How to use the online alarm clock
If daylight's still up but the day's winding down, 3:17 pm can mark the point where afternoon chores need to stop and the evening routine needs to start. Set it here, choose a sound, and it'll ring at 3:17 pm until dismissed.
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.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 3:17 pm is written 15:17, and spoken aloud it's seventeen minutes past three in the afternoon. You'll also see it written 3.17 pm — a full stop instead of the colon means the same time. Set an alarm for 3:17 pm, set the alarm to 3:17 pm, set my alarm for 3:17 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.
