Thirteen is considered unlucky because Jesus' entourage supposedly included 13 people - himself and the twelve canonical apostles, and he was betrayed by a member of that group.
Of course, when you include Mary Magdalene and the baby, the math no longer adds up, so it is just superstition after all.

This is not the only reason it's considered unlucky especially when we're talking about FRIDAY the 13th. You probably know all this anyway, but just in case:
Jesus was supposedly crucified on a Friday for one thing.
In numerology....twelve is considered a number of completeness, perfection and order. Consider the 12 signs of the zodiac, the twelve tribes of Israel (there's also a kabbalistic connection with the number 13 too), twelve gods of Olympus, etc....Thus...thirteen is consider a number of disorder, imperfection, etc.....Though the number thirteen COULD actually be conceived as a "totality" of sorts when considering the Kabbalistic tree of life. While there are ten "divine emanations" ( or "Sephiroth") on the "tree" itself, there is also the "three negative veils of existence" known as Ain, Ain soph and Ain Soph Aur. These "veils" are considered to be the ultimate, ineffable and unknowable reality. Whether they can be rightfully defined as "god" or not is an entirely different matter.
The Witches' sabbat traditionally included 13 people as well.
On Friday October 13th, 1307....King Philip ordered the arrest of Jacques De Molay and many other Knights Templars in France. This is also believed to be a major reason for the mystification of Friday the 13th. I believe there are other ones where the number 13th is concerned in particular. I can't recall off-hand, but I have a copy of Aleister Crowley's "777 and Other Oabalistic Writings" and I believe he said several things about the number 13 in that book.
