13 Minute Timer – Free Visual Countdown Timer with Alarm

Press Start to run this 13 minute timer from 13:00. The shrinking circle and large digits show the time left, with a chime at the end.

For a classroom writing activity, allow 1 minute to read a prompt, 10 minutes to write and 2 minutes to review. Tell the class when to switch stages: this is a single countdown, not an automatic interval timer.

Use F for full screen on a projector and Space to pause for a question. R resets the countdown to 13 minutes. To use another length, choose a time above or enter it in Custom time.

How to use the timer

Tap a time (or type your own, like 7, 2:30 or 1h 15m) and press Start.
Use Full screen on a supported browser to show the timer on a projector, smartboard or TV. Check the actual display before relying on it.
When the time is up, the timer shows Time’s up! and attempts to play a chime if sound is on. Keep the device awake and test the audio first. Reset prepares another round.

Frequently asked questions

How do I display a 13 minute timer for a class?

Open this page on the computer connected to your projector or display. Press Start, then F for full screen. Test the device volume before class if you want the end chime.

Does it ring at each stage of the writing activity?

No. The suggested 1 + 10 + 2 minute activity uses one 13-minute countdown. The chime plays only at the end; the teacher gives the stage instructions.

Will the timer keep running if I switch tabs?

The timer calculates the remaining time from an end time and can catch up after a delayed update. Browsers can throttle or suspend hidden pages, so an alarm may be delayed. Keep the timer visible and the device awake when timing matters; sleeping devices and closed tabs are not supported.
