How to use the online alarm clock
As you finish what you are doing and head out to meet the ferry from Belfast in Liverpool, set the alarm for 1:06 am so departure does not slip amid last-minute checks. The ring comes well before 2:00 am, leaving time to collect your keys, check the arrival information and reach the terminal without treating the round hour as your actual deadline.
Once your ferry alarm is set, keep this page in the foreground when practical; browsers can reduce activity on a page left behind another app or screen, which may affect its timing or sound. Check that the volume is audible before switching away. If you close the page or let the computer or phone go to sleep, the ferry reminder will not sound, so use a separate alarm if you plan to leave it unattended.
Leaving for the Liverpool terminal at 1:06 am can mean stepping from a warm room into a cool, damp night. A heavily heated cabin may make the change feel sharper, while strong air conditioning can leave the car uncomfortably cold before the journey begins. Set a moderate temperature, keep a light layer within reach and clear any mist from the windows before pulling away.
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.
