The term "Common Era" (CE) refers to the calendar system that is widely used today, starting from the year 1. It is a secular way of denoting years in the Gregorian calendar, which is based on the birth of Jesus Christ. The years before this point are labeled as "Before Common Era" (BCE), allowing for a non-religious reference to historical dates. The Common Era is used in various fields, including history, archaeology, and academia, to provide a standardized timeline. This system helps avoid religious connotations while still maintaining a clear chronological framework for events, cultures, and civilizations throughout history.
