45 Minute Timer
Press start and this timer counts down 45 minutes, then sounds an alarm.
A 45-minute timer is handy for a class-length study or work block, or a longer workout. That's 2,700 seconds.
How it works
This page is preset to 45 minutes — just press Start and it counts down to zero, then sounds an alarm even if you switch tabs (the tab title shows the time left). Pause and resume anytime, or Reset to start over. Space starts and pauses.
Need a different length? Try the 40-minute timer or 50-minute timer, or set any hours, minutes and seconds above. Counting down to a date instead? Make a countdown; to time how long something takes, use the stopwatch.
