'Preparation' in the Bible

So Jesus said, "Leave her alone, so that she may keep it for the day of my preparation for burial.

(Now it was the day of preparation of the Passover; it was about the sixth hour.) And he said to the Jews, "Behold your king!"

Then the Jews, because it was the day of preparation, so that the bodies would not remain on the cross on the Sabbath (for that Sabbath was an important day), asked Pilate that their legs could be broken and they could be taken away.

So there, on account of the day of preparation of the Jews, because the tomb was close by, they buried Jesus.
