Going to bed for a 6:12 am alarm

Asleep by 8:57 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:27 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:57 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

Before handing the kitchen over, set the 6:12 am alarm so the next person can begin preparing a full breakfast for the guests on time. Leave a clear note about what is already done and what still needs cooking, especially if service starts around 7:00 am. That gives the incoming shift a useful marker without relying on a hurried verbal handover.

During a breakfast handover, check where the alarm sound will actually play before leaving the kitchen. Wireless headphones may still be connected even when they are lying in a pocket or staff room, making the alert easy for the new cook to miss. Play a brief test, disconnect them if needed, and choose an audible volume. Keep the browser running and the computer awake: if either stops, the breakfast alarm will not sound for the person taking over.

A cook arriving at 6:12 am may move quickly between a warm kitchen and cooler guest areas. If the morning is already hot, set the air conditioning to a steady level rather than making a sharp change just before the handover. Keep the written breakfast notes away from vents, where loose sheets can shift, and place the alarm screen somewhere visible from the main preparation bench.

Common questions

What happens if my laptop goes to sleep before 6:12 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.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.

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.
