How to use the online alarm clock
If the afternoon has you juggling pickups, training runs, or a second job starting later, 5:43 pm is worth setting properly rather than trusting memory. This tool rings at 5:43 pm straight from your browser, loud enough to notice over the usual afternoon noise at home.
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 5:43 pm is written 17:43, and spoken aloud it's seventeen minutes to six in the evening. Written the Australian way that's 5.43 pm, and typed in a hurry it's often 5:43pm. Whether you would say set alarm for 5:43 pm or put an alarm on for 5:43 pm, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
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.
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.
