What is a 'blue moon'?

barbs42

There is a full moon every 28 days. Most of the time there is one full moon within a given month. When a full moon comes at the begining of a month there is a possiblity that the next full moon will be in the same calender month. When a calender month has 2 full moons - the second full moon is called a blue moon. Apr 19 00, 12:37 PM

'Blue moon' also means a long time. Eg. "something that happens once in a blue moon almost never happens" http://www.wordwebonline.com/search.pl?w=blue+moon Dec 06 06, 6:13 AM

The term blue moon has at least four related meanings. One is a common metaphorical phrase for a rare event. Full moons are given names in folklore, and two definitions of blue moon are a name for a rare full moon that does not have a folk name. One modern blue moon definition is a result of a misinterpretation of the Maine Farmer's Almanac, where a second full moon occurs in a calendar month. The older definition of blue moon is for an extra full moon that occurs in a quarter of the year, which would normally have three full moons but sometimes has four. Oddly, it is the third full moon in a season that has four which is counted as the "extra" other full moon and named blue moon. According to certain folklore, it is said that when there is a blue moon, the moon has a face and talks to the items in its moonlight. http://en.wikipedia.org/wiki/Blue_moon Jan 28 08, 12:10 PM
