How to use the online alarm clock
Waking at 10:00 pm leaves you a little foggy, but the night engineering works timetable still needs checking before anything else begins. An alarm at this round hour can mark the moment to sit up, unlock your phone and confirm which Underground lines or stations are affected. Keep the relevant journey details nearby so you can read the notice without relying on half-remembered plans.
Your headphones may quietly keep control of the audio after you have put them down, making the alarm sound somewhere you are not listening. Check the output before settling back, then choose a clear volume that can be heard in the room without being jarring. The engineering works check could be missed if the browser is no longer active or the computer goes to sleep, so use a separate alarm clock when that timetable affects an essential journey.
Because this is late evening, allow a defined buffer before the next task you still need to finish tonight. Note how long the timetable check may take, add a few minutes for reading replacement-bus details, and leave the remaining time visible on a clock. That margin helps prevent a quick 10:00 pm check from quietly taking over the rest of the evening.
Common questions
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.
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.
