Thirteen is the number that pops out in everyone's mind when we hear the word “unlucky number”. Have you ever thought why are we afraid of the number 13??? Researchers say that back in 1990 and 1992 on the southern section of London’s M25 motorway the flow of traffic, injuries and the number of car accidents during the five months were on the 13th of Friday.

In some cases, the employees also avoid going to the offices to refrain from accidents. Moreover, in Greek culture, Tuesday 13th literally means ‘the third’, hence it is said that “Bad luck comes in threes.”

Believe it or not, nearly 10% of the citizens of the United States have the fear of Friday the 13th, which is called “Paraskevidekatriaphobia.” Moreover, 666 and the number 13 are considered to be the most Unlucky Numbers In America.

Number 4:

Next comes is the number 4. This number is considered bad luck in the Far East, in countries like China, Japan, Korea, Taiwan & a few other countries with Japanese or Chinese influence. But why is 4 unlucky said to produce such anxiety in the residents of these countries?? They believe pronouncing the number 4 is similar to the word death. Just like the U.S. buildings in these countries skip the 4th floor.
