Luke 24:20-21 proves the crucifixion was not on a Wednesday.
. . . And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him.
But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.
The third day since those things, crucifixion, was done was our Sunday.
The second day since those things, crucifixion, was done was our Saturday.
The first day since those things, crucifixion, was done was our Friday.
The day those things, crucifixion, was done was our Thursday.
Wednesday being the day before Thursday. Sunday being the fourth day from Wednesday.
