How to use the online alarm clock
While you watch the clock for 4:19 pm, the sheep can stay undisturbed until the moment set aside for checking them before the fog thickens. An alarm at this exact time separates the planned inspection from the rest of the afternoon, while 5:00 pm remains a useful backstop for finishing the round or reassessing visibility.
Because this reminder depends on the browser continuing to run, closing the page or browser may silence the alarm and leave the sheep unchecked as the fog draws in. Keep the alarm page open and the phone or computer awake, with the sound turned up enough to hear from where you are waiting. A separate phone alarm is a sensible fallback if you expect to put the device away before 4:19 pm.
Before heading out that afternoon, move from strong air conditioning into the outdoor heat gradually rather than lingering indoors until the alarm sounds. Put water, a light layer and any checking gear near the exit so the change in temperature does not delay the sheep inspection. At 4:19 pm there is still daylight in much of the UK during the warmer months, but fog can quickly flatten contrast, so use the alarm as the point to check conditions as well as the flock.
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 4:19 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.
