It's often overlooked that holy days were also Sabbath days, so Passover is a Sabbath, the first and last days of Unleavened Bread are Sabbaths, and the Feast of Firstfruits is a Sabbath. So the week of Jesus crucifixion would have included 4 Sabbaths.
The Jews therefore, because it was the preparation, that the bodies should not remain upon the cross on the sabbath day, (FOR THAT SABBATH DAY WAS AN HIGH DAY,) besought Pilate that their legs might be broken, and that they might be taken away... John 19:31
