What is bce and ce

Understanding BCE and CE Dating

BCE (Before Common Era) and CE (Common Era) are dating designations used to mark historical time periods and distinguish between years before and after the conventional Christian calendar reference point. BCE and CE replaced the older BC (Before Christ) and AD (Anno Domini) terminology in modern academic and professional contexts. This transition represents a shift toward more neutral, inclusive language in global scholarly discourse while maintaining the identical chronological framework that enables effective historical communication and research.

The Transition from BC/AD to BCE/CE

For nearly two millennia, Western civilization used BC and AD to organize historical timelines. These Latin-based abbreviations carried explicit religious significance tied to Christian theology and the estimated birth year of Jesus Christ. Beginning in the late 1980s and accelerating through the 1990s and 2000s, major academic institutions, professional organizations, and scholarly societies officially adopted BCE/CE terminology. This change was motivated by a desire to create a secular, religiously neutral dating system that better serves diverse international academic communities while preserving the existing chronological framework.

How BCE and CE Work

• CE (Common Era): Includes years 1 through the present day, counting forward chronologically
• BCE (Before Common Era): Includes years before year 1, counting backwards (1 BCE, 2 BCE, 1000 BCE, etc.)
• The Transition: Year 1 BCE is immediately followed by year 1 CE, with no year zero in this system
• Equivalence: Year 1000 BCE equals 1000 BC; year 1000 CE equals 1000 AD; the dates are identical

Academic and Professional Adoption

Major universities including Harvard, Yale, and Oxford have officially adopted BCE/CE in their style guides and academic publications. The Chicago Manual of Style, widely used in academic publishing, recommends BCE/CE terminology. Professional organizations in history, archaeology, anthropology, and related fields have similarly transitioned to BCE/CE. International scholarly journals predominantly use BCE/CE, facilitating clearer communication among researchers from diverse cultural and religious backgrounds. Museums and cultural institutions have increasingly updated their displays and publications to use BCE/CE terminology.

Historical Examples Using BCE and CE

The Fall of the Roman Empire occurred in 476 CE (equivalent to 476 AD). The construction of the Great Pyramid at Giza is estimated at 2560 BCE (equivalent to 2560 BC). The writing of Shakespeare's plays occurred between 1590 and 1613 CE. The invention of the printing press by Gutenberg took place around 1440 CE. Ancient Egyptian civilization flourished from approximately 3100 BCE through 30 BCE, spanning over three thousand years.

Why the Terminology Matters

While BCE and CE represent identical dates to BC and AD, the terminology change reflects a broader commitment to inclusive language in academic discourse. The shift acknowledges that the dating system itself, based on a conventionally calculated date, serves as a universal reference point rather than an exclusively Christian calendar. This terminology supports international collaboration in research and education by using more neutral language that does not emphasize religious perspectives. The change has been widely accepted as a positive step toward more inclusive scholarly practice.
