Some Christians also refer to this day as Black Friday or Holy Friday. Not to diminish the importance or significance of Christmas, but all of Christianity hinges on Easter. It is through the death and resurrection of Jesus that all of mankind is saved. His birth and horrific death were prophesied by the most ancient of Jewish scripture and it is written that at the moment Christ died the earth grew dark. When did all of this occur? Would you believe April 3, 33AD? Is that exact date recorded in scripture or history anywhere? No.
