How to use the online alarm clock

Being halfway through another task makes a 2:50 pm alarm useful: it creates a clear break for checking the departure board before an intercity train. The signal leaves ten minutes before 3:00 pm, enough time to stop what you are doing, confirm the platform and notice any late change without repeatedly looking at the clock.

For a departure-board check, the alarm needs to be audible above conversation, station announcements, music or traffic outside. The browser signal follows the volume available on the phone or computer, so a quiet setting can make it disappear into background noise. A quick sound check beforehand shows whether the level is suitable. The departure-board reminder will not happen if this page has been closed or the phone or computer is asleep, so another alarm is sensible when missing the check could affect the journey.

Heading towards the station around 2:50 pm can feel quite different depending on the dampness outside. British midday air may be mild yet humid, making a brisk walk with luggage less comfortable than the temperature suggests. Keeping a light layer easy to remove, rather than buried under tickets or belongings, makes the final stretch simpler if the air feels close.

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.
