How to use the online alarm clock
Handing your duties to a colleague before taking part in a union meeting can make 12:47 pm easy to miss. Set the alarm for 12:47 pm so the handover ends when planned, leaving the remaining minutes before 1:00 pm for putting away work materials, finding the meeting room and joining the other members without rushing.
Because the union meeting depends on a prompt handover, check the alert while there is still time to correct a muted phone or low volume. Set a temporary alarm a minute or two ahead, listen for the sound, then restore 12:47 pm and keep the browser available. If the browser closes or the phone falls asleep, the union meeting alert cannot sound, so use a separate alarm when you cannot leave the page running.
Leaving a busy work area around midday may mean moving from machinery, customer conversations or a crowded staff room into a quieter corridor. Notice how the background noise changes along your route and choose a volume that remains audible at the loudest point. Keeping the phone nearby, rather than beneath paperwork or inside a locker, also makes the 12:47 pm signal easier to recognise without disturbing the whole workplace.
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 12:47 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.
