Online alarm clock for 11:47 pm

You are halfway through something else when the 11:47 pm alarm pulls you away to close the shutters before a windy night. That leaves enough time to secure each one properly before 12:00 am, rather than rushing outside at midnight when the gusts may already be rattling them.

Match the alarm sound to how easily you might miss it while occupied. A gentle tone suits a quiet room when the phone is nearby, while a persistent sound makes more sense if wind noise or a running television could mask the first alert. Keep the volume audible from where you are working. The shutters will get no reminder if the browser alarm has stopped running before 11:47 pm, so use a separate phone alarm when closing them cannot be missed.

Late-evening noise carries through an Australian home, especially once everyone else has settled down. Place the phone close enough that a softer alert can catch your attention without waking housemates or children. When the alarm sounds, silence it before heading around the windows, then use a torch outside instead of switching on bright lights near bedrooms. Check latches firmly but quietly, and avoid letting loose shutter panels knock against the wall in the wind.

Common questions

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.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
