Waking up at 11:45 AM

An alarm at 11:45 AM is often a backstop — for the day after a red-eye, the recovery sleep after a brutal week, or a deliberately slow weekend morning. Nothing wrong with that; sleep debt is real, and this is how it gets repaid.

If you are heading to bed now and need to be up at 11:45 AM, be asleep by 4:15 AM for 7.5 hours or by 2:45 AM for a full nine. If it is a power nap you are after, twenty minutes is the sweet spot — set the alarm and trust it.

One caution: sleeping this late regularly pushes your body clock later, which makes the next early morning harder. If 11:45 AM is a one-off, enjoy it. If it is every day, keep it consistent — a stable schedule matters more than an early one.

FAQ

How do I set an alarm for 11:45 AM?
Press Start above — the page counts down to the next 11:45 AM 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 11:45 AM?
To get 7.5 hours of sleep (five full 90-minute cycles), be asleep by 4:15 AM. For a full nine hours, aim for 2:45 AM. 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.
