How to use the online alarm clock
An alarm for 12:29 am is usually about catching something before the rest of the world is awake: a ferry, a flight, or a change of shift. Set the time, pick a tone, and leave this tab open. At 12:29 am it'll ring through your device's speakers until you tell it to stop.
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.
The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 12:29 am is written 00:29, and spoken aloud it's twenty-nine minutes past twelve at night. Written the Australian way that's 12.29 am, and typed in a hurry it's often 12:29am. Setting the alarm to 12:29 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
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.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
