How to use the online alarm clock
Waking at 12:16 am gives you a quiet moment to get your bearings before setting off to meet the last train at the station. Check the departure details, allow time for the walk or drive, and gather your keys and coat while the house is still. If the train is due closer to 1:00 am, use the remaining time without drifting back under the duvet.
Your journey depends on the alert sounding after you have woken, so keep the browser alarm where you can hear it and leave the volume at a clear level. A phone or laptop that goes to sleep before 12:16 am may silence the alarm; if that happens, you could miss the last train. Connect it to power if needed, prevent sleep until the alert has sounded, and use a separate alarm as a backup for a time-sensitive departure.
Before leaving for the station, check how the air feels outside rather than judging it from the bedroom. British nights can be damp at this hour, and high humidity may make a mild temperature feel clammy while mist leaves pavements and platforms slick. A light outer layer and shoes with reliable grip are sensible; allow a little extra walking time instead of rushing across wet ground.
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.
