Once in a Blue Moon is now!

A blue moon can refer to either the third full moon in a season with four full moons, or the second full moon in a month.^[

Two full moons in one month:^[

• 2009: December 2, December 31 (partial lunar eclipse visible in some parts of the world), only in time zones west of UTC+05.
• 2010: January 1 (partial lunar eclipse), January 30, only in time zones east of UTC+04:30.
• 2010: March 1, March 30, only in time zones east of UTC+07.
• 2012: August 2, August 31, only in time zones west of UTC+08.
• 2015: July 2, July 31

I'm not sure I ever knew what a Blue Moon was until I watched a "Pretender" TV episode a few years ago.  They used the 2 full moons in a month definition.

So this is the day to do all those things that you only do once in a Blue Moon!  Plus either now or wait funtil 2015.

I found an intersting article on the origin at http://www.skyandtelescope.com/observing/objects/moon/3305141.html?page=1&c=y.
