Going to bed for a 9:05 am alarm

Asleep by 11:50 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:20 am — 5 full sleep cycles, about 7 hours
Asleep by 2:50 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 MOT visit to someone else at 9:05 am is easier when the handover has a clear moment attached to it. Set the alarm for the agreed departure or key collection, then pass on the registration details, appointment time and workshop address. With 55 minutes before 10:00 am, there is enough space to explain any known warning lights or paperwork without turning the handover into a rush.

A reminder meant for an MOT handover is only useful if its sound is familiar before the keys change hands. Try the alarm once now, check that the volume is audible from where the phone or laptop will sit, and confirm that the chosen tone is distinct from ordinary notifications. This browser alarm must remain active and the phone or computer must stay awake; otherwise the MOT alert will not sound when the other person needs to leave.

Someone setting off for a workshop during the morning may step outside to find damp air, misted glass or moisture on the windscreen. Leave a few practical minutes for clearing the windows fully rather than driving with a narrow patch of visibility. At 9:05 am, the air can still feel humid after an overnight shower, so keeping a cloth handy and using the demister before departure makes the MOT handover calmer and clearer.

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.
