Going to bed for a 5:05 am alarm

Asleep by 7:50 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:20 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:50 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

While you watch the clock for the moment to begin the sheep round on a Welsh farm, an alarm set for 5:05 am lets you wait without repeatedly checking the minutes. It marks a clear starting point while the yard is still quiet, with 55 minutes remaining before 6:00 am for the first part of the round.

Before heading towards the sheep, check where the alarm sound will play. Headphones left connected can take the alert without making it obvious to anyone nearby, especially if they are under a coat or lying in another room. Disconnect them or test the volume through the intended speaker, then leave the browser running and the computer awake. Otherwise, the sheep round may start late because this browser alarm cannot sound once that active session is interrupted.

If 5:05 am falls between two periods of sleep, prepare everything needed for the farm round before lying down: boots by the door, warm layers together and a torch within reach. That keeps the remaining sleep from being shortened by searching in the dark, and it makes the early start quieter for anyone else in the house.

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 5:05 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.
