How to use the online alarm clock
Setting an alarm for 3:25 pm in the afternoon is often about leaving enough time to beat the traffic home, or to get to training before it starts. This page rings at 3:25 pm through your speakers. No sign-up, no app, just a tab left open.
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 3:25 pm is written 15:25, and spoken aloud it's twenty-five past three in the afternoon. You'll also see it written 3.25 pm — a full stop instead of the colon means the same time. Set an alarm for 3:25 pm, set the alarm to 3:25 pm, set my alarm for 3:25 pm — all of it lands on this page and does the same thing.
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.
