New Moon: This is the period when there is no moon visible in the sky. This period is
also called the Dark Moon.

Full Moon: This is the night when the entire moon is completely visible in the sky.
Although on some nights, the moon may appear to be completely visible, there is
only one night when the moon is truly "Full".

Waxing Moon: This is the period when the moon grows from the New Moon to the
Full Moon.

Waning Moon: This is the period when the moon shrinks from the Full Moon to the
New Moon.

First Quarter: This is the halfway point between the New Moon and the Full Moon
when it is waxing.

Last Quarter: This is the halfway point between the Full Moon and the New Moon
when it is waning.

Blue Moon: This is the second of two Full Moons in one calendar month. A Blue
Moon is uncommon, hence the saying. "...once in a blue moon."

Black Moon: This is the second of two New Moons in one calendar month, also an uncommon occurance.
