4 Hour Timer FAQs
Will a 4-hour timer keep running if I close the laptop?
The countdown is calculated from your device clock, so it shows the correct remaining time when the tab is visible again. Browsers cannot play the alarm while the device is asleep or the tab is closed, so keep the device awake for important alerts.
How do I use the 4 hours timer?
Press Start and the timer counts down from 4 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 4 hours?
4 hours is 240 minutes or 14,400 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.
