Why is Sunday "worship day"?

Normally, I answer my own questions, but I saw this link that had a great answer. Pay particular attention to this paragraph:

Scripture never mentions any Sabbath (Saturday) gatherings by believers for fellowship or worship. However, there are clear passages that mention the first day of the week, Sunday. For instance, Acts 20:7 states that “on the first day of the week we came together to break bread.” Paul also urges the Corinthian believers “on the first day of every week, each one of you should set aside a sum of money in keeping with his income” (1 Corinthians 16:2). Since Paul designates this offering as “service” in 2 Corinthians 9:12, this collection may have been linked with the Sunday worship service of the Christian assembly. Historically Sunday, not Saturday, was the normal meeting day for Christians in the church, and its practice dates back to the first century.

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.
