what is a blue moon?

Answer 1

Any time you have two full moons within a one month period. It happens "Once in a full moon"

Actually it happens several times per year, but that's where the term comes from.

Answer 2

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,and the other full moon occuring at the end of the same month.
But the occurance is not regular.In a span of 19 years,at least 8 months will have two full moons.Out of these, two months having a blue moon each will occur in a single year.The next occurance will be on 31 st,December,2009

Answer 3

The moons cycle being shorter than a month occasionally causes two full moons in the same month. This second full moon is commonly thought of as a blue moon. However, Wikipedia says;
"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."

Either way, it occurs very rarely, hence the use of the expression, "once in a blue moon."

Answer 5

The moon repeats a cycle for each phase every 27 days. On rare occasions there will be two full moons before the 27 days is over. The second full moon is called a "Blue Moon". It's very rarely ever blue.

Answer 6

A blue moon is a phrase used when there are 2 Full moons that occur in one month, and for those that got a thumbs down for this question you will get a thumbs up from me.

Answer 7

it's the second full moon in any month

Quite a rare event, especially in february!

the moon goes through a cycle once every 28 days approx, so if you have a full moon on the 1 st of the month, you get another on 29th

Answer 8

ONE ...... Blue Moon ice cream is the name of a number of bright blue colored flavors of ice cream. All of the varieties of Blue Moon are available almost exclusively in the mid-west United States.

TWO ......The most obvious meaning of blue moon is when the moon (not necessarily a full moon) appears to a casual observer to be unusually bluish, which is a rare event. The effect can be caused by smoke or dust particles in the atmosphere, as has happened after forest fires in Sweden in 1950 and Canada in 1953 and, notably, after the eruption of Krakatoa in 1883, which caused the moon to appear blue for nearly two years
