How to use the online alarm clock
An afternoon alarm at 3:01 pm works well for anyone who's ducked away for a quick rest and doesn't trust themselves to wake up on their own. Set the time, choose a tone, and leave the tab open. It'll ring at 3:01 pm through your laptop or desktop speakers.
Pick whichever sound you're most likely to actually notice, then press Start. The alarm is tied to this browser tab, so it needs to stay open. Minimising the window is fine, but closing the tab or the browser will stop the countdown before it ever rings.
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 3:01 pm is written 15:01, and spoken aloud it's one minutes past three in the afternoon. Timetables and rosters may show it as 15:01, and handwritten notes as 3.01 pm. Whether you would say set alarm for 3:01 pm or put an alarm on for 3:01 pm, 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.
