How to use the online alarm clock
Waking at 5:33 pm, you are still under the duvet while the books reserved for you are waiting at the library. An alarm now gives you a clear point to get up, dress and check the branch’s collection hours. With 6:00 pm approaching, there is enough structure for a quick departure without letting the rest of the afternoon drift away.
Your library collection may depend on hearing the signal over a television, extractor fan or other background noise. Choose a volume that is distinct from the sounds already filling the room, then test it once before relying on it. The alarm can only support this library trip while the browser page remains open and the phone or computer stays awake; otherwise, no signal will play when 5:33 pm arrives. A separate phone alarm is sensible if you might fall asleep again.
Stepping outside after an afternoon sleep can feel different from the room you have just left, particularly when the British air is damp. Check the humidity or current conditions before dressing, as a light layer may be useful even if the temperature looks mild. If rain has recently passed, allow for slower pavements and keep the library books protected on the journey home.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
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.
