How to use the online alarm clock
Getting ready early to meet the Caledonian Sleeper at Euston gives you room to check the arrival platform, your route to the station and any service updates without rushing. Set the alarm for 7:45 pm now, while the plan is still clear; the quarter-hour before 8:00 pm can cover those final checks and leave a little margin for getting out of the door.
Because the alert is meant to cut through evening distractions before the train arrives, check your phone’s sound setting after setting the time. Silent mode may prevent an audible alert even when the alarm itself is ready, so choose a volume you can hear and use vibration as a useful extra. Keep the browser page open and the phone awake: otherwise the alarm cannot sound, leaving you at risk of missing the train at Euston.
Preparing to leave for Euston at 7:45 pm may affect people who are settling down elsewhere in the house. Put your coat, keys and travel card together earlier, and keep the phone close enough that a moderate alarm volume will reach you without carrying through every room. If someone is already asleep, vibration on a hard bedside surface can be surprisingly noticeable, so place the phone on something softer and rely on a clearly audible but restrained tone.
Common questions
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.
What happens if my laptop goes to sleep before 7:45 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.
