Online alarm clock for 2:23 am
As you hand the overnight check-in watch to someone else, set the 2:23 am alarm so the eastbound flight across Australia stays on track after the changeover. It gives the next person a clear cue to check the airline details, documents and bags before 3:00 am, without relying on a sleepy verbal reminder.
Your flight handover can quietly fail if the alarm sound has been routed to headphones left plugged in or connected by Bluetooth. Before stepping away, play a short test and confirm that the sound comes from a speaker the other person will hear. Set a sensible volume, then leave the browser running. If the browser is closed or the computer goes to sleep, the flight check-in alarm will not sound, so use a separate phone alarm when missing it could disrupt the trip.
Because 2:23 am falls deep in the night, keep the changeover brief and considerate of everyone else in the house. Put the speaker near the person taking responsibility rather than turning it up across several rooms, and close nearby doors if that will contain the noise. Have passports, booking information and luggage together beforehand, so the alarm prompts one quiet check instead of lights, cupboards and conversation waking the household.
Common questions
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
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.
