Matthew 12:40
For as Jonah was
three days and three nights in the belly of a huge fish, so the Son of Man will be
three days and three nights in the heart of the earth.
Friday evening to Saturday evening is one day, and Saturday evening to Sunday evening is two days, and Sunday evening to Monday evening is three days. Christ resurrection came anytime after Monday evening. The women did not attend Christ's grave on Sunday, because it was against the law.
Luke 23:56
Then they went home and prepared spices and perfumes. But
they rested on the Sabbath-s in obedience to the commandment.
Unleavened Bread
{Sunday} is also a Sabbath Rest Day, according to the law.
