There is a common expression in the English language referring to a blue moon. When people

say that something happens “only once in a blue moon

,” they mean that it happens only

very rarely, once in a great while.

This

has been around for at least a century and a half; there

are references to this expression that date from the second half of the nineteenth century.

The expression “a blue moon

” has come to refer to the second full moon occurring in any

given calendar month. A second full moon is not called a blue moon because it is particularly

blue or is any different in hue from the first full moon of the month. Instead, it is called a blue

moon because it is so rare. The moon needs a little more than 29 days to complete the cycle

from full moon to full moon. Because every month except February has more than 29 days,

every month will have at least one full moon (except February, which will have a full moon

unless there is a full moon at the very end of January and another full moon at the very

beginning of March). It is on the occasion when a given calendar month has a second full moon

that a blue moon occurs. This does not happen very often, only three or four times in a decade.

The blue moons of today are called blue moons because of their rarity and not because of their

color; however, the expression “blue moon” may have come into existence in reference to

unusual circumstances in which the moon actually appeared blue. Certain natural phenomena of

gigantic proportions can actually change the appearance of the moon from Earth. The eruption

of the Krakatoa volcano in 1883 left dust particles in the atmosphere, which clouded the sun

and gave the moon a bluish tint. This particular occurrence of the blue moon may have given

rise to the expression that we use today. Another example occurred more than a century later.

When Mount Pinatubo erupted in the Philippines in 1991, the moon again

took on

a blue tint.
