How to use the online alarm clock
If you're still up rather than getting up, setting this for 12:56 am gives you a hard stop. Daylight saving time or not, the sun won't be up yet. It works the same regardless of the season, ringing at 12:56 am sharp through your speakers, so you can finally close the laptop and get some sleep.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
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 12:56 am is written 00:56, and spoken aloud it's four minutes to one at night. Timetables and rosters may show it as 00:56, and handwritten notes as 12.56 am. Whether you would say set alarm for 12:56 am or put an alarm on for 12:56 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
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.
