Where did "once in a blue moon" phrase originate?



The phrase once in a blue moon pertains to an event that may happen very rarely or seldom or may not happen at all..After all when was the last time you saw the moon turned blue? The "blue moon" expression is old and dates back to medieval England. According to modern folklore, a blue moon is the second full moon in a calendar month. Usually, months have only one full moon, but occasionally, a second one sneaks in. Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a singe month. This happens every two and a half years, on average.

For example, in 2004, the month of July had two ful moons. The first happened in July 2, while the other one happened in Juy 31, which by definition is a "blue moon".

  1. Interesting, I had always thought the blue moon was the nights when the moon is not actually visible given that at least once a month the moon does not reflect any of the sun's rays and is therefore invisible, even at night. Guess I was wrong, will be coming back for other trivia.

  11. hi there Steve..according to research, the moon is not blue or bluish..the date of a full moon, all by itself does not affect its color..The moon in July 31 is pearly gray as usual...

  20. So instead of saying "once in two years and a half" it is better to say "once in a blue moon"
    Nice post..
    Or it is better to say "see you in a blue moon"
    than " see you in two years and a half"

    Hi, Just makin you laugh......Peace....
