How to use the online alarm clock
Late-night study or a last email before bed can run past 11:34 pm without anyone noticing, which is exactly what this alarm is for. Set it here and it'll ring at 11:34 pm through your speakers, a firm enough nudge to actually close the laptop.
Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.
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 11:34 pm is written 23:34, and spoken aloud it's twenty-six minutes to twelve at night. You'll also see it written 11.34 pm — a full stop instead of the colon means the same time. Set an alarm for 11:34 pm, set the alarm to 11:34 pm, set my alarm for 11:34 pm — all of it lands on this page and does the same thing.
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.
