45 Minute Timer

Forty-five minutes is a common length for school periods, lectures and tutoring sessions. This timer starts the moment the page opens and rings when the period is over.

It is also a good size for a longer study push: a full block of concentrated work followed by a proper break.

How to use this tool

1. Open the page; 45:00 starts counting down.
2. Press Pause (Space) if class is interrupted and press it again to continue.
3. Press Restart (R) to begin a fresh 45 minutes.
4. When the bell rings, press Stop or any key. +1 minute gives a little extra time.

For teachers and tutors

Show the timer on a projector or shared screen so students can see how much of the lesson remains. Plan the period in parts: a short starter, direct teaching, practice and a wrap-up, and glance at the countdown to stay on track.

Tutors can use it to keep a session to its booked length without checking a watch.

For students

Study for the full 45 minutes with one subject, then stand up and move for ten to fifteen minutes before the next block. Practice exams are easier to approximate if you give yourself the same time limit as the real paper: use this as the clock for a single section.

Other uses

Rehearsals for a presentation, a reading group slot, a soak in a bath, a long phone call you do not want to run over, or a batch task like sorting a folder of photos. Set the page up on a second screen and carry on.

Notes on accuracy

The page reads the device clock, so if the screen turns off, the time left will still be correct on return. Keep the sound unmuted if you rely on the end alarm.
