Esther 3:12

Currently 13 is considered to be an unlucky number. It used to be--and in some earth-worshipping, i.e., pagan, religions still is--a lucky and magical number. Consequently there were 13 months and 13 zodiac signs (the Gemini twins had separate identities). Knowing how Christianity and other god-as-a-man-based religions were prone to say that what the pagans (Earth-and-god-as-a-woman) considered good was bad, this was probably the case with the number 13. Also, it is reflected so many times on the U.S. $1 bill-- 13 levels in the pyramid, 13 stars, 13 arrows, 13 stripes, 13 leaves, and 13 olives because of the original 13 colonies.

Thirteen is the 6th smallest prime number; the next is seventeen. 13 is the second Wilson prime. 13 is the fifth Mersenne prime exponent, yielding 8191. 13 is also the third lucky prime.

13 is the second star number and the seventh Fibonacci number. As it is an odd-indexed Fibonacci number, it is a Markov number, appearing in solutions to the Markov Diophantine equation: (1, 5, 13), (1, 13, 34), (5, 13, 194), ...

There are 13 Archimedean solids.

13 goes into 999,999 exactly 76,923 times, so vulgar fractions with 13 in the denominator have six digit repeating sequences in their decimal expansions. It is thus the smallest half period prime (integer sequence A097443).

13 is the largest number whose factorial is less than 1010. This means 13! is often the largest factorial a pocket calculator can represent without scientific notation.

At 13, the Mertens function sets a new low of -3, subseded later at 31 with a value of -4.

13 is the only positive integer that is the fourth root of the sum of the squares of two successive positive integers (119 and 120).

The 13th root is the most famous integer root calculation record, because 13 is the first prime number over 10 such as the last digit of a 13th integer power is the same as the last digit of its 13th root.

In base 10, the smallest prime with a composite sum of digits is 13.

13 is a repdigit in base 3 (111).

"So how did Friday the 13th become such an unlucky day?

Dossey, also a folklore historian and author of Holiday Folklore, Phobias and Fun, said fear of Friday the 13th is rooted in ancient, separate bad-luck associations with the number 13 and the day Friday. The two unlucky entities ultimately combined to make one super unlucky day.

Dossey traces the fear of 13 to a Norse myth about 12 gods having a dinner party at Valhalla, their heaven. In walked the uninvited 13th guest, the mischievous Loki. Once there, Loki arranged for Hoder, the blind god of darkness, to shoot Balder the Beautiful, the god of joy and gladness, with a mistletoe-tipped arrow.

"Balder died and the whole Earth got dark. The whole Earth mourned. It was a bad, unlucky day," said Dossey. From that moment on, the number 13 has been considered ominous and foreboding."

This is the way I read it:
Back in the caveman times, it was first considered unlucky. They counted their fingers, 10, and then their two feet, ending up with 12. Anything beyond was the unknown, and the unknown is sometimes scary(I can't think of a better adjective, sorry). So therefore, thirteen was unknown, scary, and basically unlucky. So yeah, that's what I heard. I have no idea if it's right but yeah. Ciao.
