How to use the online alarm clock

As you finish what you are doing and head out for a mining-town brass band rehearsal, a 5:25 pm alarm can mark the moment to pack up and leave. That gives the journey, instrument case and any last-minute sheet music a place in the plan, without treating 6:00 pm as the actual departure time.

A rehearsal reminder is more useful when its sound has already been checked at the volume needed in the room. A brief test beforehand confirms that the chosen tone is audible above conversation or a radio, and that the browser has permission to play it. This rehearsal alarm will not sound if the browser stops running or the phone falls asleep, so it should not be the only cue relied upon for leaving.

Returning from band practice can push the evening later than expected, even though 5:25 pm still feels firmly like afternoon. Keeping tomorrow’s instrument, clothes and essentials together before setting off leaves fewer jobs for the return home. That preserves more of the night for sleep, particularly when an early shift or morning journey follows, while a planned wind-down after the rehearsal helps prevent small tasks from filling the remaining hours.

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.
