How to use the online alarm clock
You have just woken up, and meeting the excursion boat by the canal lock is still only a plan. Setting an alarm for 12:41 pm gives the departure a firm place in your day before you start getting dressed, checking the route or gathering what you need. With 1:00 pm approaching, there is enough structure to move from bed to the towpath without letting a slow midday start take over.
Your excursion boat is a poor occasion for discovering that the signal is too quiet. Set the browser alarm, then test it straight away at the volume and distance you expect to use; a brief trial can reveal muted audio or a sound that disappears beneath household noise. If the browser page is closed or the handset falls asleep, the alarm cannot sound, leaving you at risk of missing the boat. Keep the page running and use a separate phone alarm as backup when timing matters.
Heading towards a canal lock around midday can feel muggy, especially beside still water and sheltered brickwork. Check the local humidity before leaving, choose a breathable outer layer, and allow a moment for the outdoor air after coming from a warm room. Carrying water and keeping any rain layer easy to reach can make the walk more comfortable without adding a lengthy stop.
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 12:41 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.
