How to use the online alarm clock

As you finish up and leave to meet the mobile post office in the village, set the alarm for 6:16 pm so packing away does not make you miss its arrival. The alert gives you a clear stopping point for your last job and helps you head out before 7:00 pm, with enough time to reach the usual stopping place without turning the departure into a rush.

Your meeting with the mobile post office depends on hearing the signal, so test the alarm once while there is still time to adjust the volume. Check that the sample sound is audible from where you will be working, especially if the phone will sit in a pocket or another room. A browser alarm cannot warn you about the mobile post office if the page has been closed or the phone has gone to sleep, so keep both active until 6:16 pm or arrange a separate phone alarm.

Leaving for the village in late-afternoon light can put a bright screen against dimmer surroundings. Lower the display brightness before setting off, enlarge any directions you need, and avoid repeatedly checking the countdown as daylight fades. At 6:16 pm, one quick glance should be enough to confirm the alert; putting the phone away afterwards lets your eyes stay with the lane, pavement and approaching vehicle.

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 6:16 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.
