How to use the online alarm clock
You’re finishing what you are doing and heading out to meet an excursion boat beside the canal lock, so a 2:20 pm alarm can mark the moment to leave. That gives you a clear departure point without repeatedly checking the clock. If the boat is due closer to 3:00 pm, the alert also leaves room for the walk or drive and a few minutes to find the correct side of the lock.
Because reaching the lock depends on leaving promptly, keep the alarm page active while you finish up and make sure the sound is loud enough to notice. If your phone or computer falls asleep before 2:20 pm, the browser alarm may stay silent, which could leave you arriving after the excursion boat has passed through. A separate alarm on the device is a sensible fallback when you cannot keep it awake.
Your route to the canal can take longer in the early afternoon than the same journey earlier in the day. Check for roadworks, school traffic and limited parking near the towpath, then allow time to cover the final stretch on foot. Leaving at 2:20 pm rather than treating 3:00 pm as the departure time gives you a useful margin for a slow bus, a raised bridge or an unfamiliar lock entrance.
Common questions
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.
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.
