A Blue Moon, that is if you mean two full moons in one month.

One full moon to the next. Earth is going to have two full moons in December this year, 2009. They call that a "blue moon."
There were 13 full moons in 1982. The number of full moons varies each year. In 1983 there were 12 full moons and in 1984 there were also 12 full moons.
That would be 1,200 full moons at a rate of 12 full moons per year.

Mars has only two moons. We call them Phobos and Deimos.

No. There are two New moons, on the 1st and 31st of the month,and one Full Moon, around the 16th and 17th.
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.
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.
Because there is one full moon every 29 days, and each month is either 30 or 31 days. So February (with only 28 or 29 days) can NEVER have two full moons, and two full moons in one calendar month will only happen about once every 29 months; call it once every 2.5 years on average.
