How to use the online alarm clock
Watching the clock for your bank branch’s final appointment can make 3:30 pm feel surprisingly tense. Set the alarm for the moment you need to gather your documents, keys and bank card, rather than the appointment time itself. That leaves a clear half-hour before 4:00 pm for the journey and any queue at the counter.
Your bank visit could be missed if the alert plays through headphones that are lying in a pocket or connected in another room. Before relying on it, check the sound output shown on your phone or computer, disconnect unused headphones, and run a brief test while you are still watching the time. Keep this page open and prevent the phone or computer from sleeping: once the page is closed or the machine has gone to sleep, the browser alarm cannot sound for the appointment.
Leaving for a branch at 3:30 pm can mean stepping from strong afternoon heat into heavily air-conditioned premises, even on a changeable British day. Carry paperwork in a closed folder so warm hands or sudden rain do not leave forms damp, and keep a light layer handy if indoor air feels sharply cooler. Put the alarm early enough to collect these things without rushing, then check the branch’s stated closing time before setting off.
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 3:30 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.
