I don’t think that the year Christ died, or even the day, matters. We know He rose on the first day of the week. But it is interesting to look at. Here is how I view the occurrences:
Tuesday - The Passover and Unleavened Bread (notice Mark combines the two…Luke does as well) when the priests conspired to kill Jesus. Their concern was that this not occur during the festival (15-21 Nisan, or Saturday to Friday). Mark 14:1-2
Thursday – Around 1 to 2 pm (evening of 14 Nisan) the Passover would have been killed per Jewish law (per the law that they had added to God’s Law).
Around this time Jesus sent two disciples to seek out where they would have the supper (it was already prepared). A few hours later, in the evening, Jesus arrived with the Twelve. “In the evening” typically means “between the evenings”, BTW.
Jesus observed Passover with the Disciples, went to the Garden, and was arrested by the priests. This is 14 Nissan, but Thursday night by our days.
Friday – Early in the morning the priests took Jesus to the Roman authorities. Around 9 am (the 6th hour, per John 19:15) Jesus was presented to His accusers who cried out “Crucify Him”, and He was handed over for crucifixion.
Around 3 pm (the ninth hour) Jesus cried out “Eloi, Eloi, Lama Sabachthani?” and died.
This is a day of preparation as the Sabbath (Saturday) was the next day. This particular Sabbath was a “high day” (another holy day treated as a Sabbath was on the same day, that is the 15th of Nisan). Joseph asked for and was granted Jesus’ body. Nicodemus brought spices. There was a tomb very close, owned by Joseph, which was important because they needed to conduct the burial before the Sabbath began.
Joseph and Nicodemus (probably with servants) lay Jesus’ body in the tomb, wrapped it and used spices. The women followed them there and saw how the body lay. The women returned and mixed spices for anointing Jesus after the Sabbath.
Saturday – This is 15 Nisan. It is a day of the holy assembly and it falls on the Sabbath in 33 AD.
Sunday – Jesus rose from the grave, having spent 3 days and 3 nights (according to Jewish time keeping) in the grave. Jews used “night-days” to measure time. A portion counted as a whole (this is obvious looking at Ester’s fast for “three days and three nights”). This would have been about 3 hours on Friday, all day Saturday, and part of Sunday. This is not an idiom but a Hebraism. It is how they counted night-days.
