Florida Georgia Line is set to play the 2nd annual Buckeye Country Superfest in Columbus, OH June. 18th and 19th 2016! Joining them on the bill are country stars Jason.
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.
Technically each cardinal phase (First Quarter, Full, Last Quarter and New) are all momentary events. They occur at specific times and then pass immediately. A better way to ask the question is to ask how much time passes BETWEEN each phase. The answer to that question is 29.5 / 4 days. 29.5 days is the number of days that it takes for the moon to cycle through it's phases (called the synodic month)... The interstitial phases (Waxing Cresent, Waxing Gibbous, Waning Gibbous, and Waning Cresent) also last 29.5 / 4 days each... Hope that helps.
