45 minute timer
Focus25:00
Forty-five minutes is the length of a typical class period in many schools, and a solid block for studying, teaching or training. The countdown on this page is already set to 45 minutes and starts with one click or the Space bar. When it ends, your alarm rings and it is time for a real break.
Borrow the class-period rhythm for studying
Many schools build their day around lessons of roughly 45 minutes, and the rhythm is worth borrowing at home: it is long enough to cover a topic properly and short enough to keep your attention reasonably fresh. For exam review, give each 45-minute block to one subject or one chapter, then switch or rest.
A popular way to structure a study day is the 45/15 rhythm: 45 minutes of work followed by a 15-minute break. A longer break is easier to respect than a short one, and it leaves time to eat, walk or get some air. Here, simply start a new countdown after each break; if you prefer breaks that start automatically, use the Pomodoro timer on the home page.
Lessons, tutoring and deep reading
The same length works well when you are the one teaching, or when you need uninterrupted time with a difficult text.
- Private lessons and tutoring: keep the timer in fullscreen or in the floating window so you both know how much time is left.
- Online classes and music lessons with a clear start and end.
- Deep reading: a long article, a contract or a textbook chapter, with a quiet forest or rain sound in the background.
- A gym session: a warm-up, your main lifts and a few accessory exercises fit in 45 minutes.
- Writing sessions for an essay or a thesis chapter.

Frequently asked questions
How do I set a 45 minute timer?
Press Start or the Space bar, since the countdown is already set to 45 minutes. If you change the duration, the 45 min chip brings you back in one click.
Is 45 minutes a good study session length?
For many students it is a comfortable length: long enough to go into a topic in depth, short enough to stay attentive. If you struggle to focus that long, start with 25 or 30 minutes and build up.
What is the 45/15 study method?
It alternates 45 minutes of focused study with a 15-minute break. You can run it here by starting a new 45-minute countdown after each break, or use the Pomodoro timer on the home page if you want breaks to start on their own.
Will I know when the 45 minutes are over if I am in another app?
Yes. The alarm rings at the end, you can turn on desktop notifications, and the floating mini timer shows the countdown on top of your other windows.
