We just learned a little about the Lunar Eclipse.
A full moon happens about once every 29 days.
Since there are 28, 30 or 31 days in each month we usually see a full moon once every month.
The full moon happens because the sun is shining right on the part of the moon that we can see.
Sometimes the sun is shining on a different side of the moon that is not facing us, and we would not see the full moon.
