How to use the online alarm clock
While you wait for the appointed check, a 1:28 am alarm keeps the tide from slipping out of mind as you watch the minutes. It leaves a useful pause for checking the harbour information and gathering what you need before 2:00 am, without repeatedly looking at the clock or heading towards the quay too early.
For a quiet wait beside sleeping crewmates, the alarm can use a gentle tone that marks the moment without filling the room. If background noise, wind or an engine may mask it, a more persistent sound is the safer practical choice. The alarm cannot sound after the browser page is closed or the phone goes to sleep, which could leave the fishing boat waiting while the tide changes; keeping the page open and the phone awake avoids that outcome.
Before settling down to monitor the time at 1:28 am, arranging the nearby light can make the tide check less disruptive. A dim lamp placed within reach gives enough light for notes or harbour details while preserving the darkness beyond the window. Turning down a bright overhead fitting beforehand also reduces reflections on the glass, making conditions outside easier to see when the alarm sounds.
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 1:28 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.
