How to use the online alarm clock

While preparing for the early drive to Newlyn fish auction, set the alarm for 2:33 am before packing your keys, warm layer and paperwork. That leaves a quiet 27-minute margin before 3:00 am for getting dressed, checking the route and leaving without turning the departure into a last-minute scramble.

Your Newlyn departure depends on the alert remaining able to sound through the night, so keep the browser alarm running and prevent the phone or computer from going to sleep before 2:33 am. If the browser session stops or the machine sleeps, the fish auction alarm will not ring, and the planned head start may disappear. Leave the sound level clearly audible, connect the charger if needed, and use a separate clock as a fallback when missing the departure would disrupt the morning.

Getting ready for Newlyn in the middle of the night is easier when the room stays dim but usable. Keep the screen brightness low while checking the alarm, then put the display face down or beyond easy reach so its light does not fill the room. At 2:33 am, switch on a small lamp before looking at directions or documents; a gentler transition from darkness makes the practical details easier to handle before heading outside.

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 2:33 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.
