1570s, from Latin Anno Domini "Year of the Lord." Put forth by Dionysius Exiguus in 527 or 533 C.E., but used at first only for Church business. Introduced in Italy in 7c., France (partially) in 8c. In England, first found in a charter of 680 C.E. Ordained for all ecclesiastical documents in England by the Council of Chelsea, July 27, 816.\n
\nThe resistance to it in part might have come because Dionysius chose 754 A.U.C. as the birth year of Jesus, while many early Christians would have thought it was 750 A.U.C. [See John J. Bond, "Handy-Book of Rules and Tables for Verifying Dates With the Christian Era," 4th ed., London: George Bell & Sons, 1889] A.C., for Anno Christi, also was common 17c.

A.D. (1985) is a British/Italian miniseries in six parts which adapts the narrative in the Acts of the Apostles. Considered as the third and final installment in a TV miniseries trilogy which began with Moses the Lawgiver (1974) and Franco Zeffirelli's Jesus of Nazareth (1977), it was adapted from Anthony Burgess's novel The Kingdom of the Wicked, which was itself a sequel to Burgess's book Man of Nazareth, on which was based Zeffirelli's movie. The title is the abbreviation for Anno Domini ( Medieval Latin, "In the year of the Lord"), as the events occur in the first years of the Christian Era.
A.D. is Solace's sixth studio recording and their third LP. Referred to as "captivating from the first note" and "a defining moment in underground heaviness", "A.D." was recorded at New Jersey's Trax East Studios, Mad Oak Studios in Allston, Massachusetts, and Semaphore Studio in Chicago, IL over the course of 4 years.
