How to use the online alarm clock
Between video calls and a late lunch, it's easy to lose track of the clock, which is why 11:33 am shows up so often as a midday alarm. This rings straight from your browser at 11:33 am. No app, no account, just a tab that needs to stay 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.
Compared to a phone, this alarm has one job and nothing else competing for attention — no messages, no app switching. It's free and doesn't ask for sign-up, but it only works while the tab is open and the device stays awake, so it suits daytime use at a desk better than an overnight bedroom alarm. On a 24-hour clock 11:33 am is written 11:33, and spoken aloud it's twenty-seven minutes to twelve in the afternoon. You'll also see it written 11.33 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 11:33 am or put an alarm on for 11:33 am, 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.
