How to use the online alarm clock
If the evening is when you get things done — an assignment, a load of washing, dinner prep — 8:13 pm is a sensible time to set a firm reminder. This tool rings at 8:13 pm through your laptop or desktop speakers, whether the tab's open on the kitchen bench or the desk.
Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.
Because this runs in the browser rather than on the phone's operating system, it sidesteps silent mode and do-not-disturb entirely, useful if your phone alarm has ever failed to go off for exactly that reason. Just be aware it needs the tab open and the screen or laptop lid to stay on to actually ring. On a 24-hour clock 8:13 pm is written 20:13, and spoken aloud it's thirteen minutes past eight in the evening. You'll also see it written 8.13 pm — a full stop instead of the colon means the same time. Setting the alarm to 8:13 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.
