How to use the online alarm clock
A midday alarm at 12:49 pm is usually about not losing track of lunch, a call, or the end of a break. Set it once, leave the tab open on your work computer, and it'll ring at 12:49 pm even if you've gotten lost in something else entirely.
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.
A browser alarm like this one is handy when your phone's on silent, charging in another room, or you just don't want to unlock it and get pulled into notifications. The trade-off is honesty: it only rings while this tab stays open, so it's not a replacement for your phone alarm on a trip where the laptop lid might close. On a 24-hour clock 12:49 pm is written 12:49, and spoken aloud it's eleven minutes to one in the afternoon. You'll also see it written 12.49 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 12:49 pm or put an alarm on for 12:49 pm, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
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.
