Going to bed for a 4:44 am alarm

Asleep by 7:29 pm — 6 full sleep cycles, about 9 hours
Asleep by 8:59 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:29 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

Break away from what you are doing when the 4:44 am alarm sounds, so you can get ready to begin your Coastguard shift. That leaves a short, practical window for pulling on warm layers, checking your kit and reaching the station before 5:00 am, rather than letting the activity in front of you run on unnoticed.

Your Coastguard shift needs a separate backup alarm, because this browser signal only works while the browser remains active and the computer or phone stays awake. Before returning to your current task, raise the volume and test the sound once. Background noise from a kettle, shower, radio or equipment can mask a quiet alert, so place the phone nearby and choose a level that is clearly audible from where you will be.

Protect the sleep that remains before 4:44 am by preparing your clothes, keys and Coastguard kit earlier in the evening. Keep the room dark and leave only the essentials beside the bed, reducing the amount you need to think about during a night-time wake-up. Once the alarm ends your rest, switch on a low light, drink some water and move straight into the routine you prepared.

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 4:44 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.
