Going to bed for a 3:06 am alarm

Asleep by 5:51 pm — 6 full sleep cycles, about 9 hours
Asleep by 7:21 pm — 5 full sleep cycles, about 7 hours
Asleep by 8:51 pm — 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

Newborns don't care what time it is, and neither does an early shift roster. If 3:06 am is when you need to be up and moving, this page will ring at exactly 3:06 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.

Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.

Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 3:06 am is written 03:06, and spoken aloud it's six minutes past three at night. Written the Australian way that's 3.06 am, and typed in a hurry it's often 3:06am. Whether you would say set alarm for 3:06 am or put an alarm on for 3:06 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.
