I did some research
Basically;
A blue moon is when two full moons happen in the same month
A black moon is when no full moon happens within a month

I was going to ask the same thing. Even in the month of February, the lunar cycle would dictate either the first or last day of the month being full. hmmmm

Hope this helps folks:
From Wikipedia, the free encyclopedia
For the "Black Moon" anime characters, see Sailor Moon.
In astronomy, the term black moon is not well known nor frequently used. As a consequence it has no accepted definition, but seems to have occasionally been applied to at least four different situations:
the absence of a new moon or dark moon in a calendar month;
the absence of a full moon in a calendar month;
either the third or the fourth new moon or dark moon in a season that has four of them (a season normally has only three). This is in analogy to the term blue moon which is the third full moon in a season that has four;
the second occurrence of a dark moon or new moon in a calendar month; this in analogy to an improper use of the term blue moon which sometimes is applied to the second full moon in a calendar month.
A black moon by the first meaning can only occur in February, with the next taking place (according to UTC) in 2014. In that year January and March will each have a black moon according to the fourth meaning.
A black moon by the second meaning can only occur in February, with the next taking place in 2018. In that year January and March will each have a second full moon (sometimes called a blue moon).
The next black moon in the third meaning of the term will occur in the summer of 2006, with the third new moon of the season on August 23 (19:10 UTC) and the fourth on September 22 (11:45 UTC). The autumnal equinox occurs on September 23 (04:03 UTC).
The next black moon in the fourth meaning of the term, which can occur in any month except February, is set to occur on December 31, 2005 (03:12 UTC). The earliest following that event will occur on August 30, 2008 (19:58 UTC).
