Friday the 13th considered unlucky day, “why”

Friday the 13^th is the unlucky day of the year according to superstitions.it coincides with a full moon; keep away from your kids. Perhaps it is single most dreaded date on entire calendar. Three things need to happen; the day has to be a Friday, the moon has to be full and the date must be the 13^th. 

The full moon showed up at 12:11 a.m. ET, only for those who is living in Asia, Africa, Europe, South America and those in the Eastern Time Zone, experienced the full moon on June 13.  

No one knows about origin of the date, it came in minds first time in mid-19 when William Fowler, a US Army captain, founded the Thirteen Club - a group of 13 men in Manhattan devoted to proving that superstitions were false.

Those who believe in number 13, save our life from this number. Most of the hotels do not build the 13^th floor, they directly go to 14^th floor after 12^th, and even builders do not make after 12^th floor.

Legendary rapper Tupac was killed on Friday the 13th in Las Vegas. One superstition said if a child born on Friday the 13th will be unlucky for whole life.
