The astronomical phenomenon of a blue moon means that the moon will be blue for a month
Both a blue moon and a lunar eclipse occurred on the 31st of December, 2009
You might have already guessed that if a moon is called a blue one, it's actually not about its color. The thing is that a blue moon is the second full moon in a calendar month. It appears every two to three years.
So, why is it called "a blue moon"? The origin of the term is vague, yet the suggestion has been made that the word "blue" replaced the no-longer-understood belewe, which meant "to betray". So, the original meaning would then have been "betrayer moon", as a full moon normally appears just once in a month.
What are your thoughts on this subject?

of course it cannot actually be blue as it is made out of green cheese, or so we were told when I was a kid over 60 years ago.

Green cheese? How about cream cheese? Rochefort cheese?

Great explanation

But some that occurs once in a blue moon is rare
Bob Ehrenberger
Actually the 4th full moon in a quarter.

Believe the write-up re the frequency of a blue moon meant to say "two or three times a year" rather than "every two to three years."

JUST looked that up last year. My youngest granddaughter asked me about it.

The reason it was called the Betrayal moon was because it had to do with planting and harvesting season

I saw a true Blue Moon back in the late forty's as a teen ager, it was beautiful, however I got the answer wrong!
Jack Kircher
No, and it is not made from cheese, either. I did, however see it a bright orange color once, it was lovely! I was in Brazil at the time.

some times appear blue but that is may be caused by dust in atomsphere

Is that correct; every two or three years?? Should be every year once a year in a certain month. Moon months are 28 days = 364 days = 13 moon months (in 12 calender months).

Did'nt know it's known as a betrayer moon.
