How to use the online alarm clock
A midday alarm at 12:09 pm is usually about not losing track of lunch, a call, or the end of a break. Set it once, leave the tab open on your work computer, and it'll ring at 12:09 pm even if you've gotten lost in something else entirely.
After picking a tone, press Start and leave the page open. It doesn't need an internet connection once it's running, but it does need the tab itself to stay open, so avoid closing the browser or letting the device fall asleep before the time is reached.
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 12:09 pm is written 12:09, and spoken aloud it's nine minutes past twelve in the afternoon. Timetables and rosters may show it as 12:09, and handwritten notes as 12.09 pm. Set an alarm for 12:09 pm, set the alarm to 12:09 pm, set my alarm for 12:09 pm — all of it lands on this page and does the same thing.
Common questions
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
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.
