How to use the online alarm clock

You are halfway through preparing the printed forms for the morning newspaper edition when 12:18 am arrives, so the alarm marks the moment to break away from the layout rather than merely check the clock. It leaves a useful stretch before 1:00 am for reviewing what is already on the press schedule and noting anything that still needs attention.

Printing equipment, ventilation and late-night newsroom activity can easily mask a quiet signal. The alarm volume should therefore be checked against the actual background noise, with a clear tone chosen before returning to the forms. If the browser page is closed or the computer goes to sleep, no alarm will sound, and the newspaper forms may remain unfinished when the morning edition moves to its next stage.

Detailed forms on a bright screen can feel particularly stark against a dark room at this hour. A nearby lamp can soften the contrast without making small print harder to read, while slightly reducing screen brightness may make the final checks more comfortable. Placing the alarm display beside the working document also avoids repeated glances across multiple bright windows as 1:00 am approaches.

Common questions

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.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

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

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.
