How to use the online alarm clock

The arvo slump hits hard after lunch, and an alarm for 5:31 pm is often just a way to stop a short break turning into an hour. Set it, pick a sound, and this page will ring at 5:31 pm through your speakers to get you back on track.

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.

Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 5:31 pm is written 17:31, and spoken aloud it's twenty-nine minutes to six in the evening. Written the Australian way that's 5.31 pm, and typed in a hurry it's often 5:31pm. Whether you would say set alarm for 5:31 pm or put an alarm on for 5:31 pm, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

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.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

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.
