Online alarm clock for 12:48 am

You’re finishing the last checks and heading off so the long drive through the bush can begin before kangaroos gather near the roadside. A 12:48 am alarm gives you a clear departure cue, with 1:00 am close enough to serve as the final checkpoint for keys, water and fuel. That keeps the late-night pack-up from quietly stretching into lost driving time.

For a bush run that depends on one precise wake-up, the alarm sound needs proving before you rely on it. Set the time, start the alarm, then play a brief test at the same volume and through the same speaker you expect to use. If this page is closed or your phone or laptop falls asleep, no sound will play, leaving the bush drive without its planned wake-up. A separate phone alarm is sensible backup for this departure.

A pre-dawn bush departure can disturb the whole house long before anyone else needs to be awake. Put your gear and car keys near the exit earlier, avoid rattling cupboards after the 12:48 am signal, and choose an alarm loud enough for you without carrying into nearby bedrooms. Vibrate can add a private cue if the phone stays beside you, while shoes by the door help you leave quietly once the alarm sounds.

Common questions

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

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.
