How to use the online alarm clock
Finish what you are doing, gather your library card and bag, and leave when the 3:43 pm alarm sounds. That gives you a clear stopping point for collecting your reserved books without letting the afternoon slip away. If you need a few moments to put things away first, 4:00 pm provides a natural later boundary.
Set the signal loud enough to stand out from conversation, music or household noise while you prepare to go. A quick sound check can reveal whether the chosen alert carries from the room where your phone will remain. Keep a separate phone alarm as a fallback: if the browser is no longer active or the phone sleeps, this alarm will not sound, and your library books could remain uncollected.
Before heading out for the books, check how the afternoon air feels rather than judging it through the window. Humidity can make a mild UK afternoon feel close, while a breeze may make the same temperature seem cooler. Choose a layer that is easy to carry indoors, and allow a moment at the library entrance for wet coats or umbrellas if the air suggests rain.
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 3:43 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.
