Online alarm clock for 8:57 pm
Finishing up before you leave for the neighbourhood patrol, you can use an 8:57 pm alarm as the signal to put away what you are doing and head out. Those final three minutes are enough to collect your keys, torch and reflective layer without starting another task. You will then be ready to meet the others at 9:00 pm rather than noticing the hour after they have gathered.
Because the patrol takes you away from the screen, keep the alarm page open while you prepare. Closing its tab or the browser can prevent the neighbourhood patrol reminder from sounding, and it may also stay silent if your phone or computer goes to sleep. The alarm therefore works while the page remains active and the device stays awake. Check the sound level before stepping away, especially if an evening programme or household noise could cover the alert.
Leaving at this point in the evening can make the rest of the night feel tightly packed, so allow a small buffer after the patrol instead of assigning the next job to the minute you expect to return. Keep anything needed later in one visible place before going out. That spare time can absorb a delayed handover, a longer route or a brief conversation with another volunteer, while still leaving room to settle back in before the next commitment that same day.
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 8:57 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.
