How to use the online alarm clock
As you hand responsibility for the church hall to its caretaker, a 6:57 pm alarm can mark the moment for returning the keys and confirming that your part is finished. The final three minutes before 7:00 pm leave enough time to check the entrance, gather any belongings and meet the caretaker without making the handover feel rushed.
For this handover, the alarm needs to be audible rather than merely visible on the screen. The phone’s silent setting may suppress the sound, so checking the volume and allowing browser audio beforehand reduces the chance of missing it. The alarm page must also remain active and the phone awake; otherwise there may be no alert to prompt the return of the keys. A separate built-in phone alarm provides a sensible backup when timing matters.
Anyone still at home may notice an alarm sounding at this late-afternoon hour, especially if the phone has been left in a shared room. Keeping it nearby and choosing a moderate volume makes the alert clear to you without startling other people in the house. A brief label such as “hall keys” also lets someone understand the reason if they hear or see it before you do.
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.
