One minute is a plank, a one-sentence pitch, or the pause while you decide whether a notification deserves an answer. Set it before you start the hold. Looking for the button eats the minute.
In a classroom, one minute is a transition cue: chairs in, pencils down, eyes up when it rings. Press space to start or pause, R to reset, and F for fullscreen. The screen can stay awake after you start, using the wake lock your browser allows. Pick the alarm before you begin. A bell, a chime, a beep, or a short digital pulse all come from the Web Audio API, so there is no sound file to wait on.
This page is the 1 minute countdown and nothing else is running underneath it. Related lengths are linked under the guide if you want a neighbor, and the timer itself stays above the fold.

What is 1 minute actually good for?

Will the countdown drift if I switch tabs?
No. The end is a timestamp. The display is the gap between that timestamp and now, so a background tab does not lose seconds the way a ticking counter would.
