How did Friday the 13th get its unlucky reputation?

According to National Geographic Kids, the exact origin of Friday the 13th as an unlucky day is unknown, but “it probably originates from the Christian religion.”

“In the Bible, for example, Judas – a person who is said to have betrayed Jesus – was the 13th guest at the Last Supper. Also, many unfortunate things happened on Fridays in the Bible,” says National Geographic Kids.
