How to use the online alarm clock
While you gather the books for the mobile library, a 10:02 am alarm can mark the moment to put them by the door, find your library card and check the scheduled stopping place. Preparing now leaves 58 minutes before 11:00 am, enough time to spot a forgotten return or separate anything that belongs on your own shelf.
For this library errand, the alarm needs to remain active while you finish getting ready. The time can be set for 10:02 am and the sound checked before the phone is put aside. If the browser stops running because the phone falls asleep, the alarm will not sound and the books may miss the mobile library visit. Keeping the browser active and the phone awake until the alert has sounded avoids relying on a reminder that cannot run in the background.
A late-morning library stop may put a bright screen against softer indoor light, especially near a window on an overcast British morning. Once the alarm is prepared, lowering the screen brightness to match the room makes the remaining checks less glaring. The phone can then rest at a comfortable distance instead of being held close while you wait, with the volume high enough to hear the 10:02 am alert without watching the display.
Common questions
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.
What happens if my laptop goes to sleep before 10:02 am?
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.
