As you know, the traditional belief is that Jesus was crucified on Friday and raised Sunday morning before dawn. I've seen some who claim a Thursday crucifixion. You are the first I've seen to claim Wednesday.
Many NT passages say that Jesus would be raised "on the third day." For example:
NET Bible writes:
Matt. 16:21 From that time on Jesus began to show his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests, and experts in the law, and be killed, and on the third day be raised.
Matt. 17:23 They will kill him, and on the third day he will be raised. And they became greatly distressed.
Matt. 20:19 and will turn him over to the Gentiles to be mocked and flogged severely and crucified. Yet on the third day, he will be raised.
Luke 9:22 saying, The Son of Man must suffer many things and be rejected by the elders, chief priests, and experts in the law, and be killed, and on the third day be raised.
Luke 18:33 They will flog him severely and kill him. Yet on the third day he will rise again.
Luke 24:7 that the Son of Man must be delivered into the hands of sinful men, and be crucified, and on the third day rise again.
Luke 24:46 and said to them, Thus it stands written that the Christ would suffer and would rise from the dead on the third day,
Acts 10:40 but God raised him up on the third day and caused him to be seen,
1Cor. 15:4 and that he was buried, and that he was raised on the third day according to the scriptures,
For an illustration of how this phrase "on the third day" was used, look at what Jesus said in Luke 13:32:
NET Bible writes:
Luke 13:32 But he said to them, Go and tell that fox, ‘Look, I am casting out demons and performing healings today and tomorrow, and on the third day I will complete my work.
According to this verse, it seems that the traditional Friday crucifixion fits NT usage of the term "the third day". He is crucified on Friday, in the tomb the next day, and raised on the third day.
