Regarding the chronology of Jesus, the Gospel of John (e.g., , , ) implies that Nisan 14 was the day that Jesus was crucified in Jerusalem, while the Synoptic Gospels instead place the execution on the first day of Unleavened Bread (). Both John and Synoptics agree that the day of crucifixion was on the day of the Preparation, which is the reason Christ and the two thieves had to be quickly taken off the cross and rushed into the tomb before the sun had set in John 19:42. By the time of Christ, many customs in regard to the festival had changed, notable among them the intermixing of the two festivals in some customs and terminology. The whole day of Nisan 14, when the passover lamb was to be killed, was often collectively referred to as the Passover, when in fact the passover was not a day but a meal eaten at the very end of the day and the start of Nisan 15.
