Moon Cycles

r/MoonCycles

According to astrology, the moon's cycle can affect the way we feel about things. In particular, when the moon is full or new, both males and females can experience dramatic changes in their mood and behavior. This complete lunar cycle (New Moon to New Moon) is also called a "lunation". During this time the moon will completely circle the earth. That's the scientific definition, but you can take any phase; for instance a so-called "full moon cycle" would be from Full Moon to Full Moon.

The term "moon cycle" (or "lunar cycle") refers to the moon's continuous orbit around the earth. As the moon orbits the earth, its appearance (the "phase") changes and thus gives us an indication of the moon's progress in the cycle (the "age").

We give the parts of the moon cycle different names, according to how the moon appears to us. In order of appearance:

New (also called the Dark Moon) - not visible Waxing Crescent First Quarter - commonly called a "half moon" Waxing Gibbous Full - we can see the entire illuminated portion of the moon Waning Gibbous Third Quarter - another "half moon", but the illuminated part is opposite of the First Quarter Waning Crescent New - back to the beginning
