There are a lot of people who taboo "13", the reason is that, according to superstition, as long as the 13th day of the month,12 witches (witch) will hold a carnival night, the 13th devil satan will appear at the climax of the night, to bring disaster to people. Therefore, westerners not only taboo "13" days but also taboo "13" number. Case in point: many buildings in the West don't have a 13th floor. Many people also avoid Friday.
The Bible says that after God created the first man, Adam, he took a rib from Adam and made Eve. Adam was created on a Friday, and it was on A Friday that Adam and Eve ate the forbidden fruit, and it was on a Friday that they died. Cain, the son of Adam and Eve, killed his brother Abel on Friday the 13th. Judaism has an official break from Sunset Friday to Sunset Saturday, known as Saath. Because of the above legends, Westerners are very taboo on "the 13th" and "Friday." If "the 13th" happens to coincide with "Friday," it is considered more unlucky and is called "Black Friday." Black Friday now seems to mean more than just the day on which the 13th coincides with Friday. Many people call it the "worst day" Black Friday, whether it is the 13th or not, and whether it is a Friday. Analysts say the problem is not the magic of the dates but the psychology of those who avoid them. I thought "The 13th" and "Friday" were the worst days.
Not only ordinary people but also famous people are afraid of the 13th and Friday. Goethe was always asleep; Napoleon never used troops. Bismarck signed no treaty, not even a document that did not touch anyone's fundamental interests. Former US President Hoover Roosevelt was also superstitious. Some will recall that Roosevelt did not travel on the 13th of every month, although not every 13th was a Friday.
Friday and the unlucky number 13 represent bad luck, two unfortunate individuals who combine to make a super unlucky day. So, the 13th of any month that falls on a Friday is called "Black Friday." The Apollo 13 spacecraft was launched from the Kennedy Space Center in Florida on April 11, 1970. Some point to the near-disastrous Apollo 13 mission to the moon as proof that 13 is the unlucky number. In western eyes, Friday is an unlucky day, when some people will be unable to get out of bed because of fear, and others will refuse to fly, buy a house, or even buy stocks on the winning side.
And if Friday coincides with the 13th, it's a terrible day. Because people don't fly or do business as usual on this day, the loss of business can reach 800 to 900 million dollars. He estimates that this fear afflicts tens of millions of people in the United States. Desai, a folklore historian and author of "Fear and Fun," says the fear of Friday the 13th is deeply ingrained in ancient times.
Friday and the number 13 represent bad luck, two unlucky individuals who combine to make a super unlucky day. Desai traced the fear of 13 back to a Norse myth about 12 gods feasting in their paradise, Valhalla. Loki, who had not been invited, was the 13th guest at the party. When he arrived, he sent Hode, the God of darkness, to shoot Balde, the God of joy, with an arrow with a mistletoe tip. Balde died, and the earth was plunged into darkness and sorrow. From that moment on, the number 13 became ominous. Bible also mentioned the unlucky number 13, and Judas, the apostle who betrayed Jesus, was the 13th guest at the Last Supper.
Meanwhile, in ancient Rome, 12 groups of witches were said to have gathered, and the 13th was demonic. Thomas Fessler, a scientist at the University of Delaware's Mathematics and Science Education Resource Center in Newark, said the number 13 suffered an unfortunate fate because it came after 12. According to Fessler, number scientists consider 12 to be a "perfect" number, the 12 months of the year, the zodiac signs, the 12 gods of Olympus, the 12 workers of Hercules, the 12 tribes of Israel, and the 12 apostles of Jesus. Above 12, 13 becomes "slightly more than perfect, dot," and the number becomes unstable. The fear of 13 is still influential today. According to Desai's research, 80% of the buildings have no 13th floor. Many airports leakage after 13 doors, hospitals, and hotels there is usually no room number 13. In Florence, Italy street, the house number is 12.5, between 12 and 14 famous sonnets in France socialites, they once believed to be 14 guests at the dinner party can get rid of an unfortunate fate.
As for Friday, it is the day when the famous Christian Jesus got persecuted. Some biblical scholars believe Eve tempted Adam to eat the forbidden fruit on Friday. Perhaps the most significant belief is that Cain killed Abel on Friday the 13th.
