2 hour timer

What a 2-hour timer is good for

How it works

Press Start and the 2-hour countdown begins; the bar and the browser tab show the time left. The timer counts to a fixed end time, so it stays accurate if you switch tabs, and an alarm sounds at zero while the numbers flash. Full screen makes the digits readable from across a room. Space starts and pauses, R resets. To share a different length, add ?t= and a number of seconds to the address: datetime.uk/timer/?t=9000 opens a 2 hour 30 minute timer.

For other lengths, use the online timer. To find out when your exams are, see exam dates.

Frequently asked questions

How long are A-level exams?

It varies by subject and board. With AQA, each of the three A-level Maths papers is 2 hours. Check your exam board's specification for other subjects.

Will the timer keep going if I switch tabs?

Yes. It counts to a fixed end time and the alarm is scheduled in advance, so it stays accurate in a background tab. Closing the tab or the browser stops it.

Can I set a timer longer than 2 hours?

Yes. Change the hours box before you press Start. The longest timer is 99 hours, 59 minutes and 59 seconds.
