How to use the online alarm clock
Newborns don't care what time it is, and neither does an early shift roster. If 3:11 am is when you need to be up and moving, this page will ring at exactly 3:11 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
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 3:11 am is written 03:11, and spoken aloud it's eleven minutes past three at night. Timetables and rosters may show it as 03:11, and handwritten notes as 3.11 am. Setting the alarm to 3:11 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
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.
