Going to bed for a 11:04 am alarm

  • Asleep by 1:49 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:19 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:49 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

With bags of garden cuttings partly sorted, you need to break away from the job at 11:04 am and start loading the car. The alarm marks that exact stopping point, so tidying one more corner does not quietly turn into another half-hour. Leaving then also gives you a useful stretch before 12:00 pm to check the containers and secure anything loose for the journey to the council recycling centre.

A half-loaded car makes a missed signal especially awkward, so the alarm needs to remain able to sound while you finish outside. After setting 11:04 am, check that the volume is audible and prevent the phone or laptop from falling asleep before the alert. If the browser page is closed or the device sleeps, no alarm will sound, which may leave the garden waste waiting on the drive instead of heading to the recycling centre.

Once the recycling run pulls you out of late-morning sleep, protect whatever rest you plan to have afterwards. Put clean bedding or comfortable clothes within reach before leaving, keep the bedroom shaded, and avoid adding unnecessary errands to the return trip. At 11:04 am, daylight and household noise can make settling back down less straightforward, so having the room ready gives the remaining sleep a clear place in the day rather than treating it as spare time.

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 11:04 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.
