How to use the online alarm clock

Newborns don't care what time it is, and neither does an early shift roster. If 2:13 am is when you need to be up and moving, this page will ring at exactly 2:13 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.

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.

The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 2:13 am is written 02:13, and spoken aloud it's thirteen minutes past two at night. Timetables and rosters may show it as 02:13, and handwritten notes as 2.13 am. Whether you would say set alarm for 2:13 am or put an alarm on for 2:13 am, the steps are the same: pick a sound, press Start, leave the tab open.

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.
