How to use the online alarm clock

Preparing early for a stocktake at the village pub means setting the 12:18 pm alarm before counting begins. That leaves the remaining midday jobs clearly separated from the main check, while 1:00 pm provides a natural point for reviewing what has been recorded, resolving unclear figures, or handing the task over.

A trial signal earlier in the day confirms that the volume can be heard from the cellar, storeroom, or bar rather than merely looking active on screen. The chosen sound should be tested under the same conditions expected during counting, including ordinary pub noise. Because this browser alarm cannot sound after its page is closed or the computer has gone to sleep, the pub stocktake could begin late unless the alarm remains active on an awake machine.

During a midday pub check, sound can travel beyond the room where bottles and supplies are being counted. If other people are at home above or beside the premises, keeping the computer nearby allows a moderate alert to work without filling the house. A brief warning beforehand also prevents the 12:18 pm signal from being mistaken for somebody else’s reminder.

Common questions

What happens if my laptop goes to sleep before 12:18 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.
