What a 23 minute timer is good for

Twenty-three minutes is close to a classic Pomodoro without being one. People who find 25 minutes slightly too long for their focus often settle on twenty-three, and it is also a useful cap for a task that tends to drag on.

A study block

Twenty-three minutes of focus followed by a five minute break gives a rhythm just short of the classic Pomodoro.

Capping a task

Give a task you keep putting off exactly twenty-three minutes. A fixed end makes it much easier to start.

A bath

A warm bath of twenty minutes or so is often suggested before bed. Twenty-three gives time to get in and settle.

Brown rice in a pressure cooker

Brown rice cooks in about twenty-three minutes on high pressure in many electric pressure cookers, including release time.

To pace yourself, glance at the disc rather than the numbers. With the 23 minute timer running, half the colour has gone after 11 minutes 30 seconds, and when only a quarter is left you have 5 minutes 45 seconds to wrap up. Open fullscreen if the timer needs to be read across a room, and add a label so everyone knows what the 23 minutes are for.

How to use the 23 minute timer

  1. It is ready

    The dial is already set to 23 minutes. To change it, drag the disc, tap a preset or open Custom.

  2. Press Start

    Or press the Space bar. The red disc shrinks back towards 12 o’clock as the time runs down.

  3. Watch the disc

    Read the time left at a glance, or open fullscreen for a big dial that fills the screen.

  4. Time’s up

    Your alarm plays until you press Stop. Press Reset or R to run the same time again.

Why use this timer

Why a visual timer helps

A shrinking disc turns time into something you can see. You read how much is left at a glance, without doing sums on a clock, and an invisible deadline feels less stressful when you can watch it approach. That is why visual timers are a staple in classrooms and are widely used by people with ADHD and autistic children and adults. Read our guide to using a visual timer, how it helps with ADHD time blindness, classroom transitions and autism.

Why this timer is accurate

The countdown is anchored to your device clock rather than counted in animation frames. It does not drift if you switch tabs or your screen sleeps: it keeps running in the background and still sounds the alarm on time. When you come back, the disc jumps straight to the correct position.

Frequently asked questions

There are 1,380 seconds in 23 minutes. That is 0.3833 of an hour, or one thousand three hundred and eighty seconds written out.

A focus block slightly shorter than a Pomodoro, capping a task that always drags on, a relaxing bath before bed, or cooking brown rice in a pressure cooker.

Yes. The 23 minute countdown is anchored to your device clock rather than counted frame by frame, so it stays accurate in a background tab and the alarm still fires when the 23 minutes are up.

No. The 23 minute timer runs in your browser on phone, tablet and desktop. It is free, and there is no account, app or download.

Yes. Press the fullscreen button or the F key. The dial fills the screen, so the remaining part of the 23 minutes is readable from the back of the room.

Yes, once this page has loaded. Nothing is sent over the network while the 23 minutes count down, so a dropped connection will not stop the timer.

It depends on your attention span. If you keep losing focus in the last few minutes of a 25 minute block, try twenty-three. The method matters more than the exact number.

When the 23 minutes are up the disc is empty, the screen shows Time’s up! and your alarm plays until you press Stop. It stops by itself after five minutes.
