What is the meaning of the terms DC when specifying a year a?

The term "DC" stands for "Anno Domini," which is Latin for "in the year of our Lord." It denotes years in the Gregorian calendar that follow the traditionally recognized year of the birth of Jesus Christ. It's often used interchangeably with "AD" (Anno Domini) and signifies years after the start of this epoch. In contrast, "BC" (Before Christ) refers to years before this point.
