How to use the online alarm clock

While you wait for the mobile post office to reach the village, set the alarm for 6:35 pm and keep an eye on the lane without checking the clock every minute. The alert marks the appointed moment, leaving enough time before 7:00 pm to collect your letters, documents or banking card and get to the usual stopping place.

A quiet setting may suit a peaceful room where you are already listening for the van, while a more insistent sound makes sense if the television, kettle or conversation could mask a gentle chime. Choose a tone you will recognise immediately, then set the volume for the surroundings rather than simply making it loud. Keep this browser alarm running and the computer awake: otherwise the post office may arrive and leave without the alert sounding.

Waiting near a window at 6:35 pm can mean looking between a bright screen and softer late-afternoon light outside. Reduce the display brightness until the clock remains clear without glowing across the room, and place the screen slightly away from your direct view of the road. A brief glance will then confirm the time while your attention stays on the village stopping point.

Common questions

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.

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.
