How to use the online alarm clock
An evening alarm at 8:47 pm is usually about getting dinner started, leaving for a night class, or reminding the kids it's nearly bedtime. Set it once, pick a sound that won't be lost in the evening noise, and this page will ring at 8:47 pm through your speakers.
Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.
Because this runs in the browser rather than on the phone's operating system, it sidesteps silent mode and do-not-disturb entirely, useful if your phone alarm has ever failed to go off for exactly that reason. Just be aware it needs the tab open and the screen or laptop lid to stay on to actually ring. On a 24-hour clock 8:47 pm is written 20:47, and spoken aloud it's thirteen minutes to nine at night. Written the Australian way that's 8.47 pm, and typed in a hurry it's often 8:47pm. Setting the alarm to 8:47 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
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.
