About this 15 minutes timer
This is a straightforward 15 minutes countdown you can start in one click. It's built to run entirely in your browser, so there's no app to install and no account to create — just open the page and press Start whenever you need it.
People commonly use it for a snack or stretch break, letting dough rest, or a focused reading sprint. The countdown keeps accurate time even if you switch to another tab or your browser is minimized, and it plays an alarm sound the moment it reaches zero.
A quarter of an hour
Fifteen minutes is the standard short break in most workplaces and the length of a decent reading or revision sprint. In cooking it's the usual first check-in for baking, and the rest time most bread doughs want between folds. It's the shortest block that feels like real time rather than a snatched moment.

Tips for using a 15 minutes timer
- Fifteen minutes of focused reading a day adds up to roughly 15-20 books a year at average reading speed.
- Most dough recipes call for a 15-minute bench rest so the gluten relaxes before shaping.
- For studying, 15 minutes is long enough to get into a topic without the fatigue that kills recall.
Frequently asked questions
How do I set a 15 minutes timer?
Press Start above and this page counts down from 15 minutes automatically — no need to type anything in. If you want a different length, use the Add 1 Minute button while it's running, or pick another duration below.
Will the timer still work if I switch tabs?
Yes. The countdown is based on your computer's clock, not a simple on-screen tick, so it stays accurate even if this tab is in the background or your browser throttles it. The alarm still fires when time's up.
Does it make a sound when time is up?
Yes, if the sound toggle is checked (it is by default). The alarm plays right in your browser — no app or download needed. Some browsers require one click on the page first before audio is allowed to play.
