How to use the online alarm clock
Three in the morning has its own kind of silence, and an alarm for 3:19 am breaks it on purpose. Whether you're catching a pre-dawn flight or grabbing a short nap before a long haul, this tool rings at 3:19 am through your browser so you're not relying on a phone across the room.
Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.
Compared to a phone, this alarm has one job and nothing else competing for attention — no messages, no app switching. It's free and doesn't ask for sign-up, but it only works while the tab is open and the device stays awake, so it suits daytime use at a desk better than an overnight bedroom alarm. On a 24-hour clock 3:19 am is written 03:19, and spoken aloud it's nineteen minutes past three at night. You'll also see it written 3.19 am — a full stop instead of the colon means the same time. Set an alarm for 3:19 am, set the alarm to 3:19 am, set my alarm for 3:19 am — all of it lands on this page and does the same thing.
Common questions
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.
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.
