(CBS-Philadelphia) -  Do you suffer from friggatriskaidekaphobia? That is, a morbid, irrational fear of Friday the 13th?

This Friday the 13th is an unusual day for the superstitious, and extra spooky! It’s Friday the 13th and there is a full moon tonight. This won’t happen again until August 13, 2049. The last time it happened was October 13, 2000.

Ed Guinan, professor of astronomy and planetary science at Villanova University in Philadelphia says, “There is absolutely no evidence that Friday the 13th is bad luck and there’s no evidence really that the full moon effects human behavior.”

Linda Lee, a folklorist in Temple University’s Intellectual Heritage Foundation, says there are beliefs that contribute to the unlucky label. First, Friday was bad because Christ’s crucifixion happened on a Friday.

As for the number 13, “We see the number 12 as signifying wholeness or completeness in terms of thinking about the 12 apostles. The number 13 in the Medieval period came to signify something much less good, much less whole, in part because it’s one off.”

Full moons in June go by a number of names. Often called Rose Moon, Strawberry Moon or Honey Moon–the US Naval Observatory says the humid midsummer air can add a slight pink color to the lunar surface.
