Frequently Asked Questions
How many minutes are in 8 hours?
8 hours is 480 minutes, or 28,800 seconds.
Does the timer keep running in a background tab?
Yes. The timer keeps exact time while you use other tabs or apps and rings when the time is up. Keep this tab open, and on a phone keep the screen on so the browser can play the alarm.
Can I change the time?
Yes. Pick another preset or type your own hours, minutes and seconds under the timer.
Will the timer ring if my computer goes to sleep?
Not while it sleeps: a sleeping device pauses the browser, so the alarm rings when it wakes up. For long timers, plug in your device and keep it awake.
