"Saturday" and "Sabbath Day" sound enough alike that it should prompt someone who questions whether it's the seventh day of the week or not to look into it further. Please see the passage below about the Sabbath day (day of rest) that we have been
Commanded to keep (
Exod. 20:8-11).
Exodus 31:13-17
31:13 Speak thou also unto the children of Israel, saying, Verily My Sabbaths ye shall keep: for it [is] a "Sign" between Me and you throughout your generations; that [ye] may know that I [am] the "I AM" that doth sanctify you.
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.
31:15 Six days may work be done; but in the seventh [is] the Sabbath of rest, holy to the "I AM": whosoever doeth [any] work in the Sabbath day, he shall surely be put to death.
31:16 Wherefore the children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations, [for] a perpetual Covenant.
31:17 It [is] a "Sign" between Me and the children of Israel for ever: for [in] six days the "I AM" made heaven and earth, and on the seventh day He rested, and was refreshed.
Some clear signs Father (God) has given us all that Saturday is the Sabbath day so that we will honour our perpetual Covenant (everlasting contract) with Him.

The seventh day of the week, referred to today as "Saturday", is the weekly Sabbath day, also known as "the Lord's Day", because it's the day God raised Jesus from the dead. It is to be a day of rest, not a day to go to churches or synagogues, or mosques, or temples of any kind (nor should anyone go to those places any other day of the week).
