Going to bed for a 10:58 am alarm

  • Asleep by 1:43 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:13 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:43 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

Handing the primary-school run to someone else this morning means making the change clear before they set off. An alarm for 10:58 am can mark the moment to pass over the child’s bag, coat and any message for the teacher. That leaves a brief, useful margin before 11:00 am for confirming who is collecting later.

Because the school handover depends on this reminder, leave the alarm page open after setting it and keep the browser running. If the page or browser is closed, or the phone goes to sleep, the alarm may not sound and the school arrangement could be missed. Check that the volume is audible, then keep the phone somewhere the person taking over can hear it rather than buried beneath coats or inside a packed bag.

Whoever takes the child out near the end of the morning may find the air feels damper than it did earlier, especially after drizzle or beneath lingering cloud. At 10:58 am, check the conditions at the door and allow a moment for a light waterproof layer if the pavement is still wet. In muggy air, carrying an extra layer rather than wearing it straight away can make the walk to primary school more comfortable.

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 10:58 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.
