How to use the online alarm clock
You’re finishing what you were doing and getting ready to leave for the neighbourhood patrol, so an alarm for 8:03 pm gives you a clear moment to head out. It leaves enough evening before 9:00 pm to collect a torch, keys and a light layer without turning your departure into a rush.
Your patrol depends on hearing the alert before you walk away, so set the alarm while you are still near the phone and leave the browser running in the foreground. Check that the volume is audible over anything playing nearby. If the page is closed or the phone falls asleep before 8:03 pm, the patrol reminder may not sound, which could leave the others waiting at the meeting point. A separate phone alarm is a sensible backup when timing affects the group.
As you step outside for an evening patrol, the temperature change can be sharper than expected after sitting in air conditioning. Pause near the doorway for a moment, then choose a layer that suits the street rather than the cooled room. During a warm British spell, take water and avoid carrying unnecessary weight; on a cooler evening, a thin jacket can make a slow circuit more comfortable.
Common questions
What happens if my laptop goes to sleep before 8:03 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.
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.
