How to use the online alarm clock
Pause what you are doing at 8:41 pm and use the alarm as the cue to break away and get ready for your neighbourhood patrol. It gives you a clear stopping point before the evening slips on unnoticed. There is enough room before 9:00 pm to finish the immediate bit of your task, collect your keys, torch and reflective layer, then leave without rushing.
Because the patrol depends on you noticing the alert, keep this page open after setting 8:41 pm and leave your phone or computer awake. Closing the page or browser, or allowing the device to sleep, may prevent the alarm from sounding and could make you late for the patrol. Check that the volume is audible over whatever you are doing, and keep the device close enough that the signal will actually interrupt you.
Before stepping outside on an evening round, reduce the screen brightness once your route details are checked. A bright display can feel harsh against darker streets and can make it harder to see your surroundings immediately after looking away. Use a dim setting while gathering your things, avoid repeatedly checking the screen, and let the 8:41 pm alarm be the final prompt rather than keeping the display lit until departure.
Common questions
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
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.
