How to use the online alarm clock

As you hand the remaining work to a colleague or finish your shift, set the alarm for 4:31 pm so the last bank appointment does not slip your mind. It gives you a clear point to leave, collect any paperwork and head out before the branch’s final appointment window. With 5:00 pm approaching, that prompt can separate a calm handover from noticing the time after you should already be travelling.

A bank appointment may need a discreet reminder if other people are still working nearby, so choose a softer tone when a gentle nudge will be enough. If you are likely to become absorbed in explaining the handover, use a more persistent sound that is harder to miss. Test the volume briefly before relying on it. The alarm for your bank appointment will not sound if this page is closed or your phone or computer goes to sleep, so keep both active until 4:31 pm.

Before passing over the final task, check the route to the branch and note the realistic afternoon journey time, including school traffic, busy high streets or a delayed bus. Work backwards from the appointment rather than from the branch’s closing hour, then leave a small margin for finding the entrance or joining a queue. At 4:31 pm, roads can change quickly as the working day winds down, so an alarm is more useful when your coat, documents and travel plan are already sorted.

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 4:31 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.
