Going to bed for a 7:43 am alarm

Asleep by 10:28 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:58 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:28 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

With the last newspapers through the letterboxes, you can set a 7:43 am alarm as the signal to leave the terrace and head off. It gives you a clear stopping point after the final house, while 8:00 am remains close enough to shape what comes next. Rather than lingering to recheck every gate, use the alarm to mark the handover from finishing the round to starting your journey home.

Terraced streets can be noisy even this early, with passing vans, bins being moved and front doors closing. Set the volume high enough to stand out from that background, then test the sound before relying on it. Keep the browser active and the screen awake until the signal plays; otherwise the newspaper round could end without the audible reminder you expected. Putting the phone in an outer pocket may also make the alarm easier to hear than if it is buried beneath papers or clothing.

Once the terrace is behind you, allow for the route to take longer near bus stops, school crossings and roads feeding commuter stations. Traffic can build quickly as 8:00 am approaches, so check the likely journey time before choosing whether to walk, cycle or drive. A familiar shortcut may save less time if delivery vans are stopping along narrow residential streets.

Common questions

What happens if my laptop goes to sleep before 7:43 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.

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.
