How to use the online alarm clock
An evening alarm at 6:20 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 6:20 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.
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 6:20 pm is written 18:20, and spoken aloud it's twenty past six in the evening. Written the Australian way that's 6.20 pm, and typed in a hurry it's often 6:20pm. Set an alarm for 6:20 pm, set the alarm to 6:20 pm, set my alarm for 6:20 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.
