45 Minute Timer

A free 45 minute countdown timer that runs in your browser. Press play and the progress ring slowly closes over 45 minutes; a chime and a pulse mark the end. Pop it out into a small always-on-top window to keep the time in sight while you work.

Why 45 minutes works

Forty-five minutes is the length of a school lesson for a reason: it's about as long as most people can hold genuinely focused attention before quality drops. It also fixes the main complaint about short Pomodoro intervals — that 25 minutes ends just as you're getting warmed up. Demanding work like programming, writing or mathematics often needs ten or fifteen minutes just to load the problem into your head; a 45 minute block leaves real time to use that momentum.

The 45/15 rhythm

A popular pattern is 45 minutes of focus followed by a 15 minute break — a clean hour per cycle, four cycles in a half-day. The longer break is earned: walk somewhere, eat something, actually rest. If 45 still feels short for your work, try a 60 minute timer or a full 90 minute deep-work block.

Frequently asked questions

Is 45 minutes better than 25 minutes?

It depends on the task. Choose 45 for deep, single-threaded work where context-loading is expensive; choose 25 for lighter tasks, low-energy days, or when starting at all is the hard part.

How long should I rest after a 45 minute session?

Ten to fifteen minutes. Shorter than that and the fatigue carries into the next block; much longer and re-starting gets hard. Switch this timer to Break mode and use +5 to set the length you want.
