Waking up at 11:00 PM
An alarm set for 11:00 PM rarely means “good morning.” It is a night-shift wake-up call, the end of an evening nap before a late flight or a match in another time zone, or a hard reminder to take medication — or to actually go to bed.
Evening alarms fail differently from morning ones: the risk is not snoozing, it is sleeping straight through in a dark, quiet house. Turn the volume up, keep this tab in the foreground, and consider a second alarm a few minutes after 11:00 PM as insurance.
If you are waking at 11:00 PM for a night shift, protect your main sleep block during the day the way day-workers protect their nights: same hours, dark room, phone on do-not-disturb. The alarm is the easy part — the sleep before it is what gets you through the shift.
FAQ
- How do I set an alarm for 11:00 PM?
- Press Start above — the page counts down to the next 11:00 PM and plays a loud beep through your browser using the WebAudio API. Keep this tab open and your volume up. No download or signup needed.
- Will this alarm wake me from an evening nap at 11:00 PM?
- Yes — as long as the tab stays open and your volume is up. Evening sleep can be deep, so add a second alarm a few minutes after 11:00 PM as a backup, or use an app that rings even when the phone is locked.
- Will the alarm ring if my screen is off or the tab is closed?
- No — a browser alarm needs this tab open and the device awake. If the phone locks or the tab closes, the beep cannot play. For alarms that ring reliably even over the lock screen, use the AVA app.
