How to use the online alarm clock

An evening alarm at 8:33 pm is usually about getting dinner started, leaving for a night class, or reminding the kids it's nearly bedtime. Set it once, pick a sound that won't be lost in the evening noise, and this page will ring at 8:33 pm through your speakers.

Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.

This works well as a second alarm, one that isn't tangled up with phone notifications, do-not-disturb settings, or low battery. It genuinely won't ring if the tab gets closed or the device goes to sleep, so treat it as a backup or a work-desk tool rather than the only alarm for something important. On a 24-hour clock 8:33 pm is written 20:33, and spoken aloud it's twenty-seven minutes to nine at night. Written the Australian way that's 8.33 pm, and typed in a hurry it's often 8:33pm. Setting the alarm to 8:33 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

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.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
