How to use the online alarm clock
Break away from sorting the boat gear at 2:53 am and use the alarm as the cue to check the tide before the fishing boat leaves. That keeps the forecast, harbour conditions and departure decision together rather than relying on a glance at the clock. With 3:00 am approaching, the seven minutes provide a clear point to pause the job and make the check.
Match the alarm sound to what is happening around the boat. A softer tone may be enough in quiet accommodation or a still wheelhouse, while a more persistent sound suits noisy preparation where engines, running water or moving equipment could mask it. Set the volume before returning to the gear, and leave the alarm somewhere audible. Because a browser alarm cannot sound once its page is closed or the phone falls asleep, the tide check needs a separate backup if missing it could delay the boat.
Stepping outside for the 2:53 am check can feel noticeably damper than the air indoors, especially near a British harbour. Keep a dry outer layer beside the gear and allow a moment for glasses or a screen to clear if moisture forms. That small preparation makes tide figures easier to read without bringing wet hands back to the remaining work.
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 2:53 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.
