How to Use

  1. 1

    Choose the Timer tab for a fixed duration, or the To a date tab to count down to a specific date and time.

  2. 2
    Set your target

    Enter hours, minutes, and seconds — or tap a quick preset. In date mode, pick a future date and add an optional event name.

  3. 3
    Start the countdown

    Press Start to launch the live display. Use Pause to hold the timer and Resume to continue where you left off.

  4. 4
    Reach zero

    The display switches to a finished state and plays an optional sound. Press Reset or pick a preset to set up a new countdown.

Frequently Asked Questions

What is the difference between the two modes?
The Timer tab counts down a fixed duration you set in hours, minutes, and seconds. The To a date tab counts down to a specific calendar date and time. Days appear whenever 24 hours or more remain.
Does the countdown keep running if I switch tabs?
The countdown keeps running while the browser tab is open, including in the background. It stops if you close the tab — the timer is not saved between sessions.
Can I pause and resume the timer?
Yes. In Timer mode, Pause holds the countdown at its current value and Resume continues from exactly where it stopped. In To a date mode, Pause only freezes the display — Resume re-syncs to your chosen date, so the countdown still ends on time. Reset clears the countdown entirely.
Will it make a sound when time runs out?
If the sound toggle is on, a short chime plays the moment the countdown reaches zero and repeats every three seconds for up to 30 seconds, until you press Reset. You can turn the sound off at any time.
Which time zone does the date mode use?
By default the date and time you pick are read in your device time zone. To count down to a moment elsewhere — midnight in Tokyo, a launch in New York — open the Time zone picker under the date and search by city, region or UTC offset; the hint and the "Ends" line then show exactly which instant you are counting to. The choice is remembered on this device.
Is my countdown private?
Yes. The countdown runs entirely in your browser. Your durations, target dates, and event names are never sent to a server.
