What is the 45 minute timer good for?
Forty-five minutes is the classic class period and a favorite deep-work block: long enough for real progress, with a natural stopping point before fatigue sets in. This free 45 minute timer marks the end with an alarm.
Pair it with a fifteen-minute break for the popular 45/15 study rhythm, or use it for meetings that need more room than a half hour allows.
Popular uses
- Deep work blocks (45/15 rhythm)
- Class-length study sessions
- Longer meetings

45 Minute Timer questions
How do I start the 45 minute timer?
Press the Start button and the countdown begins immediately. You can pause and resume at any point, or reset to start over.
Will the alarm sound if I switch tabs?
Yes. The timer is driven by your device clock rather than the animation, so it keeps accurate time in background tabs. Keep the page open and make sure your device volume is on to hear the alarm.
Can I pause and resume the timer?
Yes — the Start button becomes Pause while running, and Resume when paused. Reset returns the timer to its full duration.
Is this timer free to use?
Completely free, with no account or signup. It runs entirely in your browser.
