How to use the online alarm clock
If the afternoon has you juggling pickups, training runs, or a second job starting later, 4:25 pm is worth setting properly rather than trusting memory. This tool rings at 4:25 pm straight from your browser, loud enough to notice over the usual afternoon noise at home.
There's a short list of sounds to choose from before you press Start — pick one that suits how deep a sleeper you are. Once it's set, the page keeps time in the background of your browser, and it'll sound at the moment you selected, provided the tab hasn't been closed.
Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 4:25 pm is written 16:25, and spoken aloud it's twenty-five past four in the afternoon. Timetables and rosters may show it as 16:25, and handwritten notes as 4.25 pm. Set an alarm for 4:25 pm, set the alarm to 4:25 pm, set my alarm for 4:25 pm — all of it lands on this page and does the same thing.
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.
