Going to bed for a 6:44 am alarm

  • Asleep by 9:29 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:59 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 12:29 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

You have only just woken at 6:44 am, and the guest breakfast is still entirely unstarted. Setting the alarm for this exact minute gives you a clear point to get out of bed, switch on the kitchen lights and begin the full spread. With 7:00 am approaching, those sixteen minutes can cover washing, dressing and gathering the first ingredients before cooking starts.

A full breakfast for guests depends on hearing the signal when you planned to begin, so check that the device will remain awake until 6:44 am. Set a volume that is audible from the bed rather than relying on the level used for evening browsing. If this page is closed or the device falls asleep, the alarm cannot sound, and breakfast preparation may start late. A separate alarm on your phone can provide useful cover if punctual service matters.

Guests arriving early may already have travelled some distance, while your own journey to the kitchen could be as short as crossing a landing or as long as driving to the property. At this hour, allow for dark residential streets, overnight roadworks and slower rural lanes. Put keys, shoes and anything needed for the trip beside the bed, then leave a small margin rather than treating 6:44 am as the moment to begin driving.

Common questions

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.

What happens if my laptop goes to sleep before 6:44 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.
