How to use the online alarm clock
While watching the clock for the Caledonian Sleeper’s arrival at Euston, set the alarm for 7:33 pm so the appointed moment does not slip past. There is still time before 8:00 pm, but keeping the alert tied to the exact minute lets you focus on the departure board and where you need to stand rather than repeatedly checking your phone.
Euston can be full of rolling suitcases, announcements and idling engines, so choose a signal you can hear clearly and raise the media volume before relying on it. Test the sound once in the surroundings where you will wait; a tone that seems loud in a quiet room may disappear into station noise. If the browser session ends or the handset falls asleep, the alarm cannot sound, which could leave you unaware that it is time to meet the train.
Waiting at 7:33 pm may involve moving between a brightly lit concourse and a darker pavement or platform area. Set your screen brightness before settling down, keeping it high enough to read the alarm controls without glare becoming distracting. Position yourself near steady lighting rather than directly beneath a harsh display, then glance at the time without losing sight of arriving passengers.
Common questions
What happens if my laptop goes to sleep before 7:33 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.
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.
