"once in a very blue moon"
A few of my blogger/Facebook friends Deborah Godin and Beth Patterson, alerted me to the fact that there will be a "blue moon" tomorrow December 31, 2010. These days a "blue moon" is defined as the second full moon that occurs in a calendar month. These are pretty rare.
NASA has a great piece on the origin of the phrase "once in a blue moon" and the more recent association of it with the astronomical phenomenon of two full-moons in a single calendar month.
My favorite piece of music about a blue moon, is performed by Nanci Griffith and is called "Once in a very blue moon" a song which she co-wrote with folk singer Patrick Alger.
