A 11pm alarm is useful for a bedtime reminder, a wind-down routine or turning off screens.
For 8 hours of sleep before a 11:00 PM alarm, go to bed around 3:00 PM. Remember that online alarms cannot ring if your computer sleeps or the browser is closed, so plug in, keep the lid open, and switch on Keep screen awake.
Frequently asked questions
How do I set an alarm for 11:00 PM?
Press Set alarm on this page. It is already set to 11:00 PM. You can change the sound or add a label first.
Will the 11:00 PM alarm work if my laptop is closed?
No. Closing the lid usually puts the computer to sleep, which stops all sound. Leave it open and plugged in, or use a phone alarm as a backup.
Is TimerTab free?
Yes. Every clock, timer and alarm is free, with no account and no download. It works in any modern browser on desktop, phone or tablet.
Will it keep time if I switch tabs?
Yes. TimerTab counts from the real clock time instead of counting ticks, so it stays accurate when the tab is in the background and catches up instantly when you come back.
Does it work offline?
Yes. After your first visit the pages are cached on your device, so timers, the stopwatch and alarms keep working without an internet connection.
