume and browser tab audio permissions are enabled.
Can I set a very precise duration, like 90 seconds?
Yes. Set hours to 0, minutes to 1, and seconds to 30, or just enter 90 directly in the seconds field depending on how the input is structured — any combination of hours, minutes, and seconds is supported.
Does closing the browser tab cancel the timer?
Yes. Since the timer runs entirely in your browser with no server-side tracking, closing or refreshing the tab stops and resets the countdown.
