I am one who does not believe that Good Friday was the day that Jesus was crucified.
Matthew 12:38-40
38 Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.
39 But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:
40 For as Jonas was three days and three nights in the whale’s belly; so shall the Son of man be three days and three nights in the heart of the earth.
For the life of me I cannot find 3 days and 3 nights from Jesus' death to the time he resurrected. If Jesus died and was buried before Saturday began, He would have been in the tomb Saturday Night, Saturday Day, and Sunday Night only. For when Mary, Mary and Salome came to anoint Jesus at the rising of the sun on the 1st day of the week which was Sunday, Jesus had already risen.
Mark 16:1-7
1 And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, had bought sweet spices, that they might come and anoint him.
2 And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
3 And they said among themselves, Who shall roll us away the stone from the door of the sepulchre?
4 And when they looked, they saw that the stone was rolled away: for it was very great.
5 And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.
6 And he saith unto them, Be not affrighted: Ye seek Jesus of Nazareth, which was crucified: he is risen; he is not here: behold the place where they laid him.
7 But go your way, tell his disciples and Peter that he goeth before you into Galilee: there shall ye see him, as he said unto you.
The arguments I read which state that he was crucified on Wednesday are those that I find most credible.
From an LDS perspective, Joseph Smith stated:
From History of the Church on the 6th day of April of 1833, Joseph Smith says,
"The day was spent in a very agreeable manner, in giving and receiving knowledge which appertained to this last kingdom - it being just 1800 years since the Savior laid down His life that men might have everlasting life, and only three years since the Church had come out of the wilderness, preparatory for the last dispensation." History of the Church, vol 1, pg 337.
It is interesting how Joseph Smith uses the word, "just" in the phrase, "it being just 1800 years since the Savior laid down His life that men might have everlasting life". I believe that Joseph Smith not only believe that Christ was crucified in 33 A.D. but that he was also crucified on April 6th. The Church was restored on April 6th as well. In Joseph Smith's day they were using the Gregorian calendar. Under the Gregorian calendar the church was restored on April 6th. If you go to timeanddate.com and look up when April 6th was according to the Gregorian calendar in 33 A.D. you will find that it fell on a Wednesday.
