The Moon does not revolve around the Earth

At least, not in the manner that you might have been told that it does. Even the orbit diagram posted earlier doesn't show the real deal... but it is, of course, only two-dimensional.



The Moon and Earth revolve around a common center of gravity. The image above came from the 13 Moon Calendar website, that calendar having been derived from Mayan (and other cultures') time systems that were based on the 13, 28-day lunations that take place each year.

13 x 28 = 364, by the way. The 365th day (July 26, I think) is considered "a day out of time;" a new year's day, during which festivals and ceremonies were (and are now) held. This is the day of Sirius' heliacal rising -- the day it rises above the horizon with the Sun.
