A Blue Moon event is one of the most beautiful times to observe Mother nature show its beauty. This event will happen on Halloween’s Day.

So what is the blue moon?

A “Blue Moon” is a relatively infrequent phenomenon involving an additional full moon appearance within a given period of time. But what period? There are two meanings of the word, it turns out, and one was born out of the other’s confusion.

The older definition describes a Blue Moon as the third full moon that has four full moons in a season. Called a seasonal blue moon, according to NASA, that occurs once every 2.5 years. Most recently, during a single calendar month, the term Blue Moon was extended to the second Full Moon. Among full moons, there are about 29.5 days, which makes it rare for two full moons to fit into a 30- or 31-day month. (This means February never has a Blue Moon).

The almanac was following those guidelines on what each moon would name. The last full moon of winter, for example, had to fall during Lent; it was called the Lenten Moon. The first full spring moon was dubbed the Egg Moon — or Easter Moon, or Paschal Moon — which had to arrive shortly before Easter within a week. Until Yule, there was always the Sun, and after Yule the Sun. So when there were four moons in a particular season, the third one was dubbed a Blue Moon, so that the other full moons could occur at proper times relative to the solstices and equinoxes.

The Blue Moon next year will be a weekly Blue Moon. A new moon is set to take effect on October 1 and October 31, 2020. Because two full moons are scheduled for October, this latter full moon is dubbed the blue moon.

According to Philip Hiscock, a folklorist at Newfoundland’s Memorial University, the term ‘once in a Blue Moon’ has been used for more than 400 years. He explained in a 2012 essay in Sky & Telescope magazine that the first use of the word was almost like suggesting that the moon is made from green cheese — it meant something ridiculous. “He’d argue the sky is blue” was close to thinking, “He’d argue the black is white”.

According to Hiscock, the word changed to be similar to “never.” “If the moon is blue, I’ll marry you” was the equivalent of “I’ll marry you as the pigs fly”.

“Most Blue Moons look pale gray and white, inseparable from any other moon you’ve ever seen,” NASA says. “Squeezing a second full moon into a calendar month does not alter the moon’s physical properties, so the color remains the same.”

It points out the moon will look bluish, as it did after the Krakatoa volcano erupted in 1883. Mercury in the air was serving as a barrier, causing sunsets and the moon to turn green and blue all over the world, an occurrence that NASA said is believed to have inspired the word “blue moon.” Certain things, including forest fires and dust storms, would cause the moon to turn blue.

We won’t be able to catch another blue moon on Halloween night until 2039, according to AccuWeather meteorologist Brian Lada. With that vein, mark the calendars now.
