This is the exact counterpart to the original definition of a Blue Moon, which is a full moon, a Black Moon however, is the third New Moon in an astronomical season with four New Moons or the second New Moon in the same calendar month. Because of time zone differences, the month they happen in can vary, depending on your location.
It may also refer to the absence of a Full Moon or of a New Moon in a month. About once every 19 years, there is no New Moon. This can only happen in February, as this is the only month which is shorter than a lunar month (lunation). When this occurs, both January and March have two New Moons, instead of just one. Also about once in every 19 years February does not have a Full Moon, instead January and March have two Full Moons, also known as double Blue Moon.
Again because of time zone differences, these Black Moons may not happen all over the world.
Black Moons come with intense energy shifts and a very powerful time to set intentions. It’s a great moment to start over, release old patterns and begin anew.
