Going to bed for a 11:12 am alarm

Asleep by 1:57 am — 6 full sleep cycles, about 9 hours
Asleep by 3:27 am — 5 full sleep cycles, about 7 hours
Asleep by 4:57 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

Whether it's a reminder to leave for an appointment or the end of a lunch break that's gone on too long, 11:12 am works as a firm nudge in the middle of the day. Set it here and it'll ring at 11:12 am through your device's speakers until dismissed.

Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.

It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 11:12 am is written 11:12, and spoken aloud it's twelve minutes past eleven in the morning. You'll also see it written 11.12 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 11:12 am or put an alarm on for 11:12 am, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
