How to use the online alarm clock
Setting an alarm for 11:36 pm at night often comes down to one thing: not trusting yourself to notice the time once you're deep into something else, whether that's study, a show, or work that's run late. This will ring at 11:36 pm through your device's speakers until you stop it.
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.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 11:36 pm is written 23:36, and spoken aloud it's twenty-four minutes to twelve at night. You'll also see it written 11.36 pm — a full stop instead of the colon means the same time. Set an alarm for 11:36 pm, set the alarm to 11:36 pm, set my alarm for 11:36 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.
