(Fact and fantasy about blue Moons.)

Answer 2

A blue moon is the second full moon in a calendar month. To have a blue moon month there must be a full moon at the beginning of the month to have a full moon at the end of the month. There are only 41 blue moon months for every 100 years so the saying "once in a blue moon" means that it does not happen very often.

Answer 3

In a single calendar month, if two full moons occur ,then the second full moon is called a blue moon.This is likely to occur if the first full moon occurs on first day or the second day of the month,then the other full moon will occur at the end of the same month.
But the occurance is not regular to pinpoint.In a span of 19 years,at least 8 months will have two full moons.Similarly in a span of 19 years or so, a single year will have two blue moons.The next occurance will be on 31 st,December,2009.

Answer 4

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" 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.

The origin of the term blue moon is steeped in folklore, and its meaning has changed and acquired new and interesting meanings and nuances over time. The earliest known recorded usage was in 1362, in a pamphlet entitled Rede Me and Be Not Wrothe: "Yf they say the mone is belewe / We must beleve that it is true" [If they say the moon is blue, we must believe that it is true]. This implies the expression had a meaning of something that was absurd, and bears close resemblance to another moon-related adage first recorded in the following year: "They would make men beleue ... that þe Moone is made of grene chese". "They would make men believe ... that the moon is made of green cheese".


In recent times, people have taken to calling a full moon a blue moon based on the Gregorian calendar. By this use of the term, a blue moon is the second of two full moons to occur in the same calendar month.

Although the full moon that occurred Thursday, May 31, 2007, looked like an ordinary full moon, it was actually a bit extraordinary—a blue moon.

What is a Blue Moon?
There are in fact two definitions for a blue moon. According to the more recent definition, a blue moon is the second full moon in a calendar month. For a blue moon to occur, the first of the full moons must appear at or near the beginning of the month so that the second will fall within the same month (the average span between two moons is 29.5 days). May 2007 had two full moons: the first on May 2, the second on May 31—that second full moon was called the blue moon.

The Other Kind of Blue Moon
An older definition for the blue moon is recorded in early issues of the Maine Farmer's Almanac. According to this definition, the blue moon is the third full moon in a season that has four full moons. Why would one want to identify the third full moon in a season of four full moons? The answer is complex, and has to do with the Christian ecclesiastical calendar.

The term blue moon has at least four related meanings. One is a common metaphorical phrase for a rare event.

Answer 6

Blue Moons were "extra" full moons that occurred, giving a season 4 full moons instead of 3. This happens because the lunar year and the solar year are not the same length of time (they only coincide every 19 years, which the Druids referred to as a "Great Year").

Since they are so rare, the expression "once in a Blue Moon" has come to mean something that rarely occurs.

Answer 7

Its actually when there are two full moons within the same calendar month. Why it is called a blue moon, I don't know. It seems it might have been a corruption of another language. Also blue moons do happen. Check out your calendar at the moon phases.

Answer 8

Blue moon means nothing...
the phrase "Once in a Blue Moon..." means, im sure u know, that the event is very very unlikely to happen..

now the legend...

during partial Lunar Eclipses the moon turns copperish-red colour..and this occurs about 2-3 times a year..the ancients extended this to Green Moon and eventually to Blue Moon...
