How to use the online alarm clock
As you finish what you are doing and leave to meet the sightseeing boat at the canal lock, a 1:14 pm alarm gives the departure a definite edge. There is enough room before 2:00 pm to gather your things, walk to the towpath and find the correct side of the lock without treating the whole 46 minutes as spare time.
For a reminder tied to the boat, hearing the signal beforehand is more useful than discovering a muted phone at the moment you meant to set off. Set the alarm, play a brief test and check that the volume is clear above any nearby conversation or traffic. Keep this alarm page open and the phone awake, because the boat reminder cannot sound after the browser is closed or the phone has gone to sleep.
A canal meeting around midday can leave another appointment, journey or household job later in the afternoon. Keep a small part of the time before departure untouched, then note how long the walk back from the lock is likely to take. That buffer helps prevent the 1:14 pm reminder from solving one timing problem while quietly creating the next one.
Common questions
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 1:14 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.
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.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
