How to use the online alarm clock
While you wait to leave for the neighbourhood patrol, a 7:34 pm alarm lets you watch the clock without repeatedly checking whether the appointed moment has arrived. There are 26 minutes before 8:00 pm, enough time to gather a torch, keys and a light layer while remaining ready to head out at the agreed time.
Your patrol reminder depends on this page continuing to run in the browser. If you close the tab or browser, the alarm will not sound; it also cannot alert you if your phone or computer goes to sleep. Leaving the page visible and keeping the device awake avoids a silent departure time. Set the volume beforehand, then check that notifications and sound are permitted, particularly if the phone has recently been on silent.
Before an evening patrol in warm weather, moving straight from strong air conditioning into lingering outdoor heat can feel uncomfortable. Spending the last few minutes in a less heavily cooled room makes the change gentler, while a small bottle of water is practical for the walk. At 7:34 pm, pavements and brickwork may still be holding warmth even after direct sunshine has faded, so a breathable top with a light extra layer suits changing conditions.
Common questions
What happens if my laptop goes to sleep before 7:34 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.
