The 13th Moon, or “Blue” Moon can occur at any time during the year. A Moon is called Blue only when it is the second full Moon to take place that month (moon-th). The second New Moon in a month is known as a Black Moon. Blue Moons are considered to be stronger than regular Full Moons, and Black Moons are considered to be stronger than regular New Moons.
Below is a chart detailing the names associated with each of the moon cycles of the year. The “Witch” moon names are from The Witches Almanac. . “Almanac” names are from the Old Farmer’s Almanac, who claims that the names come from east coast Native American names. The “Celtic Tree” names are associated with the attributions from Robert Graves’ The White Goddess.
