What Does “Once in a Blue Moon” Mean?

At its core, the phrase “once in a blue moon” refers to something that happens very rarely. It’s often used to describe events, occurrences, or situations that are infrequent or uncommon. For instance, you might say, “I only go to the gym once in a blue moon,” meaning that you rarely make it to the gym.
The phrase paints a vivid picture. Just like the actual astronomical phenomenon of a blue moon, which occurs when a second full moon appears in a single calendar month (a rare occurrence), the idiomatic expression invokes the sense of something that is exceptional or not regularly seen.

The Origins of “Once in a Blue Moon”

The term “blue moon” has a fascinating background. Its origins can be traced back to ancient folklore and the almanacs of the 19th century. The term is believed to have originated from the 1946 edition of “Sky & Telescope,” which explained that a blue moon is the third full moon in a season that has four full moons. This definition helped solidify the phrase in popular culture.
However, it’s important to note that the term “blue moon” has had different definitions throughout history. In 1937, the Maine Farmers’ Almanac used it to refer to the second full moon of a month, further popularizing its current meaning. The phrase gained traction through various pop culture references, songs, and even literature, cementing its place in the English language.

The Blue Moon Phenomenon

So, what exactly is a blue moon? In astronomical terms, a blue moon occurs roughly every two and a half to three years, meaning it’s a relatively rare event, aligning perfectly with the phrase’s interpretation. The moon doesn’t actually appear blue; instead, it’s named for its rarity, much like the expression itself.

What Causes a Blue Moon?

A blue moon occurs depending on the timing of the full moon within the months of the year. Each month typically has one full moon, but some months can have two full moons. This is particularly true for months with 30 or 31 days. The extra full moon is called a blue moon. Unlike the “once every few years” event of a blue moon, full moons generally occur every 29.5 days, creating a scenario where a month can occasionally house two of them.

When Was the Last Blue Moon?

As of now, the last recorded blue moon occurred on August 22, 2021. The next blue moon is set to take place on August 30, 2023. Keep an eye out for these dates, as they’re interesting to mark on your calendar and a great opportunity to experience the rare beauty of a night sky featuring this unique phenomenon.
