Going to bed for a 4:22 am alarm

Asleep by 7:07 pm — 6 full sleep cycles, about 9 hours
Asleep by 8:37 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:07 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.

Online alarm clock for 4:22 am

Getting ready at 4:22 am for an online game with European players means sorting out the alarm before the match absorbs your attention. Setting it now leaves the next 38 minutes free for checking your headset, joining the lobby and settling in before 5:00 am. The alarm provides a clear marker for whatever needs to happen at that round hour.

Because the match may involve switching windows or using full-screen mode, the browser needs a little care. After selecting 5:00 am, the alarm page should remain open and the computer or phone should stay awake with its sound audible. Closing the page or browser, or letting the device sleep, means the alarm cannot interrupt the online game when the chosen time arrives. A quick sound check beforehand confirms that the volume is suitable without relying on a last-minute adjustment.

During an overnight gaming session in Australia, household and street noise will usually be much lower than it is during the day, yet it may begin changing as 5:00 am approaches. Keep the alarm loud enough to stand out from game audio, but consider anyone sleeping nearby; headphones can carry the game while a moderate speaker alert marks the time. Early traffic, birds or an air conditioner may otherwise mask a quiet tone.

Common questions

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.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
