How to use the online alarm clock

While you wait to meet the last boat from the Isle of Skye, set the alarm for 7:39 pm and keep an eye on the clock without checking it every few seconds. The signal gives you a clear moment to stop waiting and get into position for the arrival. There are 21 minutes between the alarm and 8:00 pm, enough for a short delay at the landing point without losing track of the evening.

Because the alert is needed at one exact moment, keep the browser running and prevent the phone or laptop from going to sleep beforehand. If the browser has been closed or the device has already slept, the alarm may not sound, leaving you without the warning needed for the last boat. Turn the volume up to a level you can hear over engines, wind or conversation, then leave the alarm page visible while you wait.

Once the boat has arrived, use the remaining part of the evening as a buffer before the next commitment that day. Note the latest sensible departure time from the harbour, allowing for dark roads, parking or a slower crossing than expected. That small margin after 7:39 pm helps keep one late arrival from pushing everything else back.

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 7:39 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.
