How to use the online alarm clock
Waiting to hand the church hall keys to the caretaker, you can set the alarm for 5:46 pm and keep an eye on the time without repeatedly checking the clock. The handover still leaves 14 minutes before 6:00 pm, which may be useful if the caretaker is finishing another job nearby.
For a quiet hall where people may still be packing away chairs or talking, a gentle tone can mark the agreed moment without jolting everyone. A more insistent sound suits a noisy clear-up or a phone tucked inside a coat pocket. The selected alarm will sound only while the browser remains active and the phone stays awake; otherwise the keys handover could pass without an audible reminder.
Before waiting outside with the keys, consider how the late-afternoon air actually feels rather than relying on the temperature alone. Britain’s damp air can make a mild reading feel chilly when standing still, especially near an unheated entrance. A light layer that is easy to remove may be useful, and sheltering the keys from drizzle avoids presenting the caretaker with a wet keyring at 5:46 pm.
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.
