Every month of the year has a full moon, and each one has its own distinct name. The lunar phases have been used to keep track of each month for ages, from January's Wolf Moon through September's Harvest Moon and December's Cold Moon. According to National Geographic, "old societies all across the world have given these full moons names depending on the behavior of the flora, animals, or weather during that month." When you see a full moon in November, you may boldly point to the sky and wow your friends by pointing out the Beaver Moon.
