Going to bed for a 10:46 am alarm

  • Asleep by 1:31 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:01 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:31 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

While you watch the clock for the milk delivery at the door, an alarm for 10:46 am gives you a clear cue to head into the hall and listen for the knock. It also leaves 14 minutes before 11:00 am, enough time to bring the bottles inside and put chilled items away without losing track of the morning.

Keeping the delivery details open may push the alarm page into the background, but it can still sound while the browser continues to let that page run. Some browser or phone settings may pause a background page, so check that the alarm remains active after switching screens. If the browser closes or power-saving suspends it, the alarm cannot alert you to the milk delivery; keep it running and prevent the phone or computer from sleeping until the driver arrives.

Because the milk arrival affects everyone nearby, choose a volume that you can hear from the kitchen without startling someone working, sleeping after a night shift, or taking a call elsewhere in the house. At 10:46 am, placing the phone near the hallway rather than beside another person makes the signal useful where the door needs answering and less intrusive across the rest of the home.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 10:46 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
