Moon cycle and phase
In 29.5 days the
Moon completes a full cycle of phases. This is called the
Lunar Cycle or synodic month.
This Lunar cycle originally inspired the concept of what we now
call a month. Month lengths in some historic calendars followed
motions of the moon.

How do we
know if the Moon is waxing or waning?
But be mindful
that this is the situation for the Southern
Hemisphere. On the Northern Hemisphere it is the other way
around. That is because people on the Northern Hemisphere are
"upside down" as compared to us in the south. Although the
northerners would probably prefer to say that we are "upside down",
hence the term "down under". Anyway, when you are in the Northern
Hemisphere, you will see the constellations and the Moon phases the
other way around than we see them here in the south. After all,
there is no up and down in space, is there?
