How did Friday the 13th get its unlucky reputation?

According to National Geographic Kids, the exact origins of when Friday the 13th became thought of as unlucky are unknown, however it "likely comes from the Christian religion."

"For example, in the Bible, Judas — a person who is said to have betrayed Jesus — was the 13th guest at the Last Supper. Also in the Bible, many unfortunate things happened on Fridays," according to National Geographic Kids.

Dr. Phil Stevens, retired anthropology professor from the University at Buffalo and author of a book titled "Rethinking the Anthropology of Magic and Witchcraft: Inherently Human", spoke with USA TODAY last year about the holiday and why it is an example of "magical thinking."

Stevens said that he likes to think of the superstition around Friday the 13th as an example of magical thinking. He said that magical thinking is when someone believes is there is a causal relationship between two things that are otherwise unrelated. For example, Friday and 13 together take on a different quality when they fall on the same day.

He also said he thinks of it as a taboo, as superstition has a negative connotation, even when someone uses it to describe their own belief.
