How to use the online alarm clock
Setting an alarm for 10:24 pm at night often comes down to one thing: not trusting yourself to notice the time once you're deep into something else, whether that's study, a show, or work that's run late. This will ring at 10:24 pm through your device's speakers until you stop it.
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 10:24 pm is written 22:24, and spoken aloud it's twenty-four minutes past ten at night. You'll also see it written 10.24 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 10:24 pm or put an alarm on for 10:24 pm, 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.
