But my question was about the timing of the crucifiction and the last supper, not about how the Jews and Romans differeed in their measuring of days.
In Matthew, Mark, and Luke, the last supper is a passover meal, but in John, Jesus is crucified before passover.
If you read John carefully, you will see that all of the important elements of the narrative are there; Jesus washing his disciples' feet, and the prediction of the disciple who would betray him to the Romans.
However, then the following line appears, emphasis mine:
John 13:29 For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor."
The "feast" he is talking about is the Passover feast, as is mentioned in the first line of chapter 13.
There is more:
John 19:14 And it was the preparation of the passover, and about the sixth hour: and he saith unto the Jews, Behold your King!
John 19:31 The Jews therefore, because it was the preparation, that the bodies should not remain upon the cross on the sabbath day, (for that sabbath day was an high day,) besought Pilate that their legs might be broken, and that they might be taken away.
John 19:42 There laid they Jesus therefore because of the Jews' preparation day; for the sepulchre was nigh at hand.
See, in the above passages, Passover had not happened yet, but in all of the other gospels, the last supper is a Passover meal.
Here is a line from Matthew's version of the last supper which states that it is a Passover meal:
Mat 26:19 And the disciples did as Jesus had appointed them; and they made ready the passover.
Right after this line, he sits down with the twelve and tells them that one of them will betray him, etc, etc.
This is a pretty big contradiction, don't you think?
Many Biblical scholars belive that the reason the timing of the crucifiction was changed in John was because it was clear by this point that Jesus wasn't a military leader who would be coming back to vanquish all of the Jews' foes, so he was being reformed as a spiritual, symbolic Passover sacrifice. It works better, then, if Jesus is killed before Passover rather than after, so John changed it.
