Going to bed for a 5:54 am alarm

Asleep by 8:39 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:09 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:39 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 hand the early shift over, use the 5:54 am alarm to mark when the garden gates should be opened for work on the vegetable beds. Tell the next person what remains locked and where the key is, so the handover is clear before 6:00 am. The alarm then acts as a shared checkpoint rather than a vague promise to do it shortly.

A handover at the garden entrance can fail quietly if the phone has been left on silent mode. Check the sound setting and volume, then use the alarm’s preview if one is available; a visible countdown alone may not catch the next person’s attention. Keep the alarm page running and the phone or computer awake until 5:54 am: if either stops, the alarm will not sound and the gates could remain shut.

Once the replacement has taken the key, keep the minutes after opening free for a quick check of the entrance, latch and path to the beds. Early light can make a dropped padlock or muddy obstruction easy to miss, especially during a rushed changeover. Leaving a small buffer before the next job that morning means a minor snag can be handled without pushing the rest of the day behind.

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 5:54 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.
