Seasonal Blue Moon<\/h1>\n
\u00a0<\/p>\n
Most seasons, from solstice to equinox, or equinox to solstice, have three full moons, because the seasons last for approximately three months. Because of the unequal timing between the sun and the moon (our solar based years do not match up with the lunar months) a single season does not actually equal three lunar months, only three \u201csolar months\u201d. There are more than 3 lunar months in a season, not much more, but it is still more. If it lines up right\u2026<\/p>\n
We get four full moons in a single season instead of three. When this happens, the third full moon of that season is the blue moon.<\/p>\n
This is the original and old blue moon. Since the third full moon of four in a season is the blue moon, this means they always occur about a month before the solstice or equinox and can only happen in February, May, August or November. The reason the third moon is counted as the blue moon is actually due to the Christian calendar, it\u2019s all about the timing of Easter based on the Paschal moon.<\/p>\n
\u00a0<\/p>\n
Monthly Blue Moon<\/h1>\n
\u00a0<\/p>\n
The new blue moon seemingly arose out of a misunderstanding. An amateur astronomer, using information that was missing pieces, made a logical assumption and wrote about it in an article about the blue moon in Sky & Telescope.<\/p>\n
Accordingly, a blue moon occurs when there are two full moons in a single (named) month. The second of those full moons is the one called Blue Moon.<\/p>\n
Though this is the new version, it is just as rare as the seasonal blue moon, and it is also the more well-known version, so it is truly up to the individual which blue moon they which to observe, if any, or perhaps both.<\/p>\n
The monthly blue moon usually means something else which is just as interesting to me.<\/p>\n
\u00a0<\/p>\n
Thirteen Moons<\/h1>\n
\u00a0<\/p>\n
Our solar based year does not match up perfectly with the lunar months. One lunar month takes about 29.5 days, give or take about 6 hours. This equals out to about 12 and a half lunar months in a single year. A bit more than our Gregorian solar based months.<\/p>\n
Generally, in a single solar year, from January to December, there will be 12 full moons. But, because there are actually 12.5 lunar cycles in those 12 months, we will occasionally get it all lined up perfectly so as to have 13 full moons in the year.<\/p>\n
Most years in which we have a monthly blue moon will also have 13 full moons in the year \u2013 unless of course there is a missing full moon.<\/p>\n
Similarly, the tropical years (that is the seasonal years, say winter solstice to winter solstice) also hold, usually, 12 full moons, but, as with the normal year, can occasionally have 13 full moons.<\/p>\n
\u00a0<\/p>\n
Dual Blue Moons<\/h1>\n
\u00a0<\/p>\n
It is possible, but even rarer than either type of blue moon, for both types of blue moons to occur in a single year. For this to be possible there must be 13 full moons in a calendar year, but also 13 full moons between two December Solstices.<\/p>\n
\u00a0<\/p>\n
Black Moon<\/h1>\n
\u00a0<\/p>\n
That is a lot of focus on the full moon, which stands to reason, it is the most noticeable of the lunar phases and evokes all sorts of wonder and awe in a person. But within much of Paganism there is another moon phase that is just as important as the full moon.<\/p>\n
The Dark Moon (or astronomical New Moon). Just like the full moon can be seen twice in a single month, or season, or missing from a month and be counted 13 times in a year \u2013 so can every other lunar phase, and this includes the dark moon.<\/p>\n
So it is that the relatively new term of Black Moon refers to several of these things, just like blue moon has two meanings, so the black moon has several meanings.<\/p>\n
The most obvious are, Monthly Black Moon: This is of course the equivalent to the monthly blue moon; when we have two dark moons in a single calendar month. Seasonal Black Moon: Again this is equivalent to the seasonal blue moon; the third of four dark moons in a single season.<\/p>\n
But there are two other things that can be referred to as the black moon.<\/p>\n
\u00a0<\/p>\n
No Full Moon<\/h2>\n
\u00a0<\/p>\n
The lunar month never reaches a full 30 days, it is always at least a few hours short. This means that there must be at least one of each moon phase in every month. Unless, of course, that month has less than 30 days.<\/p>\n
February is the only month that can have a lunar phase missing and of course this is most notable in the case of the full moon. And it\u2019s not just that February is missing its full moon that makes this special. For February to be missing the full moon, this means that the full moon must be at the very end of January and the very beginning of March \u2013 which also means that either January or March will be a monthly blue moon \u2013 and indeed quite often it means that both January and March are monthly blue moons.<\/p>\n
Those years would be especially interesting I think \u2013 13 full moons in a year, no full moon in February and 2 monthly blue moons.<\/p>\n
When February is missing its full moon, some people refer to the dark moon of that February as the black moon. I can\u2019t really agree with this terminology though. The dark moon is not doing anything special in this month, it\u2019s the full moon that is \u201cdoing\u201d something special. I could agree with the name of Black Month or Black February though \u2013 these or similar would make more sense.<\/p>\n
\u00a0<\/p>\n
No Dark Moon<\/h2>\n
\u00a0<\/p>\n
Similar to the above missing full moon in February, so it can happen that February has no dark moon. Some people call this a black moon.<\/p>\n
And once again I cannot bring myself to agree with the terminology being used here. There is NO dark moon in this month, so which moon, which date exactly is the black moon happening? The fact there is no dark moon actually means that February is filled with bright moons, sure some of those moons are almost dark, but they have those slivers of waxing or waning, they are still reflective moons, still bright, still visible. A month full of visible moons hardly conjures the idea of darkness or blackness. A bit of a misnomer in my opinion. If anything the month should have a label to do with brightness and light, not blackness and dark.<\/p>\n

Dates<\/h1>\n
These don\u2019t include exact dates \u2013 because of time zone differences, I felt it best to just mention the months for better accuracy. \u00a0It may also not include all dates.<\/em><\/p>\n May 2016 \u2013 Seasonal Blue Moon (3rd of 4 in a season) \u00a0<\/p>\n Something that stood out to me about these dates, are the ones for this year, 2016. We have a seasonal blue moon in May \u2013 which happens to coincide with The Rite of Her Sacred Fires, the internationally observed ritual in honour of Hekate Phosphorous. And we have a monthly black moon in October \u2013 here in my time zone, that black moon happens on Halloween, which is also Beltane \u2013 perhaps this would be more significant if it was Samhain here in Australia, but it\u2019s still curious either way.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n I can google search all of these moons and I certainly find a few Pagan sites that give information about them, how they correspond to Paganism. But there isn\u2019t a whole lot out there. From what I can tell, it\u2019s because there isn\u2019t much agreement on what they all mean. These are relatively new observances \u2013 even the seasonal blue moon is only 400 or so years old, as something that has been noted by humans (obviously it happened before we started paying attention though). Because they are mostly new things, that means we don\u2019t have much in the way of old lore to draw upon.<\/p>\n Pagans Path<\/a> mentions that to some Pagans the (monthly) blue moon represents a so called Grandmother Goddess \u2013 which is a merging of all three parts of the Triple Goddess. Others see the blue moon as representing the transition of Crone to Divine. And still others see the blue moon as a time of clearer communication between mortal and divinity. Whereas About Pagan\/Wicca<\/a> mentions that, though there is no overall significance to the blue moon in Paganism, some individual covens will perform initiation rituals only during a (monthly) blue moon.<\/p>\n
