How to use the online alarm clock

A quick nap over lunch only works if something reliably wakes you up again, and 12:29 pm is a common target for exactly that. Set the time, pick a tone, and this tool will ring at 12:29 pm through your speakers so the rest of your day isn't wrecked.

Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.

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 12:29 pm is written 12:29, and spoken aloud it's twenty-nine minutes past twelve in the afternoon. Timetables and rosters may show it as 12:29, and handwritten notes as 12.29 pm. Whether you would say set alarm for 12:29 pm or put an alarm on for 12:29 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.
