How to use the online alarm clock
You have only just woken at 6:48 am, so give yourself a moment to get fully upright before preparing to raise the canal bridge for the barge. The alarm can mark the point when you need to leave the warmth behind, check what is happening outside and be ready for the 7:00 am lift without rushing through the first decisions of the morning.
For a bridge opening, hearing the signal matters more than repeatedly checking the clock. Set the browser alarm for the time when preparation must begin, choose a clear sound and raise the volume enough to carry across the room. A sleeping phone can silence this browser alarm, which could leave the barge waiting at the canal bridge, so keep the phone awake and the alarm page running until it sounds. A separate physical alarm is a sensible backup when the lift cannot be delayed.
Canal surroundings may still be dim at this early hour, even when the sky is beginning to brighten. Before going to bed, place a torch beside your keys and leave an outside light ready if one is available near the bridge controls. At 6:48 am, avoid relying on a bright phone screen alone: using a steady nearby light makes locks, switches and the approach easier to see while your eyes adjust.
Common questions
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 6:48 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.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
