How to use the online alarm clock
Finish what you are doing and head out to meet the Belfast ferry in Liverpool when the alarm sounds at 1:54 am. That leaves a short margin before 2:00 am for picking up your keys, checking the arrival point and getting to the terminal without turning the final minutes into a rush.
Before leaving, check where the alarm sound will actually play. A phone may quietly route it to paired headphones left in a coat pocket or on a bedside table, making the alert easy to miss. Disconnect them or choose the phone speaker, then confirm the volume is audible. Keep the browser running and the phone awake as well: otherwise the alarm may remain silent and the ferry collection could be delayed.
After the Liverpool pick-up, protect whatever sleep is still available by keeping the return routine brief. Leave night clothes and a glass of water ready before setting off, and keep bright lights low when you come back. At this hour, deciding those small details beforehand makes it easier to go straight to bed instead of becoming occupied with jobs that can wait until morning.
Common questions
What happens if my laptop goes to sleep before 1:54 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
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.
