The Meaning Of A Blue Moon Is Both Scientific & Spiritual


You probably use the idiom "once in a blue moon" to describe something that happens only on rare occasions. You might have even hummed along with the song "Blue Moon" by Billie Holiday or taken a sip of the Belgian-style beer called Blue Moon. You hear about this mysterious blue moon all the time, but do you even understand what it really is? Luckily, the meaning of a blue moon does not disappoint; it's just as enchanting as it sounds.

There are several definitions of a blue moon, but the most commonly known one is a second full moon that occurs during one calendrical month in the year. On average, this cosmically coincidental event happens roughly every 2.7 years, so it's not exactly what I'd call "common," but it's certainly not so rare that you won't experience several of them during your lifetime. And we just so happen to have one coming up on Oct. 31, 2020 — AKA Halloween. Spooky.

Is A Blue Moon Actually Blue?

You're probably wondering if the moon will actually appear blue when it rises in the sky. Unfortunately, the color blue has nothing to do with this event in outer space and a blue moon typically looks like any other full moon: big, bright, and beautiful, but usually not so blue. (Though, apparently, the moon has appeared to be flushed in blue on a few occasions.)

What Is The Meaning Of A Blue Moon?

The blue moon on Halloween will have no astrological significance. This is because on Oct. 31, 2020, the blue moon will be calendrical rather than astrological, which is an important distinction that astrologers make. While a calendrical blue moon occurs a second time in one calendar month, an astrological blue moon is one that occurs a second time during one solar month, which is the period of time in which the sun passes through a zodiac sign. The next astrological blue moon won't occur until Aug. 22, 2021, but when that happens, it'll be a magical night.

An astrological blue moon amplifies the effect that its respective zodiac phase has. For example, the blue moon on Aug. 22, 2021 will exaggerate the characteristics of Leo, the fire sign represented by the lion, which can cause you to become more creative, dramatic, and passionate than usual. An astrological blue moon also magnifies the energy of whatever sign the moon is passing through, which, on Aug. 22, 2021, will be Aquarius. Since a full moon is symbolic of culmination, completion, and fruition, a blue moon in Aquarius will be one impressing your inner worlds with individuality, rebellion, and a concern for the world at large.

Even though the moon on Oct. 31, 2020 won't be an astrological blue moon, it'll still be a night of immense space influence and a real sight to see in the sky. Since it's on Halloween, it'll only add to the effect.
