Going to bed for a 4:14 am alarm

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

Pause the kit check long enough to set an alarm for 4:14 am, so you can break away from what you are doing and leave for your shift at the London fire station. There are still 46 minutes before 5:00 am, but the precise alarm keeps that round hour from becoming an excuse to lose track while finishing the current job.

While you complete the remaining checks, leave this alarm page in the foreground if practical. Moving it behind another page does not cancel the time you entered, although a browser may restrict what a background page can do. Check that the alarm is still armed after switching back. Your shift cue cannot sound once its browser page is closed or the phone is sleeping, so use a separate alarm as backup before relying on it to leave.

Preparing for a fire-station shift at 4:14 am usually means looking at a bright screen in otherwise dark surroundings. Lower the display brightness before setting the time, use the phone’s warmer night setting if available, and keep a small lamp on nearby rather than staring at a sharply lit screen against complete darkness. Once the alarm is confirmed, place the screen face down so its glow does not keep pulling your attention from the final checks.

Common questions

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.

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.
