Why is friday the 13th bad luck?
Friday the 13th is only bad luck for people who believe in the superstitions.
The origin of the taboo surrounding the number13 is said to trace back to the times of Jesus Christ’s life. Jesus was the 13th person to his 12 apostles during the Last Supper.
The superstition associated with Friday the 13th the day traces back to legend.
Friday the 13th might be a self-fulfilling prophecy. If you think bad things are happening to you, they probably are (just as if you don’t believe in it, the day will be no different).
