Time's up
Space to start or pause, R to reset, F for full screen.
An hour and a half: about one movie, one long exam or one soccer game. Press Start and the clock counts down from 1:30:00, then beeps at zero.
What people use a 90 minute timer for
- A movie night, since plenty of films run about 90 minutes.
- A practice exam or a long timed section, to build stamina for the real thing.
- A nap long enough for one full sleep cycle, which is often put at about 90 minutes.
- A soccer game of two 45-minute halves. Pause it for halftime.
How this timer works
- It remembers the moment it will end, so it stays right when you switch tabs or your phone locks.
- At zero it plays a few short beeps, vibrates on phones that can, and shows "Time's up" in the tab title.
- While it runs it asks the screen to stay on. Full screen makes the numbers big enough to read across a room.

Questions people ask
How long is a sleep cycle?
About 90 minutes is the figure people usually quote, but cycles vary from roughly 70 to 120 minutes and change through the night. Treat 90 as a rough guide for a nap, not a rule.
How long is a soccer game?
Ninety minutes of play in two 45-minute halves, plus stoppage time and a halftime break of about 15 minutes. Youth games are usually shorter.
Does the timer work without an internet connection?
Once the page has loaded, yes. The timer runs in your browser and does not need the network to count down or to beep.
