John reports the crucifixion of the Messiah Jesus on a Passover Friday, without specifying the year, but according to astronomical calculations and historical landmarks, two possible dates emerge in the period concerned: April 7, AD 30 and April 1, AD 33. The study of the prophecy of the seventy weeks presented in Daniel 9.24-27, which announces with remarkable precision the time of the coming and the putting to death of the Messiah, leads us to rule out the first date. Everything indicates that Jesus died on the cross on a Passover Friday, April 1 of the year 33, thus fulfilling the prophecy and coinciding with the feast on which the Passover lamb was to be sacrificed.
Our aim is to understand how the Passover feast unfolded that year and to explain the apparent differences between the account of the apostle John and those of the Synoptic Gospels. John states that the crucifixion took place on the day of preparation for the Passover, that is, on the eve of the , whereas Matthew, Mark and Luke seem to place the Lord's last meal during the feast itself (Matthew 26.17; Mark 14.12; Luke 22.7; John 19.14). This divergence, often noted, is not a contradiction but reflects complementary viewpoints according to the Jewish calendar and the religious context of the time. The Jews of Judea sometimes followed a different reckoning from that of the Galileans, and it is quite possible that Jesus and his disciples celebrated the Passover meal one evening earlier, in keeping with the Galilean calendar, while the religious authorities of Jerusalem observed the feast the next day. Thus Jesus would have celebrated the Passover on Thursday evening and died at the hour when the priests were slaughtering the lambs in the Temple precincts on Friday afternoon, perfectly fulfilling the symbol of the Lamb of God offered for the salvation of the world (John 1.29; 1 Corinthians 5.7).
To clarify the situation, it is useful to go back to the law of Moses, which set out the precise regulations for celebrating the Passover (Exodus 12.1-14; Leviticus 23.5-8; Numbers 9.1-14). The lamb was to be chosen on the tenth day of the month of Nisan and sacrificed on the fourteenth, between the two evenings, that is, in the late afternoon. The Passover meal began at sunset, marking the fifteenth of Nisan, the first day of Unleavened Bread. It is this gap between the moment the lamb was slaughtered and that of the meal that may have given rise to different interpretations. By insisting that Jesus died on the very day of the preparation of the Passover, John underlines the parallel between the death of Christ and the ritual sacrifice commanded by the law. The expression “before the feast of the Passover” (John 13.1) therefore refers to the Thursday set aside for preparations, while the crucifixion takes place the next day, on the real day of the Passover according to the priestly calendar.
This perspective brings out a remarkable consistency between the Gospel accounts. Matthew and John were direct witnesses of the events: Matthew saw the course of the Passion with his own eyes, and John stood at the foot of the cross beside Mary, the mother of Jesus (John 19.25-27). Mark relies on the precise testimony of Peter, who was also present at the scene (Mark 14.54; Mark 15.39-41), and Luke, although he was not a direct witness, took care to gather the testimony of those who had seen and heard (Luke 1.1-4). These four evangelists agree on the essential point: the crucifixion took place on a Friday, the day of preparation preceding the , during the feast of the Passover (Mark 15.42).
The spiritual meaning of this coincidence is profound. By dying on the very day when the Passover lambs were slain, Jesus perfectly fulfilled the figure announced for centuries. He became the true Lamb, the one whose blood protects and redeems, no longer a single people, but all of humanity (Isaiah 53.5-7; John 3.16-17). The calendar, the rites and the prophecies converge in this unique moment where history and divine revelation meet. Friday, April 1, AD 33 is therefore not only a historical date, but the culminating point of the plan of salvation established by God from all eternity.
