How to use the online alarm clock
While getting ready to unlock the hall for choir rehearsal, you can arrange a 9:32 pm alarm before it is needed. That leaves a useful margin for finding the keys, checking the booking details and reaching the entrance ahead of the singers. With 10:00 pm approaching, the signal can mark the moment to stop preparing and head out.
For a rehearsal evening, the alarm needs to be audible above music, conversation or a television playing nearby. Choose a suitable volume, then test it from wherever you expect to be waiting; a phone speaker that sounds clear in your hand may disappear beneath background noise across the room. Keep the browser active and the phone awake, because otherwise the signal may stay silent and the choir could arrive while the hall is still locked. A separate backup alarm is sensible if timing is critical.
The journey to open the hall at 9:32 pm may feel damper than an earlier evening trip, particularly after rain or beneath lingering cloud. Check the outdoor humidity and conditions before leaving, and allow a moment for misted glasses or a slippery pavement near the entrance. A light outer layer can be useful when moist air makes the short walk feel cooler, while arriving a few minutes early leaves time to unlock the door without rushing.
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.
