3 Minute Timer

A hundred and eighty seconds

Three minutes is 180 seconds, and twenty runs make an hour. It is the shortest length that feels like a real block of time rather than a pause – long enough to do something, short enough that nobody wanders off.

Where three minutes turns up

• A round in professional boxing is three minutes, with a minute between rounds.
• The classic three-minute egg, soft in the middle.
• The sand timer in Boggle runs three minutes, which is why so many word games settle on that length.
• A pop song, near enough. Three minutes is the length radio built itself around.
• Three-minute talks, the format that forces one idea instead of five.

Running it in a series

Because three divides sixty, a three-minute block stacks cleanly: five rounds is a quarter of an hour, ten rounds is half of one. Add a one-minute gap between rounds, as boxing does, and each cycle is four minutes – so fifteen cycles is exactly an hour. The 1 minute timer handles the gap and the 4 minute timer covers the whole cycle if you would rather not switch pages.

One step down is the 2 minute timer, one step up the 5 minute timer. The full list is on the timer page.

Accuracy

The clock runs against your system clock, not against a counter that a sleeping tab can stall, so a backgrounded tab still lands on zero at the right moment. The sound is the weak part: a phone that puts itself to sleep may never play it. Do not lean on this for anything where missing the alarm matters – medication, an exam, a step in cooking that burns.
