How to use the online alarm clock
Newborns don't care what time it is, and neither does an early shift roster. If 1:43 am is when you need to be up and moving, this page will ring at exactly 1:43 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.
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.
It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 1:43 am is written 01:43, and spoken aloud it's seventeen minutes to two at night. Timetables and rosters may show it as 01:43, and handwritten notes as 1.43 am. Setting the alarm to 1:43 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
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.
