When is Easter Sunday?

1In 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. 2And, 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. 3His countenance was like lightning, and his raiment white as snow: 4And for fear of him the keepers did shake, and became as dead men. 5And the angel answered and said unto the women, Fear not ye: for I know that ye seek Jesus, which was crucified. 6He is not here: for he is risen, as he said. Come, see the place where the Lord lay. 7And go quickly, and tell his disciples that he is risen from the dead; and, behold, he goeth before you into Galilee; there shall ye see him: lo, I have told you. 8And they departed quickly from the sepulchre with fear and great joy; and did run to bring his disciples word. 9And as they went to tell his disciples, behold, Jesus met them, saying, All hail. And they came and held him by the feet, and worshipped him. 10Then said Jesus unto them, Be not afraid: go tell my brethren that they go into Galilee, and there shall they see me.
