Waking up at 8:45 AM

The 8:45 AM alarm is a remote-work special: no commute to survive, just enough runway to make coffee and look alive for the 9:00 stand-up. Its danger is its comfort — with only fifteen minutes of slack, a single snooze puts you on camera with pillow lines.

An alarm at 8:45 AM is the workhorse of wake-up times — late enough to be sustainable every single day, early enough that the morning does not disappear before your first commitment.

For a 8:45 AM wake-up, count backwards to plan the night: asleep by 1:15 AM gives you 7.5 hours — five complete sleep cycles — while 11:45 PM buys you a full nine. Waking at the end of a cycle instead of the middle is the difference between surfacing naturally and being dragged out of deep sleep.

The biggest threat to a 8:45 AM alarm is the snooze spiral. Every tap buys nine minutes of fragmented, low-quality dozing that makes you groggier than just getting up. Commit to standing on the first ring, then get light on your face within a few minutes — it shuts down melatonin and tells your body the day has started.

FAQ

How do I set an alarm for 8:45 AM?

Press Start above — the page counts down to the next 8:45 AM 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.

What time should I go to bed to wake up at 8:45 AM?

To get 7.5 hours of sleep (five full 90-minute cycles), be asleep by 1:15 AM. For a full nine hours, aim for 11:45 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. 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.
