How to use the online alarm clock
Setting an alarm for 12:17 pm in the middle of the day sounds unnecessary until you've missed a lunch meeting because you were heads-down in something else. This rings through your browser at 12:17 pm, loud enough to notice at a desk, without needing your phone within reach.
There's a short list of sounds to choose from before you press Start — pick one that suits how deep a sleeper you are. Once it's set, the page keeps time in the background of your browser, and it'll sound at the moment you selected, provided the tab hasn't been closed.
The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 12:17 pm is written 12:17, and spoken aloud it's seventeen minutes past twelve in the afternoon. You'll also see it written 12.17 pm — a full stop instead of the colon means the same time. If you need it loud, turn the system volume up before you start: the alarm plays at whatever the device is set to.
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.
