How to use the online alarm clock
Setting an alarm for 3:00 pm in the afternoon is often about leaving enough time to beat the traffic home, or to get to training before it starts. This page rings at 3:00 pm through your speakers. No sign-up, no app, just a tab left open.
Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.
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 3:00 pm is written 15:00, and spoken aloud it's three o'clock in the afternoon. You'll also see it written 3.00 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 3:00 pm or put an alarm on for 3:00 pm, the steps are the same: pick a sound, press Start, leave the tab open.
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.
