Going to bed for a 6:45 am alarm

Asleep by 9:30 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:00 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:30 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 6:45 am, pick something loud enough to cut through breakfast noise, and it'll ring right on 6:45 am through your laptop or desktop speakers.

After picking a tone, press Start and leave the page open. It doesn't need an internet connection once it's running, but it does need the tab itself to stay open, so avoid closing the browser or letting the device fall asleep before the time is reached.

The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 6:45 am is written 06:45, and spoken aloud it's quarter to seven in the morning. Written the Australian way that's 6.45 am, and typed in a hurry it's often 6:45am. Whether you would say set alarm for 6:45 am or put an alarm on for 6:45 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.
