Was the Sabbath Day Nailed to the Cross?

No.

The bible passage below shows the evidence for Sabbath keeping after Jesus was taken down from the cross:

Luke 23:52-56 King James Version (KJV)
52 This man went unto Pilate, and begged the body of Jesus.
53 And he took it down, and wrapped it in linen, and laid it in a sepulchre that was hewn in stone, wherein never man before was laid.
54 And that day was the preparation, and the sabbath drew on.
55 And the women also, which came with him from Galilee, followed after, and beheld the sepulchre, and how his body was laid.
56 And they returned, and prepared spices and ointments; and rested the sabbath day according to the commandment.

The verse below writes that Jesus is worried about people fleeing persecution and breaking the Sabbath just before the world ends:

Matthew 24:20-21 King James Version (KJV)
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

Here is another verse that bares evidence of Sabbath observance in the New Testament:

Matthew 28:1 King James Version (KJV)
1 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.

Below is yet another Bible Passage that shows that the people didn’t anoint Jesus on the Sabbath, but waited until Sunday to do it, the First Day of the week:

Mark 16:1-2 King James Version (KJV)
1 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.
2 And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.

Hebrews states plainly that the Sabbath day remains to the people of God:

Hebrews 4:4-9 King James Version (KJV)
4 For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.
5 And in this place again, If they shall enter into my rest.
6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
7 Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
8 For if Jesus had given them rest, then would he not afterward have spoken of another day.
9 There remaineth therefore a rest to the people of God.
