How to use the online alarm clock

Newborns don't care what time it is, and neither does an early shift roster. If 12:02 am is when you need to be up and moving, this page will ring at exactly 12:02 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.

Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.

This works well as a second alarm, one that isn't tangled up with phone notifications, do-not-disturb settings, or low battery. It genuinely won't ring if the tab gets closed or the device goes to sleep, so treat it as a backup or a work-desk tool rather than the only alarm for something important. On a 24-hour clock 12:02 am is written 00:02, and spoken aloud it's two minutes past twelve at night. Written the Australian way that's 12.02 am, and typed in a hurry it's often 12:02am. If you need it loud, turn the system volume up before you start: the alarm plays at whatever the device is set to.

Common questions

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.

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.
