How to use the countdown
Set a target date — or a duration like 10 minutes — and watch days, hours, minutes, and seconds tick down. Fullscreen mode is meant for a shared display.
Pick a target
Use a date and time, or switch to duration mode for a simple countdown from now.

About this tool
Countdowns work for exam start times, product launches, New Year, and “five minutes left” on a workshop. For repeating work/break cycles, use the pomodoro timer instead.
Frequently asked questions
- Does it keep running if I switch tabs?
- Yes. The remaining time is computed from the clock, not from a timer that pauses in background tabs.
