However, Humphreys has calculated that Jaubert's proposal cannot be correct, as the Qumran solar Passover would always fall after the official Jewish lunar Passover. Nevertheless, he agrees with the approach of two Passover dates, and argues that the Last Supper took place on the evening of Wednesday 1 April 33, based on his recent discovery of the Essene, Samaritan, and Zealot lunar calendar, which is based on Egyptian reckoning.  Humphreys' implication is that Jesus and other communities were following the original Hebrew calendar putatively imported from Egypt by Moses (which requires calculating the time of the invisible new moon), rather than the official Jewish calendar which had been adopted more recently, in the 6th century BC during the Babylonian exile (which simply requires observing the visible waxing moon). A Last Supper on Wednesday, he argues, would allow more time than in the traditional view (Last Supper on Thursday) for the various interrogations of Jesus and his presentation to Pilate before he was crucified on Friday. Furthermore, a Wednesday Last Supper, followed by a Thursday daylight Sanhedrin trial, followed by a Friday judicial confirmation and crucifixion would not require violating Jewish court procedure as documented in the 2nd century, which forbade capital trials at night and moreover required a confirmatory session the following day.
