How to use the online alarm clock
An evening alarm at 8:27 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 8:27 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.
Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 8:27 pm is written 20:27, and spoken aloud it's twenty-seven minutes past eight in the evening. You'll also see it written 8.27 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 8:27 pm or put an alarm on for 8:27 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.
