Online alarm clock for 12:25 am
Waiting for night check-in to open for an eastbound flight across Australia can make 12:25 am feel unusually slow. Set the alarm for the appointed moment, then use the 35 minutes before 1:00 am to check passenger details, place your passport or ID beside your bag, and keep the booking reference handy.
Your surroundings should decide how 12:25 am sounds. A gentle tone may be enough if you are watching the clock with your phone nearby, while a more persistent sound suits anyone likely to drift off before registration begins. Check the volume now and avoid audio that blends into music or background noise. Do not rely on this as the sole flight check-in alert: if the browser session ends or the phone goes to sleep, the time can pass without a sound.
While you wait for the overnight registration window, consider who else in the house will hear the alarm. Keep the phone close to your seat and start with moderate volume rather than leaving it across the room at full strength. Vibration on a firm bedside table can carry through a quiet home, so place it on a folded cloth if someone is sleeping nearby. When 12:25 am arrives, silence it promptly before opening the airline details you prepared.
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.
