"CE" stands for "Common Era," a designation used to denote years in the Gregorian calendar, which is widely used today. It is often used in place of "AD" (Anno Domini) to provide a more secular reference to the same time period. The Common Era begins with the year 1 CE, which is traditionally considered the year of the birth of Jesus Christ. The Common Era is part of a larger system that includes "BCE," or "Before Common Era," which refers to years before 1 CE. This system allows for a more inclusive way of discussing historical dates without religious connotations. Both CE and BCE are used in academic and historical contexts to promote clarity and neutrality.
