What a 45 minute timer is for

Forty-five minutes is a school period, a gym session and about the longest most people can hold real concentration before quality starts to fall away.

What people set it for

How this timer behaves

The countdown is stored as the moment it should finish, not as a number being decremented, so switching tabs or minimising the window cannot make it run late, and pausing and resuming is exact. Through the final minute the readout and its ring turn red and pulse, giving you a warning before the alert rather than only at it.

It does not start on its own. The alarm is generated in your browser, and browsers keep audio silent until you interact with the page — so a timer that started by itself would be a timer that finished in silence. One tap on start is what makes the sound work.

Frequently asked questions

Is forty-five minutes better than twenty-five for focus?

It depends on the work. Twenty-five suits tasks you are avoiding, because starting is easy. Forty-five suits work with a long warm-up — code, writing, analysis — where a twenty-five minute break arrives just as you have got going.

Can I see the time left without looking closely?

The ring around the readout empties as the countdown runs, so the proportion left is readable at a glance from across a room.

Will the tab survive that long in the background?

The timing will. The countdown works from a target moment, so however aggressively the browser throttles the tab, it finishes at the right time.
