How to use the online alarm clock
Breaking off halfway through what you are doing can make meeting the last train at the station feel rushed, so an alarm for 1:04 am gives you a firm moment to stop and gather your things. It leaves a useful margin before 2:00 am for putting on a coat, checking the platform details and allowing for a quiet late-night journey across town.
Because this reminder depends on the browser remaining active, its behaviour matters as much as the selected time. If the browser is closed or the computer goes to sleep, the station alarm will not sound, which could leave you working past the moment you meant to leave. Keeping the alarm page open and the sound audible makes the 1:04 am signal available while you finish, without relying on it after the browser session has ended.
Leaving for the last train is easier with a drink already finished and no meal still being prepared. Water or a modest warm drink suits the wait before 1:04 am; a large late-night meal is more practical after the journey, when there is no platform deadline. If taking something along, choose a sealed bottle and a simple snack that will not slow down packing or create a nuisance in the carriage.
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 1:04 am?
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.
