How to use the online alarm clock

Getting the kids into a bedtime routine often comes down to one reliable alarm at 7:43 pm that isn't ignored the way a phone reminder gets swiped away. Set it here and it'll ring at 7:43 pm through your speakers until someone turns it off.

Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.

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 7:43 pm is written 19:43, and spoken aloud it's seventeen minutes to eight in the evening. Written the Australian way that's 7.43 pm, and typed in a hurry it's often 7:43pm. Setting the alarm to 7:43 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

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.

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.
