There are many Christians insisting that there is no significance in the duration between burial and resurrection of Jesus. But He claimed that to be as significant, as being the only sign proving that Jesus was the Messiah. As His only sign, to the skeptics, Jesus said He would be in the grave for three days and three nights (Matthew 12:38-40).
Christians celebrate Good Friday, considered as the day when Jesus was crucified. But Scriptures point to another day, other than Friday. When carefully analyzing details of the events, before and after His resurrection, the crucifixion could not have been on Friday.
All the four gospel books, clearly reveal that Jesus was handed over to the Roman soldiers during the night after He had celebrated the Passover, using the new symbols (see Matthew 26:20-47, Mark 14:17-43, Luke 22:7-47 John 13:1ff). It may not be possible to clearly understand, unless appreciative of what the Hebrew Passover was and how it was observed, in Jewish custom.
