Waking up at 7:45 PM

A 7:45 PM alarm is the night-shift worker’s morning — the ring that starts a workday most people are just finishing. It also covers the pre-event nap, the rest before a night drive, and the “wake me before dinner” lie-down.

If this is your main sleep before a night shift, be asleep by 12:15 PM to fit five full 90-minute cycles, or by 10:45 AM for nine hours. Afternoon sleep runs lighter than night sleep, so finishing whole cycles matters even more.

Build yourself a fake dawn: on waking, switch every light on, open the blinds if there is still daylight, and get moving. Your body reads bright light as “morning” whatever the clock says — and that is exactly the message a night shift needs.

FAQ

How do I set an alarm for 7:45 PM?
Press Start above — the page counts down to the next 7:45 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 7:45 PM?
To get 7.5 hours of sleep (five full 90-minute cycles), be asleep by 12:15 PM. For a full nine hours, aim for 10:45 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.
