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 preparing a full breakfast for the guests and head away from the kitchen, set the alarm for 6:59 am so the final handover does not slip your mind. With 7:00 am arriving almost immediately, the alert can mark the moment to leave the last hot dishes ready, check that everything is covered and move on to your next morning task.

A guest breakfast may need a discreet reminder if others are already awake nearby, while a busy kitchen can swallow a gentle chime. Choose a softer tone when the room is quiet, or a more persistent sound when fans, kettles and conversation are likely to mask it; set the volume accordingly and test it once. Keep the browser running until the alert sounds, because otherwise the breakfast handover could pass without any warning.

Leaving a warm kitchen this early can make the surrounding air feel unexpectedly cool, especially where the air conditioning has been running overnight. Before walking into a chilled corridor or reception area, pause briefly away from the ovens and take a light extra layer if needed. At 6:59 am, that small adjustment can make the change from breakfast preparation to the cooler part of the building less abrupt.

Common questions

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 6:59 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.
