The blue moon is the second full moon of the same month.
“It only happens once, sometimes twice a year,” Burnett said.
“The moon has always been a mysterious orb in the sky, and it was always thought to have some sort of mysterious powers,” Burnett said.
This obsession with the moon dates back to Celtic traditions and the beginning of Christian All Hallows Day celebrated on November 1. The night before, All Hallows Eve, was considered by many to be originally a Celtic harvest festival, which gave the moon great relevance in everyday life.
“So because… the moon has always been so mysterious, it has been associated with Halloween.
And of course now we see that we have the Full Hunter’s Blue Moon on Saturday night, that makes it all the more spooky and you know, all the more Halloweenier, ”Burnett said.
Traditionally, hunters hunted for food this time of year using moonlight to help them.
Have you ever wondered where the saying once in a blue moon came from? According to Burnett, it comes from an old English word which meant betrayed.
“So that meant they thought it had betrayed the normal cycles of the moon by showing up, you know, once again. So it’s a theory of how the word came to be.
And is it blue? No, unless there’s ash or something in the air to make it look blue, Burnett said.
In addition to the rare Halloween full moon, remember that early on Sunday morning the clocks will also set back one hour.
