How to use the online alarm clock
School pickup, footy training, or just leaving work on time: 3:48 pm in the afternoon is a common deadline people don't want to miss. This rings straight from your browser at 3:48 pm, and keeps going until you stop it. No phone required nearby.
Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.
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 3:48 pm is written 15:48, and spoken aloud it's twelve minutes to four in the afternoon. Timetables and rosters may show it as 15:48, and handwritten notes as 3.48 pm. Setting the alarm to 3:48 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
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.
