Countdown Timer
Count down from any length of time and get an alarm at zero.
What is a countdown timer?
A countdown timer starts from a length of time and counts down to zero. This one counts down a duration, such as 25 minutes, rather than counting to a calendar date such as New Year. It suits tasks where the end point matters more than the time elapsed.
Common countdown durations
- 1 to 5 minutes: quick breaks, presentations, warm-ups
- 10 to 20 minutes: focused tasks, tidying, reading
- 25 to 30 minutes: study blocks and work sessions
- 45 to 60 minutes: lessons, meetings, longer sessions
Where countdown timers are useful
Teachers use them for activities, presenters to stay on time, and anyone who wants a clear finish line for a task. Press the Fullscreen button under the timer to show it large on a projector or second screen.
