| A.D. |
A.D. is an abbreviation of the Latin words "anno domini." The abbreviation A.D. is used in dates when people are talking about things in history that happened after Jesus Christ was born. The year that Jesus Christ was born is called "1 A.D." The year after that is called "2 A.D." Jesus Christ is considered both God and man in the religion of Christianity, and he is an important figure in the history of the world. The calendar that most people use nowadays was created by Christians. That's why the year of Christ's birth was chosen as a way to divide older times from newer times. This calendar is not the first or only calendar that people in the world have created, but most people nowadays use this particular calendar. Instead of "A.D.," though, people often use "C.E." nowadays, which stands for "Common Era" or "Christian Era." |
