Online alarm clock for 4:20 pm
Finish what you’re doing and leave when the 4:20 pm alarm sounds, so you have a clear cue to meet the ferry from Kangaroo Island. That gives the trip its own firm departure point instead of letting one last job delay you. With 5:00 pm approaching, you can use the remaining time for the drive, parking and finding the right meeting spot.
A ferry arrival can be easy to miss when conversation, traffic or music is louder than your phone. Set the alarm volume high enough to stand out from the background, then play a quick test before you put the phone away. Keep it close rather than buried in a bag or left across the room. Your ferry pickup cannot rely on this browser alarm if you close the page or allow the phone to sleep, because the signal may not sound.
Heading out in the late afternoon can put low sun or bright reflections across your screen just when you need to check the time. Increase the display brightness only enough to read 4:20 pm clearly, enlarge the on-screen time if that helps, and stand in shade while checking it. Once the alarm is set, lock in the meeting details and avoid repeatedly looking at the display during the journey.
Common questions
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
