The moon shows its full face to Earth once a month. Well, sort of.
In fact, the same side of the moon always faces the planet, but part of it is in shadow. And, in reality most of the time the "full moon" is never perfectly full. Only when the moon, Earth and the sun are perfectly aligned is the moon 100 percent full, and that alignment produces a lunar eclipse. And sometimes — once in a blue moon — the moon is full twice in a month (or four times in a season, depending on which definition you prefer). [The Moon: 10 Surprising Facts]

The full moon of November will occur on Friday, Nov. 23, at 12:39 a.m. EDT (0539 GMT), but will appear full the night before and after its peak to the casual stargazer. The November full moon is often known as the Full Beaver Moon, though like all full moons on the calendar it has several other names in different cultures.
