Waking up at 11:15 PM

A 11:15 PM alarm is a specialist’s tool — a night-shift start, a flight to catch, a deadline on the other side of the world, or a short sleep wedged between two halves of a long day. It works, but it deserves backup: set a second alarm five minutes later until the routine is proven.

Sleeping toward 11:15 PM? Count cycles, not hours: asleep by 3:45 PM completes five, and even a single 90-minute cycle beats an hour of fragmented dozing. Set the alarm before your head hits the pillow — nobody does arithmetic well in the dark.

When it rings, act fast — darkness invites the return to sleep. Light on before anything else, then stand up. If you are staying up, find the brightest light you can; if this is a brief interruption, do the opposite and keep everything dim.

FAQ

How do I set an alarm for 11:15 PM?
Press Start above — the page counts down to the next 11:15 PM and plays a loud beep through your browser. Keep this tab open and your volume up. No download or signup needed.
What time should I go to bed to wake up at 11:15 PM?
To get 7.5 hours of sleep (five full 90-minute cycles), be asleep by 3:45 PM. For a full nine hours, aim for 2:15 PM. Add about 15 minutes for actually falling asleep.
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. For alarms that ring reliably even over the lock screen, use the AVA app.
