Happy Blue Moon!
While exact definitions are many and varied, mine means the second Full Moon in the same zodiacal sign. Full Moons usually happen in successive signs each month. But there are 30 degrees in each sign, and every so often you'll have a Full Moon occur at the beginning of a sign (on 6/21, it happened in 0 degrees 51 minutes of Capricorn) then the next Full Moon a month later at the end of the same sign (today- in 28 degrees 47 minutes of Capricorn). It happens every couple of years on average.
So if you only do something once in a Blue Moon, maybe today's the day... :)
