Hi JosephMalik
When are all these things on the Jewish calendar?
The problem is that apparently was more than one Jewish calendar in use! The different gospels could be using different Jewish liturgical calendars to date events.
They were divided on many issues, especially with regard to the liturgical calendar.
The Sadducees and the priests who were in charge of the Temple followed a lunar calendar of 354 days. That calendar set the date of the Jewish festivals on the basis of lunar cycles. Thus Passover was celebrated on a different weekday (on the solar calendar) each year.
When the Dead Sea Scrolls were discovered at Qumran in the middle of the last century, they revealed that the Essenes, a Jewish sect of Jesus' time, had a different calendar. Theirs was a 364-day solar calendar. On this calendar, the festivals always occurred on the same day of the week.
The Jews who followed the Essene calendar always observed the Passover on Tuesday night (which for them was the start of Wednesday). Did Jesus use the Essene calendar and celebrate the Passover with His disciples on Tuesday? Was the Last Supper, therefore, held on Tuesday night instead of Thursday night? Some scholars argue rather persuasively that this is indeed what happened.
In support of their argument, they point out that an Essene community did live in Jerusalem, in the same part of the city where, according to tradition, the Upper Room was located. Jesus would have been aware that if He followed the Temple calendar, He would die before He could celebrate the Passover. It is possible He decided to follow the Essene calendar, celebrating Passover on Tuesday night.
This interpretation resolves two apparent chronological discrepancies between the Synoptics and the fourth Gospel. According to Mark 14:1, Christ's anointing at Bethany occurred "two days" before the Passover. Yet John 12:1 reports that event took place "six days" before the Passover. There would be no discrepancy if the Synoptics have in mind the Essene Passover on Tuesday, and the fourth Gospel the Temple Passover on Friday evening.
After His arrest, and before His crucifixion, Jesus was subjected to lengthy legal procedures. He was brought before Annas (see Jn 18:13,19-23); before Caiaphas (Jn 18:24); before the Sanhedrin (Lk 22:66-71); before Herod (Lk 23:6-11); before Pilate (Jn 18:28-40).
All this could hardly have taken place in only a night and part of a day. The theory that Jesus celebrated the Passover on Tuesday night allows time for all these proceedings.
Three ancient sources agree in saying that Jesus presided at the Last Supper on a Tuesday night: a second- or third-century document called the Didascalia Apostolorum; St. Victorinus (third century); and St. Epiphanius (fourth century). The first two sources also tell us this is why early Christians fasted and did penance on Wednesdays and Fridays. These two days bracketed the time of the beginning and end of Jesus' passion.
