Going to bed for a 10:13 am alarm

  • Asleep by 12:58 am — 6 full sleep cycles, about 9 hours
  • Asleep by 2:28 am — 5 full sleep cycles, about 7 hours
  • Asleep by 3:58 am — 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

While preparing your resident parking permit documents in advance, set the alarm for 10:13 am as a clear point to finish checking the application. That leaves the rest of the morning available for anything missing, such as proof of address, vehicle details or a council account login, well before 11:00 am arrives.

Your permit paperwork may be spread across emails, photographs and online forms, so leave the alarm visible while you gather everything. Check that the sound is audible, then keep the browser running and your phone or computer awake until 10:13 am; otherwise the resident parking permit reminder will make no sound. A separate phone alarm is sensible if the machine might sleep while you look for documents elsewhere.

Once the 10:13 am alarm sounds, allow a small buffer before whatever follows later that day instead of treating the whole morning as available. Use part of that margin to reread names, registration details and uploaded files, then note any reference number after submission. Keeping a little time uncommitted also helps if the council form rejects a file or asks for another detail.

Common questions

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.

What happens if my laptop goes to sleep before 10:13 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.
