How to use the online alarm clock
As you hand over responsibility for meeting the last train at the station, set the alarm for 12:03 am and tell the next person exactly what it marks. That leaves a clear reference point before 1:00 am, whether they are taking over the journey, watching for the arrival board to change, or waiting near the platform entrance. A brief note beside the alarm can prevent confusion about which train and meeting place you mean.
While the station plan passes to someone else, the alarm may be left running behind the page they are checking. A browser can reduce activity on a page that stays in the background, so the sound should be tested after switching away and returning. Keep the browser session running: if it is ended or the computer goes into standby, the train reminder will not sound. For a handover, a separate phone alert gives the other person a useful fallback.
Waiting for a final train after midnight can feel quiet until an announcement, cleaning trolley or arriving service suddenly masks a notification. At 12:03 am, use a clearly audible tone rather than relying on a subtle chime, and keep the screen where its visual alert can also be noticed. Moving a little away from loudspeakers makes changing station noise less likely to hide the alarm.
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 12:03 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.
