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.

Online alarm clock for 7:12 am

You are halfway through the morning jobs when the 7:12 am alarm tells you to break off and let the chickens out after sunrise. It gives you a clear cue to leave what you are doing, open the henhouse and check the garden run. Once they are settled, there is still time to finish a few practical jobs before 8:00 am.

Because the chickens depend on that cue, test the alarm earlier with a short trial and listen for the signal at the volume you intend to use. Keep this page active while you work nearby. If the browser is closed or your phone or computer falls asleep, the alarm may not sound, leaving the chickens waiting inside. A quick advance check also shows whether silent mode or a connected headset could make the signal easy to miss.

After the hens are out, use the cool part of the early morning to refresh their water and make sure shade will reach the run later. During a warm British spell, avoid directing a portable air conditioner straight towards the open henhouse merely to cool the area; a steady draught can make the birds avoid that space. Keep cooled indoor air for your own room and rely on shade, ventilation and fresh water outside.

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.
