How to use the online alarm clock
Preparing the night before for the first train to London makes a 6:22 am alarm much less of a gamble. It leaves 38 minutes before 7:00 am, enough for getting dressed, collecting a packed bag and reaching the station without turning the morning into a rush. Tickets, keys and a travel card can all be left together beforehand.
For this early departure, the alarm needs to be audible in the room where it will sound. A quick test at the chosen volume reveals whether a fan, radio or traffic outside masks the tone; placing the computer nearby also helps keep it distinct from background noise. The browser alarm cannot protect the train plan if its page is no longer running or the computer has gone to sleep, because no signal will sound. A separate backup alarm is sensible when missing that service would disrupt the journey.
A pre-dawn start for London often means checking the screen while the room is still dark. Lower brightness and a warmer display setting can make the alarm controls easier on the eyes at 6:22 am, while a small bedside lamp avoids the sharp contrast of a bright screen against darkness. Once the time has been confirmed, leaving the display alone until the alarm sounds keeps unnecessary early-morning light to a minimum.
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 6:22 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.
