How to use the online alarm clock
While you watch the lane for the mobile post office, set the alarm for 4:41 pm so the appointed stop does not slip past while you are waiting. There are still 19 minutes before 5:00 pm, enough time to finish a small job indoors without losing track of the van’s expected arrival.
If you switch to a message or village notice, the alarm page may remain in the background, but some browsers reduce activity there. Check that sound is allowed and return to the alarm shortly before 4:41 pm. Keep the browser page running and the phone awake: otherwise the mobile post office may have come and gone before an alarm can sound. A quick volume check also prevents a quiet alert from being missed amid household noise.
Waiting near the roadside in the late afternoon can feel uncomfortable on a warm day, especially after leaving an air-conditioned room. Put anything you need for the mobile post office by the door, then stay inside where it is cooler until the alarm sounds. At 4:41 pm, step out with a hat and some water if the stop has little shade; this keeps the final wait practical without spending the whole 19-minute stretch in the heat.
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 4:41 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.
