Going to bed for a 8:04 am alarm

  • Asleep by 10:49 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:19 am — 5 full sleep cycles, about 7 hours
  • Asleep by 1:49 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

Handing over the morning release means telling the next person that the chickens should go into the yard when the 8:04 am alarm sounds. That precise time avoids a vague “after sunrise” arrangement, while still leaving the keeper enough morning before 9:00 am to check the henhouse, water and gate once the birds are outside.

The handover can fail quietly if the alarm sound has been routed to headphones that nobody is wearing. A quick sound check beforehand confirms whether it will come from the phone or laptop speakers instead. The browser must also remain running and the equipment awake: if the page is closed or the phone or laptop sleeps, no alarm will sound, so the chickens may remain shut in after the agreed changeover.

Once responsibility has passed, the person going outside may find that early British air feels damp even without rain. At 8:04 am, moisture can linger on grass, latches and paving after a cool night. Shoes with a firm tread help around a slippery yard, and opening the henhouse from the side rather than leaning across wet ground makes the release steadier. A light outer layer is useful too, especially when the air is cooler than it seemed indoors.

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 8:04 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.
