The Sabbath is Saturday. But most all claiming to keep the Sabbath are just playing ego games.
Unless one is an Acts 2:38 Christian it doesn't really matter what they do. Many claim to be "keeping the sabbath" not realizing that if they have even turned on a light switch they have "broken the sabbath". The New Testament Christian is to keep every day holy.
Exodus 16:29 See, for that the LORD hath given you the sabbath, therefore he giveth you on the sixth day the bread of two days; abide ye every man in his place, let no man go out of his place on the seventh day.
Take a walk? You have broken the Sabbath!
Exodus 20:10 But the seventh day [is] the sabbath of the LORD thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that [is] within thy gates:
Exodus 31:14 Ye shall keep the sabbath therefore; for it [is] holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth [any] work therein, that soul shall be cut off from among his people.
Exodus 31:15 Six days may work be done; but in the seventh [is] the sabbath of rest, holy to the LORD: whosoever doeth [any] work in the sabbath day, he shall surely be put to death.
Exodus 35:3 Ye shall kindle no fire throughout your habitations upon the sabbath day.
Start your car or turn on a stove? Oopsie!!
Numbers 15:32 And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.
Numbers 15:35 And the LORD said unto Moses, The man shall be surely put to death: all the congregation shall stone him with stones without the camp.
Jeremiah 17:21 Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring [it] in by the gates of Jerusalem;
Jeremiah 17:22 Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
Matthew 11:30 For my yoke [is] easy, and my burden is light.
Matthew 12:1 At that time Jesus went on the sabbath day through the corn; and his disciples were an hungred, and began to pluck the ears of corn, and to eat.
Matthew 12:2 But when the Pharisees saw [it], they said unto him, Behold, thy disciples do that which is not lawful to do upon the sabbath day.
Matthew 12:3 But he said unto them, Have ye not read what David did, when he was an hungred, and they that were with him;
Matthew 12:4 How he entered into the house of God, and did eat the shewbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests?
Matthew 12:5 Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?
Matthew 12:6 But I say unto you, That in this place is [one] greater than the temple.
Matthew 12:7 But if ye had known what [this] meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless.
Matthew 12:8 For the Son of man is Lord even of the sabbath day.
Matthew 12:9 And when he was departed thence, he went into their synagogue:
Matthew 12:10 And, behold, there was a man which had [his] hand withered. And they asked him, saying, Is it lawful to heal on the sabbath days? that they might accuse him.
Matthew 12:11 And he said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift [it] out?
Matthew 12:12 How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days.
John 5:10 The Jews therefore said unto him that was cured, It is the sabbath day: it is not lawful for thee to carry [thy] bed.
John 5:16 And therefore did the Jews persecute Jesus, and sought to slay him, because he had done these things on the sabbath day.
John 5:18 Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.
John 9:16 Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath day. Others said, How can a man that is a sinner do such miracles? And there was a division among them.
Colossians 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]:
1 Peter 2:5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
1 Peter 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
The real Acts 2:38 Christian is a part of a royal priesthood.
Matthew 12:5 Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?
I hope this helps...
