It would depend upon the religious belief of the one who asks the question. To the Jew the seventh day (Saturday) is the one to be observed, as it was commanded in the Law that was given to the Israelites that they should keep the seventh day as a holy day. That Law is still binding upon the Jews. If a Seventh Day Adventist, then let him keep the seventh day, for he believes that he is under the Law, and with that belief he certainly should keep the seventh day. To those who are members of some one of the various Protestant Churches, or of the Roman Catholic Church, let them observe the first day (Sunday) as the day of rest, as they believe that it is so commanded, and surely it would not be right for them to violate their conscience by doing otherwise. To the true Christian, the consecrated child of God, let these keep every day holy unto the Lord and not merely one day in seven. And let these enjoy a rest by faith in the Lord and in His sure promises. Let no one attempt to judge another in respect to this matter of ob serving the sabbath or holy days. No one has the right to judge his fellowman in this regard; but let every man be fully persuaded in his own mind (`Rom. 14:4,5`). If any one presumes to judge another in these matters, he is violating a direct command of the Lord as expressed by one of His inspired Apostles (`Col. 2:16`). If any one should say that we are not saved and that we are lost because we do not observe some special day, ask him gently but firmly–"Who made thee a judge?"
