Just like painting a beautiful landscape, we can appreciate these unique moments when they come around.

How often is once in a blue moon?

When a single month has two full moons, the second full moon is called a Blue Moon. It happens every 2-3 years. Originally, the Maine Farmer's Almanac defined a "blue moon" as the 13th moon in a tropical year(from winter solstice to winter solstice). Normally, each season would consist of 3 moons. In a season of 4 moons, the third would be considered blue. Blue ink was used to record this event in the almanac. As a reference to the event, though, the idiom "once in a blue moon" means rarely. There is no set amount of time.

What does once in a blue moon mean?

There are in fact two definitions for a blue moon. According to the more recent definition, a blue moon is the second full moon in a calendar month. For a blue moon to occur, the first of the full moons must appear at or near the beginning of the month so that the second will fall within the same month (the average span between two moons is 29.5 days) or it means every once in a while.A "blue moon" is when there are two full moons in one month. Since this is rare (actually once a year) the phrase "once in a blue moon" is used to say something rarely happens."Blue moon" appears to have been a colloquial expression long before it developed its calendrical senses. According to the Oxford English Dictionary, the first reference to a blue moon comes from a proverb recorded in 1528: If they say the moon is blue,We must believe that it is true. Saying the moon was blue was equivalent to saying the moon was made of green (or cream) cheese; it indicated an obvious absurdity. In the 19th century, the phrase until a blue moon developed, meaning "never." The phrase, once in a blue moon today has come to mean "every now and then" or "rarely"-whether it gained that meaning through association with the lunar event remains uncertain.
