Going to bed for a 5:02 am alarm

Asleep by 7:47 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:17 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:47 pm — 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 the last indoor jobs and head out to release the chickens after dawn, a 5:02 am alarm marks the moment to leave. It gives you a clear cue without tying the whole morning to 6:00 am, when feeding, water checks or other jobs around the holding may already need attention.

The sound has to reach you amid a humming boiler, running tap or movement near the back door, so set the alarm volume above the background noise and avoid relying on a faint tone. A quick sound check can reveal whether the selected alert carries into the next room. If this page is closed or the device goes to sleep, no alarm will sound, and the chickens may remain shut in when you meant to let them out.

Stepping into the yard at this early hour can mean meeting damp air, wet grass and moisture on gates or latches. Keeping a light waterproof layer and a small torch beside the door makes the short walk to the hen house less awkward. On humid mornings, allowing a little extra time for a stiff latch or slippery path helps the 5:02 am departure stay unhurried.

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 5:02 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.
