20 Minute Timer
Twenty minutes is the bargain you strike with yourself. Almost nothing is unbearable for twenty minutes, which is why it is the number people use to start the things they have been circling for a week.
What a 20 minute timer is good for
The nap is the best-known use. Twenty minutes is about the longest you can sleep and still come out the other side clear-headed rather than drugged, which is why it turns up in every piece of advice about napping at work. A few minutes to fall asleep and a short stretch of light sleep is the whole recipe.
It is also a natural workout unit. A circuit of stations run for twenty minutes, an interval session, or the amount of cardio a person will agree to on a day they did not want to go. Cooks use it for the roasting stage that needs checking rather than the one that needs watching.
The other half of its life is procrastination management. Twenty minutes of the tax return, twenty minutes of the essay, twenty minutes of the cupboard nobody has opened since spring. People with ADHD often describe the same trick, sometimes alongside a body-doubling call where someone else works in silence on the other end.
How to use this timer
The countdown above is already set to 20 minutes. Press play to start it, or use the boxes to change the length if you want something else. The alarm keeps ringing until you stop it, so it still reaches you from another tab or another room.
Reset returns the clock to 20 minutes rather than to zero, which is what you want when you are running the same block more than once.
The twenty minute rule for starting things you are avoiding
Avoidance is rarely about the work. It is about the size of the work, which is unknown and therefore assumed to be enormous. A job with no visible end is one your brain will keep postponing in favour of something with edges.
Twenty minutes gives it edges. The deal is explicit: you work for twenty minutes and then you are allowed to stop, with no obligation and no guilt. That is a small enough price that the arguing stops and the starting happens.
What usually follows is that you do not stop. Beginning is the expensive part, and once the file is open and the first paragraph is moving, continuing costs almost nothing. But the deal has to be genuine. If twenty minutes is secretly a trick to get you to work for two hours, you will know, and it will stop working by next week.
Frequently asked questions
Why do people say twenty minutes is the ideal nap?
It is the point that balances benefit against grogginess. Sleep deepens after roughly twenty minutes, and waking from those deeper stages produces sleep inertia, the heavy feeling that can last half an hour. Twenty minutes is usually enough to restore alertness while staying clear of it.
Can I use a twenty minute timer instead of a pomodoro?
Certainly. Twenty-five is conventional, not compulsory, and plenty of people find twenty fits their attention better, especially early in the day or on work they find difficult. The structure matters more than the number: a fixed block, then a real break.
Can I set it to repeat automatically?
Not from this page, which runs a single countdown. The pomodoro timer on the homepage does repeat automatically, and you can set its work interval to twenty minutes so it cycles through blocks and breaks without you touching it.
Is there a full screen mode?
Yes, the expand control in the menu takes the timer fullscreen, which is useful for a class, a gym or a shared screen where people need to read the remaining time from a distance. The keyboard and the on-screen controls both keep working while it is fullscreen.
