There is so much folklore about Friday the 13th. Below are a few fun facts about the "scary" date.
" The ill-fated Apollo 13 launched at 13:13 CST on Apr. 11, 1970. The sum of the date's digits (4-11-70) is 13 (as in 4+1+1+7+0 = 13). And the explosion that crippled
the spacecraft occurred on April 13 (not a Friday). The crew did make it back to
Earth safely, however.
President Franklin D. Roosevelt would not travel on the 13th day of any month and would never host 13 guests at a meal. Napoleon and Herbert Hoover were also
triskaidekaphobic, with an abnormal fear of the number 13.
The number 13 suffers from its position after 12, according to numerologists
who consider the latter to be a complete number - 12 months in a year, 12 signs
of the zodiac, 12 gods of Olympus, 12 labors of Hercules, 12 tribes of Israel,
12 apostles of Jesus, 12 days of Christmas and 12 eggs in a dozen. "
