How to use the online alarm clock
A quick nap over lunch only works if something reliably wakes you up again, and 1:13 pm is a common target for exactly that. Set the time, pick a tone, and this tool will ring at 1:13 pm through your speakers so the rest of your day isn't wrecked.
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.
Because this runs in the browser rather than on the phone's operating system, it sidesteps silent mode and do-not-disturb entirely, useful if your phone alarm has ever failed to go off for exactly that reason. Just be aware it needs the tab open and the screen or laptop lid to stay on to actually ring. On a 24-hour clock 1:13 pm is written 13:13, and spoken aloud it's thirteen minutes past one in the afternoon. You'll also see it written 1.13 pm — a full stop instead of the colon means the same time. Set an alarm for 1:13 pm, set the alarm to 1:13 pm, set my alarm for 1:13 pm — all of it lands on this page and does the same thing.
Common questions
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.
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.
