How to use the online alarm clock
The arvo slump hits hard after lunch, and an alarm for 3:24 pm is often just a way to stop a short break turning into an hour. Set it, pick a sound, and this page will ring at 3:24 pm through your speakers to get you back on track.
Pick whichever sound you're most likely to actually notice, then press Start. The alarm is tied to this browser tab, so it needs to stay open. Minimising the window is fine, but closing the tab or the browser will stop the countdown before it ever rings.
It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 3:24 pm is written 15:24, and spoken aloud it's twenty-four minutes past three in the afternoon. Timetables and rosters may show it as 15:24, and handwritten notes as 3.24 pm. Set an alarm for 3:24 pm, set the alarm to 3:24 pm, set my alarm for 3:24 pm — all of it lands on this page and does the same thing.
Common questions
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.
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.
