On that Sunday, Luke 24:21, ". . . But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done. . . ." So the second day since would be Saturday. And the first day since would be Friday.
Pretty sure it was on Wed. 14th Nisan. Jesus was in the tomb for 3, 24 hour periods.
Thursday, evening and morning.
Friday, evening and morning.
Saturday, evening and morning.
Thursday was the high Sabbath, 15th Nisan. Friday the Jews came to Pilate and asked for the tomb to be sealed. The resurrection happened after 6pm Sat., the start of Sunday, and before dawn. The tomb was already empty when the woman arrived.
"The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulchre, and seeth the stone taken away from the sepulchre."
"Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them. And they found the stone rolled away from the sepulchre. And they entered in, and found not the body of the Lord Jesus."
"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. And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun. And they said among themselves, Who shall roll us away the stone from the door of the sepulchre? And when they looked, they saw that the stone was rolled away: for it was very great. 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. 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."
"In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre. And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it.
His countenance was like lightning, and his raiment white as snow: And for fear of him the keepers did shake, and became as dead men. And the angel answered and said unto the women, Fear not ye: for I know that ye seek Jesus, which was crucified. He is not here: for he is risen, as he said. Come, see the place where the Lord lay."
All 4 accounts show the woman came early Sunday morning before dawn. The Resurrection itself:
"Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils."
Early on Sunday would be soon after 6pm in the evening. To be 3 days and 3 nights, or 3 evenings and mornings, the time frame would have been from 6pm T, then F, then over Sat, at 6pm. Yet the stone was not rolled away, until the woman came the next morning while still dark.
I posted the accounts in this order: John, Luke, Mark, and Matthew. Starting out with least detail to the most detail. The woman may or may not have seen the angels roll the stone away, but they did have a conversation with the angels. Jesus had already risen before the angels came and rolled the stone away.
