Passover begins Wednesday 4-6- at sundown
Biblical Alignment
Tuesday 4-5 is the day before passover.
According to Jewish law, the lamb of the Passover is slaughtered in the evening of the 14th of Nisan, which is the first month in the Jewish calendar, and it is then eaten in that night (Exo. 12:1-8). As the Jewish day is reckoned from sunset to sunset, this night represents the start of the 15th of Nisan. The Synoptics claim that after having the Passover meal with his disciples, Jesus was arrested later in that night, i.e. the night of the first day of the Passover (Mark 14:12-46; Matt. 26:19-50; Luke 22:7-54), and was crucified in the morning, that is on the morning of 15th Nisan.
