How to use the online alarm clock

Getting ready early to meet the mobile post office means checking its stopping place, gathering your letters and keeping any forms or identification by the door. Set the alarm for 6:05 pm before those small jobs distract you. That leaves a useful stretch before 7:00 pm if you need to walk across the village or put on a coat for changeable British weather.

For a village stop that may last only a short while, the alarm needs to remain able to sound until you leave. Do not rely on it after putting your phone away for the afternoon: it may stay silent, leaving you unaware that the mobile post office has arrived. Keep the browser alarm active and the phone awake, with the volume high enough to hear from the next room. A separate household alarm is sensible if you expect to leave the phone unattended.

While you wait to meet the mobile post office, have a light snack or a glass of water if supper is still some way off. Save a large meal for afterwards, as cooking and clearing up can absorb the part of the afternoon when you meant to collect your things and head out. Put a drink in a reusable bottle if the stopping point is a walk away.

Common questions

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 6:05 pm?

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.
