Going to bed for a 5:22 am alarm

Asleep by 8:07 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:37 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:07 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 parking move to the next person, set the alarm for 5:22 am and make clear which car must leave the overnight zone. That gives them a definite cue rather than a vague promise to move it before 6:00 am, when morning restrictions or ordinary street activity may begin.

Because the alarm is part of the handover, check its sound now, while both people can confirm that it is loud enough and the selected time is correct. Keep the page available and the phone awake until 5:22 am: if the page is closed or the phone sleeps, the alarm may not sound, leaving the car in the overnight parking zone. A separate phone alarm is a sensible fallback when nobody will be watching the screen.

On the walk back from the parking zone, keep the display dim and avoid staring at a bright white screen in the early darkness. Increase the text size if the alarm details are difficult to read, then put the phone somewhere audible without repeatedly checking it. At 5:22 am, that reduces glare for tired eyes while still making the handover information easy to see.

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 5:22 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.
