How to use the online alarm clock
Night owls and shift workers both end up setting alarms around 11:56 pm, just for different reasons — one to stop, one to start. Pick a sound, set it for 11:56 pm, and this page will ring through your browser for as long as the tab's 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 11:56 pm is written 23:56, and spoken aloud it's four minutes to twelve at night. Timetables and rosters may show it as 23:56, and handwritten notes as 11.56 pm. Whether you would say set alarm for 11:56 pm or put an alarm on for 11:56 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.
