Anno Domini (abbreviated AD ; Latin for "in the year of the Lord" or completely Anno Domini Nostri Iesu Christi , "in the year of our Lord Jesus Christ ") denotes the year counting of the Christian calendar , counted from the year of the birth of Jesus Christ . Ante Christum natum (abbreviated a. Chr. N. , Partly also AC ), conversely, denotes the count before the birth of Christ.
The Christian calendar does not recognize a year zero . The first “year of the Lord” begins in the year of Jesus' birth. Similar expressions in terms of content are Anno Salutis ("in the year of salvation") or Anno orbis Redemptoris (abbreviated AOR).
Formed similarly to Anno Domini , the additions "Anno dazumal", "Anno dunnemals" and "Anno tobak", all with the meaning "then", "in the past". Similar expressions are Anno snow ( derived from Anno salutis ) or in Olim's time .
