How to use the online alarm clock
Setting an alarm for 11:56 am in the middle of the day sounds unnecessary until you've missed a lunch meeting because you were heads-down in something else. This rings through your browser at 11:56 am, loud enough to notice at a desk, without needing your phone within reach.
Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 11:56 am is written 11:56, and spoken aloud it's four minutes to twelve in the afternoon. Written the Australian way that's 11.56 am, and typed in a hurry it's often 11:56am. Set an alarm for 11:56 am, set the alarm to 11:56 am, set my alarm for 11:56 am — 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.
