Friday the 13th

From what I know, Friday 13 is considered a bad luck number because in the Last Supper, 13 persons sat in the table (Jesus and the 12 Apostles), the next day which was a Friday (According to Christian tradition), two of them died, as we know Jesus was one and Judas was the other.

As simple as that.

According to the Catholic Bible, the Prophecy said he will resurrect at the third day, not after three days, the first day was the Friday in which he died, the second day is the Saturday and the third day is the Sunday.

Protestant interpretation of "Tear this Temple down [i.e., kill Him], and in three days I will rebuild it" is different to ours, we believe it was an example related  to God's power using the Temple of Jerusalem which was the Jewish greatest pride, and not related to his own death.
