15 Minute Timer Online
Fifteen minutes is the classic "just start" block — short enough to beat procrastination, long enough to make a dent. Use it for a study sprint, a 15-minute tidy of one room, a short HIIT session, or a proper break. The alarm sounds when time is up.

About the 15 minute timer
Fifteen minutes is the classic Pomodoro long break — the rest after four 25-minute focus blocks. It is also one full circuit of a beginner yoga sequence, the length of most pizza-oven cycles, and exactly the gap that fits between meetings on a packed calendar. Fifteen minutes is too long for a 'quick break' and too short for a 'real task', which makes it the perfect interval for genuine recovery — when you stop, stretch and reset before going back to work.
When a 15 minutes timer is the right tool
- The long Pomodoro break — perfect after four 25-minute focus blocks.
- A yoga or mobility flow that hits every major joint in sequence.
- A walking break to clear your head between back-to-back meetings.
- Most pizza ovens cook a single pizza in 12-15 minutes — set the timer when it goes in.
- Quick decluttering of one shelf or one drawer.
- Reading a single chapter of a typical novel.
- A focused journaling block at the start or end of the day.
- Cool-down walk after a HIIT or running session.
How to use the 15 minute timer
- Use it as your Pomodoro long break — press Start after four focus blocks and step away.
- For a yoga or mobility flow, start it and let the timer keep the pace so you stop clock-watching.
- It keeps counting accurately even when another tab is open.
- At zero the screen flashes and the alarm plays four times, so you notice from across the room.
- Press Reset (R) to repeat, or bookmark /15-minute-timer for instant access.
Tips for getting the most out of a 15 minutes timer
- Pomodoro's fifteen-minute break is the most-skipped rule. Skip it once a week, not every day — the breaks are what make the technique sustainable.
- Fifteen minutes of yoga every day beats forty-five minutes once a week, on every flexibility marker that has been studied.
- If you have fifteen minutes before a meeting, do nothing — read, walk, look out the window. Cramming one more email in is what makes you tired by 4pm.
- Set the timer when reading non-fiction; fifteen minutes is enough for one solid chapter without losing the thread.
15 Minute Timer FAQ
Why is fifteen minutes the Pomodoro long break?
Cirillo tested longer and shorter values and landed on 15-30 minutes after four focus blocks. It matches the brain's appetite for rest after roughly two hours of cycled focus — enough to recover, short enough to keep the day moving.
Is fifteen minutes enough yoga to matter?
Yes — daily fifteen-minute yoga sessions outperform weekly forty-five-minute classes on flexibility and self-reported stress in nearly every comparison study.
Will the 15 minutes timer ring if I close the tab?
No — the alarm only fires while the tab is open. Keep the tab open or install ClockAura as a Progressive Web App from your browser to leave it running in the background between sessions.
Can I use the keyboard?
Press Spacebar to start or pause and R to reset. Shortcuts work whenever the page is focused and you are not typing into an input field.
