Every year, millions of people around the country spill into streets, dressed as fairies, goblins, characters from their favorite movie franchise, and everything in between.
Partying and making mischief.
But outside of a good time, how many know why they do it?
Today, Halloween is a billion-dollar industry.
But exactly how did it get there?
While today Halloween is synonymous with commercialism, it wasn't always that way.
The word Halloween comes from the words hallow, meaning Holy person, and een, deriving as a contraction of eve.
And All Hallows' Eve finds its origins all the way back in the time of the ancient Celtic pagans with the holiday of Samhain, a three-day fire festival that essentially celebrated death and rebirth.
The Celts, who lived in what is now Ireland, Scotland, the UK, and parts of Northern Europe, based their calendar on the wheel of a year.
Essentially divided into two halves, the light and the dark.
