How to use the online alarm clock
An afternoon alarm at 2:38 pm works well for anyone who's ducked away for a quick rest and doesn't trust themselves to wake up on their own. Set the time, choose a tone, and leave the tab open. It'll ring at 2:38 pm through your laptop or desktop speakers.
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.
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 2:38 pm is written 14:38, and spoken aloud it's twenty-two minutes to three in the afternoon. You'll also see it written 2.38 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 2:38 pm or put an alarm on for 2:38 pm, the steps are the same: pick a sound, press Start, leave the tab open.
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.
