How to use the online alarm clock
Night owls and shift workers both end up setting alarms around 10:02 pm, just for different reasons — one to stop, one to start. Pick a sound, set it for 10:02 pm, and this page will ring through your browser for as long as the tab's open.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 10:02 pm is written 22:02, and spoken aloud it's two minutes past ten at night. Timetables and rosters may show it as 22:02, and handwritten notes as 10.02 pm. Set an alarm for 10:02 pm, set the alarm to 10:02 pm, set my alarm for 10:02 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.
