The Seventh-day Adventist Church is a Christian denomination with a worldwide membership of over 14 million and an active presence in most countries of the world.
The title refers to the Church’s belief in the imminent second coming (or “Advent”) of Jesus, and the observance of the “seventh day” of the week (Saturday) as the Sabbath. The denomination grew out of the Millerite movement in the United States during the middle part of the 19th century, and was formally established in 1863. (Source)
