Paul (of the NT) was the earliest recorded writer. He said that he received his ideas directly from the resurrected Lord; he did not receive his ideas from any human.
He is the first person who dreamt up this "Last Supper" and this was copied (virtually word-for-word) by the writers of the Synoptic Gospels (Mark, later by Matthew and many decades later by Luke) - none of whom was in attendance at this Meal. The writers of John's Gospel place this event at a different location.
The idea of Jesus' death being taking place at Passover time was Paul's idea; it most likely did not happen at that time. The writers were not present at many of the events described as taking place at the trial or at the pillow talk by Pontius Pilate's wife. There was no arrangement for the release of a prisoner, such as Barabbas (meaning "son of the father).
Do not build a chronology from such a feeble foundation.
