Correct.
Sunday is the 1st day of the week.
Celebrating the Sabbath on Saturday
Q. Why don’t Latter-day Saints celebrate the Sabbath on Saturday like they did in the Bible?
A. (by Marc Schindler) In fact, as Jews themselves, Jesus and his disciples followers did observe the Jewish Sabbath. We know this from biblical references to both Jesus and His apostles teaching in synagogues. For instance, in Luke 4:17-23 we read that Jesus was teaching in a synagogue on the Sabbath.
But even as far back as Jesus’s ministry, He started deliberately but subtly challenging much of the rigidity of contemporary Sabbath law (see, for instance, the story of Jesus and the disciples plucking grain to eat on the Sabbath in Matthew 12:1-13). After His ascension, when the disciples went out to preach the Gospel, Gentile converts were not required to observe the Sabbath, although most Jewish converts continued to. This is highlighted in the famous vision shown to Peter, as recorded in Acts 10, where he is told by the Lord not to require Sabbath observation by Gentile converts.
So how did the day get changed from Saturday (the seventh day) to Sunday (the first day) amongst early Christians? In Acts 20:7 we read of a gathering of Saints in Asia Minor on Sunday; that it was a religious service is revealed by the fact that Paul preached during the meeting. Sunday was picked because it was the day of Jesus’s resurrection (see 1 Corinthians 16:1-2 and Revelation 1:10). Sunday became known as the Lord’s Day.
Most modern Christians, including Latter-day Saints, now follow a practice whereby Sunday, the first day of the week, is observed as the Lord’s Day. Technically speaking, this day isn’t the Sabbath, which is the seventh day; this is a distinction we rarely make today, but shouldn’t forget.
