How to use the online alarm clock
Tradies, nurses on night shift, and anyone driving to the airport before the birds wake up all end up here around 3:28 am. This alarm rings straight from your browser tab at 3:28 am, loud enough to cut through a quiet house, without needing an app or an account first.
After picking a tone, press Start and leave the page open. It doesn't need an internet connection once it's running, but it does need the tab itself to stay open, so avoid closing the browser or letting the device fall asleep before the time is reached.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 3:28 am is written 03:28, and spoken aloud it's twenty-eight minutes past three at night. You'll also see it written 3.28 am — a full stop instead of the colon means the same time. Setting the alarm to 3:28 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.
