公元 Common Era
（重定向自BCE）
公元（英语：Common Era，缩写为C.E.），即公历纪元，又称西元，现今是国际社会最多国家采用的纪年标准，最初源自于欧洲等西方基督教信仰为主国家，以耶稣出生为纪年的开始，原称基督纪年（Anno Domini），现代学者及部分基于政治正确的人士为了淡化其宗教色彩而改称公元。
由于公元纪年的起点是公元1年，所以有学者认为21世纪应始于2001年，而非2000年。

Common Era 公元
（重定向自BCE）
Common Era or Current Era, abbreviated CE, is a calendar era that is often used as an alternative naming of the Anno Domini system ("in the year of the Lord"), abbreviated AD. The system uses BCE as an abbreviation for "before the Common (or Current) Era" and CE as an abbreviation for "Common Era". The CE/BCE designation uses the same numeric values as the traditional Anno Domini year-numbering system introduced by the 6th-century Christian monk Dionysius Exiguus, intending the beginning of the life of Jesus to be the reference date. Neither notation includes a year zero, and the two notations (CE/BCE and AD/BC) are numerically equivalent; thus "2016 CE" corresponds to "AD 2016", and "400 BCE" corresponds to "400 BC". The Gregorian calendar and the year-numbering system associated with it is the calendar system with most widespread use in the world today. For decades, it has been the global standard, recognized by international institutions such as the United Nations and the Universal Postal Union.
