How to use the online alarm clock

As you finish checking the sheep and turn back towards the gate, a 3:37 pm alarm can mark the moment to leave the field before the fog thickens. It gives you a clear stopping point without waiting until 4:00 pm, when fading visibility may make the route across uneven ground harder to follow.

Once the final sheep is accounted for, the alarm page can remain open while you check a map or send a quick message in another tab. Browsers sometimes reduce activity on pages left in the background, so return to the alarm shortly before 3:37 pm and keep the sound switched on. If the browser is closed or the phone or laptop falls asleep, however, the sheep-check alert may never sound; use a separate alarm when missing it would leave you out in worsening conditions.

On the walk back from the flock, notice whether damp air is settling on gates, grass and your outer layer. Humidity can make the late afternoon feel raw even before the temperature drops, while fog may soften landmarks surprisingly quickly. Keep a dry layer handy, use the firmest familiar path, and wipe moisture from a torch lens before it is needed.

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 3:37 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.
