The problem arises when people take a man made invention like the Gregorian calendar and try to make it more authoritative than Scripture. Pope Gregory assigned the wrong date to the crucifixion.
This is what Jesus Himself said....
Matthew 12:40 For just as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth.
The chart fits with that completely showing that there is no discrepancy.
It is written
Matthew 12:40 For just as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth.
it is also written,
mathew 13:34
All these things Jesus spoke to the crowds in parables, and He did not speak to them without a parable.
