Sabbath means REST and was never a day of "worship" so does it really count all that much. Jesus died to remove the laded burdens and burden laders.

XXXIII. I Peter and Paul do make the following constitutions.
Let the slaves work five days;
but on the Sabbath-day and the Lord's day
let them have LEASURE to go to church for instruction in piety
. [that One-Piece Pattern]
We have said that the Sabbath
is on account of the creation
and the Lord's day of the resurrection.
Chapter XXI.-Sabbaths Were Instituted on Account of the People's Sins, and Not for a Work of Righteousness.
"Moreover, that God enjoined you to keep the Sabbath,
and impose on you other precepts for a sign, as I have already said, on account of your UNrighteousness
and that of your fathers,-as He declares that for the sake of the nations, lest His name be profaned among them, therefore He permitted some of you to remain alive,-these words of His can prove to you: they are narrated by Ezekiel thus:
`I am the Lord your God; walk in My statutes, and keep My judgments,
and take no part in the customs of Egypt;
and they shall be a sign
between Me and you,
THAT ye may know that I am the Lord your God.
Notwithstanding ye rebelled against Me,
and your children walked not in My statutes,
neither kept My judgments to do them:
which if a man do, he shall live in them. But they polluted My Sabbaths.

And I said that I would pour out My fury upon them in the wilderness,
to accomplish My anger upon them;
yet I did it not; that My name might not be altogether profaned in the sight of the heathen.
I led them out before their eyes, and I lifted up Mine hand unto them in the wilderness, that I would scatter them among the heathen, and disperse them through the countries
because they had not executed My judgments, but had despised My statutes, and POLLUTED My Sabbaths,
and their eyes were after the devices of their fathers.
Wherefore I gave them also statutes which were not good, and judgments whereby they shall not live.
And I shall pollute them in their own gifts,
that I may destroy all that openeth the womb, when I pass through them.' (Ezek. xx. 19-26.)
