Well, isn't that a delightful question! A "blue moon" is when we have two full moons in the same calendar month, which happens about every 2.7 years. So, the phrase "once in a blue moon" simply means something that doesn't happen very often, like a rare and special treat. Just like painting a beautiful landscape, we can appreciate these unique moments when they come around.


Why does the moon sometimes seem blue?

The term "blue moon" refers to the second full moon in a calendar month, which happens roughly every 2.7 years. The moon does not actually appear blue in color. The phrase "once in a blue moon" has led to the misconception that the moon can appear blue at times.


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.
