How to use the online alarm clock
Setting an alarm for 12:33 am while everyone else is asleep can feel like cheating the clock, but it's usually just planning ahead for an early departure or a shift that starts before sunrise. This will sound at 12:33 am through your speakers, whether it's the depths of winter or a short summer night.
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 12:33 am is written 00:33, and spoken aloud it's twenty-seven minutes to one at night. Timetables and rosters may show it as 00:33, and handwritten notes as 12.33 am. Set an alarm for 12:33 am, set the alarm to 12:33 am, set my alarm for 12:33 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.
