1 Hour Timer FAQs
Can I use the 1-hour timer for exam practice?
Yes. Many exam sections are 60 minutes: start the timer as you begin and stop writing when it rings. For longer papers use the 2-hour or 3-hour timer.
How do I use the 1 hour timer?
Press Start and the timer counts down from 1 hour. You can pause and resume at any time, or press Reset to start over. When the countdown reaches zero you’ll see “Time’s up!” and, if sound is on, hear an alarm.
How long is 1 hour?
1 hour is 60 minutes or 3,600 seconds.
Will the timer keep running if I switch tabs?
Yes. The countdown is based on your device clock, so the remaining time stays accurate in a background tab and the tab title shows the time left. Browsers may delay sounds in background tabs and cannot play them if the tab is closed or the device is asleep, so keep the page open for important alerts.
Why didn’t I hear the alarm?
Check that the sound button is on and your device isn’t muted. Browsers only allow sound after you interact with the page, which pressing Start does. Some phones silence web audio when the screen locks.
