I believe Our lord's crucifixion was on the same day as the temple lamb was dispatched.(the Passover lamb was killed about 4 hours into our Lord hanging on the Cross) on the [ Passover Preparation day John 19;14]. ((14th day of Nisan.)) ( Or 9:00 am or 3rd hour Wednesday.) (gave up the ghost around 3;00pm or 9th hour and ((darkness was over the land 6th hr.to 9th. hr.)) (this wed. also known as Gentile reckoning)
(buried just before sunset (6:00 pm our wed.) the Passover feast began at sunset and began the 15th of Nisan. The 3 days to follow while Our Lord was or wasn't in the tomb.The Hebrew's feasted on the slain temple lamb of the Passover. This feast known as 'The High day' ( Yom tov=The Good Day)(( our Thursday)) The first feast of Passover, they (unknowingly) were symbolically eating his Body for all mankind. So the Blood of the Jew's Passover lamb was also offered on the Mercy seat sometime during the Passover before the resurrection.( I would have to research of when they offer the Passover lambs Blood and sacrifice the flesh on the fire at the temple)
Resurrection sunset 18 Nisan Jews first day of the week. (our sat.)
All 4 Gospels agree on the Preparation day of Passover. Mtt 27:62 Mrk 15:42 Luke 23:54 Jhn 19:31& 42
Hope it helps.
