Online alarm clock for 12:21 pm
As you finish checking the Bureau of Meteorology UV index and head off, an alarm for 12:21 pm can mark the moment to stop reading the forecast and get moving. It also leaves a clear boundary before 1:00 pm, so the midday check does not drift into whatever you have planned for the afternoon.
Because you are leaving as soon as the alarm sounds, keep the browser running and prevent your phone from sleeping beforehand. If either stops the browser alarm, the UV index check may run past 12:21 pm without an audible warning. Set the volume to a level you can hear, then test the sound if you are relying on it while packing up or moving away from the screen.
Heading outside at midday can mean a sharp change from a dim room to strong Australian daylight. Before 12:21 pm, place sunglasses, a hat, or anything else you intend to take where the light makes it easy to spot. Keeping the screen out of direct glare also makes the final Bureau reading easier to see, while a shaded position prevents reflections from slowing you down just as you are ready to leave.
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.
