Going to bed for a 7:12 am alarm

Asleep by 9:57 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:27 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:57 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 letting the hens out after sunrise and leave the yard at 7:12 am, the alarm can mark the moment without interrupting the rest of your morning. Set it for this exact time if the coop routine needs a firm endpoint before breakfast, the school run or work. You then have 48 minutes before 8:00 am, enough to wash up and put away anything used outside.

With clucking, a rattling gate and nearby traffic around the run, check that the alarm is loud enough to stand apart from the background noise. Keep the phone or computer close instead of leaving it inside behind a closed door, and test the signal while the yard sounds as it normally does. If the browser is closed or the equipment falls asleep, the alarm will not sound, so the hens’ release should not depend on it unless the page stays open and the equipment remains awake.

Before leaving the coop the previous evening, place a torch where it can be reached without searching and clear the approach to the latch. At 7:12 am, a British morning may still be dim beneath cloud even after sunrise, particularly in winter. Position an outside light to illuminate the path rather than shine directly into the henhouse, making it easier to check the gate and see that every bird has moved safely into the run.

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 7:12 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.
