Online alarm clock for 1:12 pm

Break away from what you are doing at 1:12 pm to check whether the car has become too hot in the Australian sun. The alarm marks a deliberate interruption rather than leaving you to remember while concentrating on something else. It also gives you time to inspect the cabin, open the doors safely and deal with the heat before 2:00 pm.

Because the car check matters, test the alarm sound before relying on it: a short trial confirms that the selected tone is audible at your current volume. Once that check works, set 1:12 pm and leave the browser available while you return to your task. If the tab is closed or the device goes to sleep, no alarm will sound, so the car could remain heating in the sun longer than you intended.

If this midday reminder interrupts sleep after a night shift or an early start, keep the interruption contained. Place your keys, shoes and a bottle of water together before lying down, so checking the car does not turn into a long search around the house. After 1:12 pm, dim the room again and silence unrelated notifications; that preserves more of the sleep still available once the inspection is finished.

Common questions

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.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

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.
