Going to bed for a 11:54 am alarm

Asleep by 2:39 am — 6 full sleep cycles, about 9 hours
Asleep by 4:09 am — 5 full sleep cycles, about 7 hours
Asleep by 5:39 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

Between video calls and a late lunch, it's easy to lose track of the clock, which is why 11:54 am shows up so often as a midday alarm. This rings straight from your browser at 11:54 am. No app, no account, just a tab that needs to stay open.

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.

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 11:54 am is written 11:54, and spoken aloud it's six minutes to twelve in the afternoon. You'll also see it written 11.54 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 11:54 am or put an alarm on for 11:54 am, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

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.

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.
