How to use the online alarm clock
While planning ahead to move your car before the parking restriction starts, set the alarm for 2:11 pm so you have a clear prompt rather than watching the clock. That leaves a useful window before 3:00 pm for finding your keys, checking the bay sign and getting outside without turning the job into a last-minute dash.
Because your phone may be on silent while you work or eat lunch, check its sound setting and raise the media volume enough to hear the alarm. A quick test alert can confirm the level without waiting until 2:11 pm. Keep this alarm page open and your phone awake; otherwise the alert may never sound and the car could remain in the restricted parking space.
Moving the car around midday can feel different depending on the weather, even when the walk is short. Check the outdoor humidity shortly beforehand and allow a little extra time if the air feels close or rain is hanging about. Having a light layer or umbrella by the keys means you can leave promptly at 2:11 pm instead of searching for something suitable while the parking deadline approaches.
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.
