How to use the online alarm clock
Between video calls and a late lunch, it's easy to lose track of the clock, which is why 12:25 pm shows up so often as a midday alarm. This rings straight from your browser at 12:25 pm. No app, no account, just a tab that needs to stay open.
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 12:25 pm is written 12:25, and spoken aloud it's twenty-five past twelve in the afternoon. You'll also see it written 12.25 pm — a full stop instead of the colon means the same time. Set an alarm for 12:25 pm, set the alarm to 12:25 pm, set my alarm for 12:25 pm — all of it lands on this page and does the same thing.
Common questions
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.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
