Four hours is half a shift, a long stretch of driving between stops, and the proving time most bread dough wants at room temperature. It is also the block anyone working to a deadline thinks in: a morning or an afternoon, not a day.
In a kitchen it is a slow braise. In a workshop it is how long a glue-up needs before the clamps come off. On a charger it is roughly a laptop from empty, which is why the number turns up in so many unrelated places.
The tip is to check in on a four hour job at the one hour mark rather than the two. Plans that go wrong mostly go wrong at the start, and an hour in you can still change the approach without losing the afternoon. At the halfway point the only realistic option left is usually to keep going.
Press start or the space bar. The end is stored as a clock time, so closing the laptop and opening it later does not lose a minute.
The time keeps passing and the page knows it: reopen and the countdown is correct, or already finished. A closed machine cannot play a sound, so use notifications if the moment matters.
Switch on desktop notifications and the browser will tell you wherever you are. Nothing is asked for until you turn that switch on, and it is off by default.
Tap the hours on the readout and type a bigger number, or use the eight, twelve and twenty four hour pages, which are set up for exactly that.
