Depending on whom you ask, next month will have a "black moon," which isn't nearly as scary as it sounds. In this case, it simply refers to a month that lacks a full moon, but it can also describe a month with two new moons or the third new moon in a season that has four total (which is one more than the average three). Regardless of the definition you happen to be dealing with, its spiritual significance remains essentially the same. During a black moon, the energetic focus is on the new moon , the one phase in which the moon is completely invisible. This lunar phase is most closely associated with personal growth, self-improvement, and fresh starts.
