Going to bed for a 10:38 am alarm

  • Asleep by 1:23 am — 6 full sleep cycles, about 9 hours
  • Asleep by 2:53 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:23 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

As you finish what you are doing and prepare to leave, set the 10:38 am alarm so the milk delivery is not left waiting at the door. It gives you a clear cue to collect the bottles, put them away and head out without repeatedly checking the clock. With 11:00 am approaching, there is still room to deal with the doorstep handover without letting it take over the rest of your morning.

Because this alert matters at a precise moment, test its sound now rather than discovering a problem when the driver arrives. Set a temporary alarm for a minute ahead, check that the volume is clearly audible from the hallway, then return the timer to 10:38 am. Keep the browser alarm active and the computer awake; otherwise the milk delivery alert will not sound, and you could leave before noticing anyone at the door.

Once the bottles are indoors, treat the remaining morning as a buffer before your next commitment that day. Allow a few minutes for putting the milk in the fridge, returning empties and checking that the doorstep is clear. That small margin keeps a brief delivery from making you rush into whatever follows, while the approach to 11:00 am provides a natural point for moving on.

Common questions

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

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.
