How to use the online alarm clock
While you watch the clock for your lunchtime walk along the canal, an alarm at 1:48 pm can mark the moment to leave without another anxious time check. It also gives you a little breathing room before 2:00 pm, whether you need to fetch a coat, refill a water bottle or lock your desk before stepping outside.
Your canal walk depends on hearing the alert, so check whether your phone is on silent before relying on the browser alarm. The volume should be high enough for the signal to cut through nearby conversation, traffic or office noise. A short test alert can confirm the sound setting without disrupting the planned time. Keep another reminder available if leaving promptly matters: the canal walk alarm cannot sound after the browser session has ended or while the phone is asleep.
Waiting indoors at midday can make a bright screen feel unnecessarily harsh, especially when daylight is already coming through the window. Once 1:48 pm is selected, leaving the display at a comfortable brightness and placing it slightly farther away reduces the temptation to stare at the changing digits. The alarm can handle the final wait while your eyes settle on the room, the view outside or whatever you are finishing before the walk.
Common questions
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.
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.
