Going to bed for a 7:20 am alarm

Asleep by 10:05 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:35 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:05 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

If the school run is tight, an alarm at 7:20 am buys you the minutes you actually need to get everyone dressed, fed, and out the door. Set the time, choose a tone that won't get ignored, and this page will ring at 7:20 am through your speakers for as long as you let it.

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.

Because this runs in the browser rather than on the phone's operating system, it sidesteps silent mode and do-not-disturb entirely, useful if your phone alarm has ever failed to go off for exactly that reason. Just be aware it needs the tab open and the screen or laptop lid to stay on to actually ring. On a 24-hour clock 7:20 am is written 07:20, and spoken aloud it's twenty past seven in the morning. You'll also see it written 7.20 am — a full stop instead of the colon means the same time. Set an alarm for 7:20 am, set the alarm to 7:20 am, set my alarm for 7:20 am — all of it lands on this page and does the same thing.

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.
