held on the evening before the crucifixion day (although, strictly speaking, in no Gospel is it unequivocally said that this meal took place on the night before Jesus died). A new approach to resolve this contrast was undertaken in the wake of the excavations at Qumran in the 1950s when Annie Jaubert argued that there were two Passover feast dates: while the official Jewish lunar calendar had Passover begin on a Friday evening in the year that Jesus died, a solar calendar was also used, for instance by the Essene community at Qumran, which always had the Passover feast begin on a Tuesday evening. According to Jaubert, Jesus would have celebrated the Passover on Tuesday, and the Jewish authorities three days later, on Friday. Humphreys has disagreed with Jaubert's proposal on the rounds that the Qumran solar Passover would always fall the official Jewish lunar Passover. 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 calendar, which is based on Egyptian reckoning. In a review of Humphreys' book, the Bible scholar William R Telford points out that the non-astronomical parts of his argument are based on the assumption that the chronologies described in the New Testament are historical and based on eyewitness testimony. In doing so, Telford says, Humphreys has built an argument upon unsound premises which "does violence to the nature of the biblical texts, whose mixture of fact and fiction, tradition and redaction, history and myth all make the rigid application of the scientific tool of astronomy to their putative data a misconstrued enterprise." Location According to later tradition, the Last Supper took place in what is today called The Room of the Last Supper on Mount Zion, just outside the walls of the Old City of Jerusalem, and is traditionally known as The Upper Room. This is based on the account in the Synoptic Gospels that states that Jesus had instructed two disciples (Luke 22:8 specifies that Jesus sent Peter and John) to go to "the city" to meet "a man carrying a jar of water", who would lead them to a house, where they would find "a large upper room furnished and ready". In this upper room they "prepare the Passover". No more specific indication of the location is
