Seventh Day Baptists (SDBs) are a Baptist denomination which observes the Sabbath on the seventh-day of the week—Saturday—in accordance with the Biblical Sabbath of the Ten Commandments (Exodus 20:8, Deuteronomy 5:12). The movement originated in mid-17th century England and spread within a few years to the British colonies in North America. Today, the Seventh Day Baptist World Federation represents over 50,000 members in 22 countries worldwide, of whom over 20,000 reside in India and almost 5,000 reside in the United States.
