How to use the online alarm clock
Waking at 2:27 am gives you a quiet moment to remember why you set the alarm: meeting the ferry from Belfast when it arrives in Liverpool. Before getting up, check the crossing details and confirm where you need to wait at the terminal. That leaves the approach to 3:00 am for dressing, gathering your keys and preparing to leave without a hurried search for anything essential.
For a ferry pickup in the middle of the night, set the volume high enough to cut through a fan, traffic outside or audio still playing on your phone. A quick test signal can show whether the chosen level is genuinely audible from your pillow. The ferry pickup may be missed if this page is closed or your phone is allowed to sleep, because the browser alarm cannot then sound; keep it active and use a separate alarm as backup if punctuality is critical.
On the way to Liverpool’s ferry terminal, the surroundings may shift from a nearly silent street to louder main roads, ventilation systems and idling vehicles. Keep your keys and clothes away from humming appliances so you can hear any backup signal, and allow a few seconds after waking before switching it off. At 2:27 am, a bright screen can also feel harsh, so lower the display beforehand while leaving the alarm volume unchanged.
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.
