Why 12 minutes works for a study block

Twelve minutes is long enough to finish a real task and short enough to start without dread. It fits neatly inside a revision session. You can read one section of a textbook, answer a page of practice questions, or review a set of notes before a break. The timer counts down from the current time on your device, not by counting ticks. That means it keeps honest time even if you switch tabs or your screen sleeps. The display refreshes several times a second, so the seconds you see are real seconds.

Common things people time at 12 minutes include a reading sprint, one exam section, a short presentation slot, and a rest between longer work blocks. A reading sprint at this length covers a few pages without fatigue. An exam section often runs 10 to 15 minutes, so 12 minutes is a safe practice target. A presentation or lightning talk can fit inside 12 minutes with time to spare. A rest between sets is usually 60 to 90 seconds, so 12 minutes is better for a full round of several sets.

Frequently asked questions

How do I set a timer for 12 minutes?

Open the timer page and type 12:00 in the duration field. Press Space or the start button. The countdown begins from the current time on your device. You can switch tabs or let the screen sleep, and the timer will still end at the right moment.

Does the 12 minute timer keep running if I close the tab?

No. A running timer survives a page reload on the same page, but closing the tab ends it. The end time is stored in the browser for that tab only. Keep the tab open in the background if you need the alarm to sound.

Can I change the 12 minute timer to a different length?

Yes. Type a new duration such as 8:00 for eight minutes, 45m for forty-five minutes, or 1h 30m for ninety minutes. You can also enter a clock time like 14:30 to count down to that moment instead of a fixed length.
