If a Blue Moon is defined as the second Full Moon in a calendar month, we can easily calculate the mean period for such events because: 1  The synodic period between Full Moons is 29.53 days. 2  There are 12 calendar months in a year of 365.25 days. 3  A mean calendar month is [math]\frac{365.25}{12}\approx30.44[/math] days.
However, there are 2 completely different ways of calculating which Full Moon is a Blue Moon. Blue Moon: The Full Explanation. 1  Blue Moon = The 3rd Full Moon in an astronomical season with 4 Full Moons. (versus the normal 3)  Blue Moon = The 2nd Full Moon in a month with 2 Full Moons.
