Going to bed for a 10:52 am alarm

Asleep by 1:37 am — 6 full sleep cycles, about 9 hours
Asleep by 3:07 am — 5 full sleep cycles, about 7 hours
Asleep by 4:37 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

Mornings between six and eleven are when most households actually need an alarm, not the phone buried in a bag by the door. Set this one for 10:52 am, pick something loud enough to cut through breakfast noise, and it'll ring right on 10:52 am through your laptop or desktop speakers.

There's a short list of sounds to choose from before you press Start — pick one that suits how deep a sleeper you are. Once it's set, the page keeps time in the background of your browser, and it'll sound at the moment you selected, provided the tab hasn't been closed.

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 10:52 am is written 10:52, and spoken aloud it's eight minutes to eleven in the morning. Timetables and rosters may show it as 10:52, and handwritten notes as 10.52 am. Whether you would say set alarm for 10:52 am or put an alarm on for 10:52 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.
