Going to bed for a 10:08 am alarm

  • Asleep by 12:53 am — 6 full sleep cycles, about 9 hours
  • Asleep by 2:23 am — 5 full sleep cycles, about 7 hours
  • Asleep by 3:53 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

As you finish opening the workshop beneath the railway arch and head away, a 10:08 am alarm can mark the moment to lock up and leave for your next errand. It keeps the departure separate from the jobs waiting inside, while still leaving a useful stretch of the morning before 11:00 am. Label the alarm with the reason, so the sound immediately means that the workshop has been secured.

Your workshop departure could easily be missed if the phone or laptop is set to silent, even when the alarm appears on screen. Check the device’s sound setting and volume beforehand, then keep the browser active while you work. If the browser is closed or the computer goes to sleep, the workshop alarm will not sound, so use a separate alarm clock or phone alarm when leaving at 10:08 am cannot slip.

Once the shutters are down, take water and a small, easy-to-carry snack if errands will keep you out through the rest of the morning. A flask of tea or coffee may suit the walk from the railway arch, but a full meal is usually simpler after the 10:08 am departure, when you have somewhere clean and settled to sit. Keep anything messy or needing cutlery for later rather than juggling it beside keys and tools.

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 10:08 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.
