10 Hour Timer FAQs
Does the 10-hour timer show hours as well as minutes?
Yes. Long timers display hours, minutes and seconds (for example 09:59:59), so you can read the remaining time at a glance.
How do I use the 10 hours timer?
Press Start and the timer counts down from 10 hours. 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 10 hours?
10 hours is 600 minutes or 36,000 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.
