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.

Online alarm clock for 3:06 am

Preparing early for a domestic flight north, you can set the alarm for 3:06 am while checking your bags, identification and trip to the airport. That gives you a clear point to stop preparing and start the next part of the journey, well before 4:00 am arrives. Keep the phone nearby so the alarm is easy to hear.

Your early departure depends on the browser remaining active until the chosen time. A phone that goes to sleep beforehand may prevent the sound from playing, so this browser alarm cannot safeguard your flight after the page is closed or the phone becomes inactive. Leave the page open, keep the phone awake and connected to power, and set a separate system alarm as a fallback for the airport run.

Because the trip begins during the night, allow a buffer between 3:06 am and the next task rather than assigning every minute. Place keys, luggage and travel documents together before resting, then use the alarm as the signal to get moving. A little spare time can absorb a slow rideshare pickup, a missed turn on quiet streets or a longer bag drop without pushing the rest of the morning off schedule.

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.
