Tag: Blue Moon

A “Blue Moon” refers to an event in which a second full moon appears within a single calendar month. This phenomenon is relatively rare, occurring approximately once every two to three years, hence the phrase “once in a blue moon” is commonly used to describe something that happens infrequently. The term has also been traditionally used to signify the third full moon in a season that has four full moons, rather than the usual three. Despite its name, a Blue Moon does not appear blue in color; the designation is purely based on its occurrence and does not imply any change in the moon’s appearance. The concept of a Blue Moon has cultural significance, often associated with uniqueness and rarity.
