Full Moons with No Name
Some years have 13 Full Moons, which makes at least one of them a Blue Moon, as it doesn't quite fit in with the traditional Full Moon naming system. However, this is not the only definition of a Blue Moon.
About every 19 years, there is no Full Moon in February. This is one of several definitions of the term Black Moon. The other definitions refer to a New Moon which does not fit in with the equinoxes or solstices, similar to a Blue Moon.
