How to use the online alarm clock
Tradies, nurses on night shift, and anyone driving to the airport before the birds wake up all end up here around 1:47 am. This alarm rings straight from your browser tab at 1:47 am, loud enough to cut through a quiet house, without needing an app or an account first.
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.
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 1:47 am is written 01:47, and spoken aloud it's thirteen minutes to two at night. You'll also see it written 1.47 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 1:47 am or put an alarm on for 1:47 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
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.
