What's the meaning of BCE
Common Era
Before the Common Era
Common Era or Current Era (CE)[1]  is one of the notation systems for the world's most widely used calendar era. BCE (Before the Common Era/Before the Current Era) is the era before CE. BCE and CE are alternatives to the Dionysian AD and BC system. The Dionysian era distinguishes eras using AD (anno Domini, "[the] year of [the] Lord")[2] and BC ("before Christ"). Since the two notation systems are numerically equivalent, "2019 CE" corresponds to "AD 2019" and "400 BCE" corresponds to "400 BC".[2][3][4][lower-alpha 1] Both notations refer to the Gregorian calendar (and its predecessor, the Julian calendar). The year-numbering system utilized by the Gregorian calendar is used throughout the world today, and is an international standard for civil calendars.[5]
