15 minute timer

A quarter of an hour, ready to run

Open the page and this 15 minute timer is already set to 15:00. Press the space bar or click "Start" to begin. You will hear the beeps when the quarter-hour is up.

What can you do in fifteen minutes?

• Half-time. In football the interval between the two halves must not exceed 15 minutes.
• A long Pomodoro break. After four 25-minute work sessions, the method calls for a longer rest of 15 to 30 minutes.
• A quarter of American football. Each quarter has 15 minutes on the game clock, even if it takes far longer to play.
• A short HIIT session. Thirty seconds of effort, thirty of rest, fifteen times over.
• White rice. Depending on the variety it takes roughly 10 to 18 minutes. Follow the packet.
• A stand-up meeting. Fifteen minutes is the usual cap for a daily team catch-up.

Tips for classrooms and meetings

Put the timer on the projector in "Full screen": the digits can be read from the back row and the progress bar shows at a glance how much of the quarter-hour has gone. For silent reading or an exam-style exercise, untick "Sound at the end" so the finish is marked by flashing digits and nothing else.

Frequently asked questions

What happens when I pause?

The time freezes to the second and the button changes to "Resume". Deal with the interruption, click again, and the countdown continues from where it stopped.

Can I see the time left without keeping the page in view?

Yes. The remaining time is shown in the title of the browser tab and keeps updating while you work in another tab.
