I must disabuse you of the notion that Friday the 13th is somehow unlucky!
13 is linked to the lunar calendar (13 moons in a year) and is linked to women and moons. It is likey misogyny, beginning with mistrust of women and extending to all things female, that motivated people to think that the number thirteen is unlucky.
Not everyone thinks Friday the 13th is unlucky. It is Friday in some English-speaking cultures, Sweden, Russia, Belgium and Germany or a
Tuesday in the Greek and Spanish-speaking world.
Other people think of 13 as a very lucky number. (From Wikipedia)
Lucky 13
In Sikhism, the number 13 is considered a special number since 13 is tera in Punjabi, which also means "yours" (as in, "I am yours, O Lord"). The legend goes that when Guru Nanak Dev was taking stock of items as part of his employment with a village merchant, he counted from 1 to 13 (in Punjabi) as one does normally; and thereafter he would just repeat "tera", since all items were God's creation. The merchant confronted Guru Nanak about this, but found everything to be in order after the inventory was checked. April 13 also usually turns out to be Vaisakhi every year, which is the Sikh New Year and the major Sikh Holiday.
Several successful athletes have worn the number 13. Alex Rodriguez is said to be one of the most talented baseball players ever; he has also signed the biggest sports contract and wears the number 13. Dan Marino, an American football player known for passing more yards than any other quarterback in NFL history, wore the number 13, although pundits in the sport have often cited him as the greatest quarterback never to win an NFL championship. Basketball great Wilt Chamberlain wore the number 13 on his jersey throughout his NBA career. Also, FIBA rules require a player to wear the number in international competitions (only numbers from 4 to 15 could be worn, and as there are 12 players, one must wear 13); Chris Mullin, who wore #20 in college and #17 in the NBA, wore #13 for both (1984 and 1992) of his Olympic appearances. Shaquille O'Neal wore #13 in 1996, Tim Duncan wore #13 in 2004, Steve Nash is currently wearing it for the Phoenix Suns, and also Mats Sundin, wears 13 in the NHL. One of Iceland's all time best handball players, Siguršur Sveinsson, wore the number 13 when he played for the national team.
In Italy, 13 is also considered to be a lucky number.
Colgate University also considers 13 to be a lucky number. They were founded in 1817 by 13 men with 13 dollars, 13 prayers, and 13 articles. (To this day, members of the Colgate community consider the number 13 a good omen.) In fact, the campus address is 13 Oak Drive in Hamilton, NY and the all men a capella group is called the Colgate 13.
In tattoo culture, where symbols often represent the opposite of their most obvious meaning, 13 sometimes symbolizes good luck, especially in "old school" style tattoos.
So on with LUCKY Friday the 13th! If you can't go that far at least this will give you something to consider.
Thinking positive thoughts!
