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.
About once every twenty eight days, the moon gives off its full light, hence the name full moon, showing to the Earth observer as a perfect white sphere with its craters gleaming elegantly. The term blue moon is used when this event occurs four times in one of the year's four seasons or twice in a month. Precisely, a blue moon happens on the third full moon of a season with four full moons or on the second full moon in one particular month. This doesn't mean, though, that you'll find the moon literally giving off blue light at those times of the year. slide 2 of 3.
