When your mom moons the mailman
yes
*Note* You cannot "see" a "blue" moon as in the colour. It is just a term - see related link. No "blue moons will occur in 2011. December of 2009 - it's when there are two full moons in one month.
A Blue Moon, that is if you mean two full moons in one month.
No. There are two New moons, on the 1st and 31st of the month,and one Full Moon, around the 16th and 17th.
The last one was December 31st 1990. The next one is December 31st, 2009.
The second full moon in a month is called a "blue moon."
January, 2012 has one full moon. Two full moons in one month only happens once in a blue moon.
A bluemoon is having two full moons in the same month.
A blue moon is a full moon that is not timed to the regular monthly pattern. Most years have twelve full moons which occur approximately monthly, but in addition to those twelve full lunar cycles, each calendar year contains an excess of roughly eleven days. The extra days accumulate, so that every two or three years (on average about every 2.7154 years) there is an extra full moon. The extra moon is called a "blue moon."
The question is a little vague; I'm going to assume you mean full moons. The synodic period (the time between two full moons) averages 29.53 days, which works out to about 12.4 of them per year. In any given calendar year there are either 12 or 13 full moons. 2014 is a "12 full moons" year; 2015 will have 13.
Its called blue moon.
