In the Bible and according to Jewish Tradition Saturday was the day the God rested on the 7th day. When Jesus was Crucified it was on a friday.. he arose on Sunday. Christians then took the resurrection day to the Holy day of the week and made it their day of worship. In Islam the big Day of Worship I believe is Friday.
the sabbath was originally the seventh day, Saturday, but the pagans worshiped on Sunday,so there was an issue with trading and market days, so both sides agreed to worship on Sunday and trade on sat. the tradition sadly continues....
It's called a "Blue Law"....it was basically changed to accommodate the work week! Most people work on Saturdays so the church changed the sabbath from Saturday to Sunday. "blue laws" also restrict certain things like sales of alcohol on Sundays
It is meant for us to acknowledge our need for rest. To add my own embellishment I think it means something for it not to be mid week. That rest comes after work, in other words no procrastination. God bless.
Christians worship on Sundays in celebration of the resurrection of Jesus Christ. It is very important to remember, though, Sunday worship is not commanded in the Bible, and Sunday has not replaced Saturday and become the Christian Sabbath. While the New Testament describes Christians gathering and worshipping on Sundays, it nowhere states that Sunday has replaced Saturday as the Sabbath. They key point in all of this is that we are not to limit our worship to any particular day of the week. We are to rest in the Lord every day. We are to worship the Lord every day.

God showed man at creation the seventh day is the Sabbath, that is saturday. Look saturday in the dictionary, it says the seventh day of the week. Emperor Constantine decreed on 7March 321 that sunday would now be the day of rest in the Emperor, to be different from the Jews. Saturday is still the Sabbath of God He has never changed the day, so why should we?
