Five minutes is the everyday unit: press start and this preset timer runs 300 seconds, then signals with sound and a visible alert. It covers a medium boiled egg, a break that does not quietly become twenty minutes, or one small task you keep pushing away. Change the fields for a different length.

How long does an egg need at five minutes?

In boiling water a medium egg straight from the fridge is soft with a runny yolk after about five minutes, waxy at seven and hard at about ten. One thing changes the whole scale: altitude. Water boils at 100 degrees at sea level but only at around 96.7 degrees at 1,000 metres, because the air pressure is lower — so the same egg needs noticeably longer in the mountains.

Why set a timer for a five minute break?

Because an untimed break has no end. Five minutes without a timer turns into a scroll session, and the return to the task costs more than the break saved. With a fixed end you can spend the five minutes properly — standing up, looking out of the window, getting water — instead of half-watching the clock the whole time.

Does it still ring if I close the laptop?

No, and no browser timer does. A closed lid suspends the page, so nothing can play. What does work is the case people actually hit: another tab, another window, a phone screen that dims. The remaining time is recomputed from the start timestamp whenever the page becomes visible again, so it never drifts.

How to set the timer

  1. Press start; five minutes are already set.
  2. Leave the tab open in the background — the title shows the remaining time.
  3. At zero you get a tone and a visible alert; reset to run the five minutes again.

Frequently asked questions

Is five minutes right for a soft boiled egg?

For a medium egg from the fridge in boiling water, yes — the white is set and the yolk still runs. Larger eggs need roughly half a minute more, eggs at room temperature slightly less, and at altitude everything takes longer because water boils below 100 degrees.

Can I pause the timer and continue later?

Yes. Pause freezes the measured time, and start continues from exactly there. The time you spent paused is never counted, because the calculation only ever adds the spans that actually ran.

Does the timer keep running when I switch tabs?

Yes. The remaining time is calculated from the timestamp at which you pressed start, not by counting ticks. Browsers slow background timers down to about one call per minute, and a sleeping device stops them completely — a counting timer would fall behind by exactly that amount. This one simply subtracts again when the tab comes back and shows the correct value.

Does the timer send anything to a server?

No. No server is involved at all: the countdown is a subtraction against your device clock, done entirely in JavaScript in your browser. There is no account, no cookie for the timer, and nothing is uploaded or sent anywhere. You can load the page, switch to airplane mode and the timer still runs — which is the simplest way to verify the claim yourself.
