How to use the online alarm clock
Night owls and shift workers both end up setting alarms around 11:45 pm, just for different reasons — one to stop, one to start. Pick a sound, set it for 11:45 pm, and this page will ring through your browser for as long as the tab's open.
Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.
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 11:45 pm is written 23:45, and spoken aloud it's quarter to twelve at night. Written the Australian way that's 11.45 pm, and typed in a hurry it's often 11:45pm. Whether you would say set alarm for 11:45 pm or put an alarm on for 11:45 pm, the steps are the same: pick a sound, press Start, leave the tab open.
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.
