What a minute is for

A minute is the shortest span most people can hold something without wanting to know how much is left. Below it you can count in your head; above it you stop being able to. That is why so many held exercises, quick drills and short rests are exactly one minute long — it is the point where a timer starts earning its place.

It is also the length people are worst at estimating. Asked to judge a minute without a clock, most adults stop somewhere between forty and eighty seconds, and the error runs in a predictable direction: when you are working hard the minute feels longer, so you stop early, which is precisely the case where the full minute was the point.

For anything you are counting rather than holding — reps, breaths, pulses — the timer is doing the easier half of the job. It frees you to count the thing itself, which is the half that cannot be automated.

What people use it for

  • Planks, wall sits and other held positions
  • Rest between sets
  • Counting a pulse or a respiratory rate
  • A one-minute drill, spelling test or mental maths round
  • Brushing timing for one half of the mouth

How it works

The end of the countdown is fixed the moment you press start, and the alarm is scheduled then too. On a timer this short that is what keeps it honest: a delay of even a second is a noticeable fraction of the whole thing.

Both fields are editable, so this becomes a ninety second or a forty-five second timer without leaving the page.

Space starts and pauses, R resets. Neither needs the mouse, which matters when your hands are busy with whatever you are timing.

Questions

How do I start a one minute timer?

Press Start, or press Space. It is already set to sixty seconds, so nothing needs configuring first.

Will the alarm be exactly on the minute?

Yes. The finishing moment and the alarm are both fixed when you press start, rather than being triggered by a countdown that has to run first.

Can I make it 90 seconds instead?

Set minutes to 1 and seconds to 30. Any combination up to a day works.

Why is a minute so hard to judge?

Time perception stretches with effort and attention. Under exertion a minute reliably feels longer than it is, which is why people cut held exercises short and why a timer beats counting.

Does it work if I put my phone down?

Yes. The screen is held awake while it runs, and even if the screen goes off the finish time does not move, because it is read from the clock.

Can I use it for a plank?

That is one of the commonest uses. Start it, then look away — watching the digits is the fastest way to make a minute feel like three.

Is there a link I can bookmark?

This page is the bookmark. Any other length can be linked directly by adding the minutes to the address, such as /timer?m=3.
