The crucifixion's proximity to the Sabbath day has also factored into the theory. Mark 15:42 indicates that Jesus was crucified on "Preparation Day (that is, the day before Sabbath)." Since the Sabbath occurs on Saturday, it was presumed that Jesus was crucified on Good Friday. The Wednesday Crucifixion theory accounts for this by translating "(μεγάλη ἡ ἡμέρα" John 19:31 as a special sabbath or High Holyday. Proponents of the Wednesday crucifixion theory argue that this special Sabbath was the Feast of Unleavened Bread, which commenced on the 15th day of the Jewish month of Nisan and was preceded with a passover meal on the 14th of Nisan. If Jesus was crucified in 30 A.D. or 31 A.D., the 14th of Nisan would have fallen on a Wednesday, with the next day being an Annual Sabbath.
