How to use the online alarm clock
Nobody sets an alarm for 12:41 am for fun. Maybe it's an early shift at the depot, a long drive before the roads get busy, or you're still awake and don't trust yourself to notice the time. Pick a sound, set it for 12:41 am, and this page will handle the rest while the house stays quiet.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
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 12:41 am is written 00:41, and spoken aloud it's nineteen minutes to one at night. Written the Australian way that's 12.41 am, and typed in a hurry it's often 12:41am. Setting the alarm to 12:41 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
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.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
