Common Era refers to the time period after the birth of Jesus Christ. This era is also known as the Christian Era, Current Era, or Vulgar Era. The term Common Era is used to avoid the religious connotations associated with the term "Anno Domini" (AD) which refers to the "Year of our Lord". Another alternative term for Common Era is the secular or neutral term of "Before the Common Era" (BCE). BCE is used as an alternative to the traditional BC (Before Christ) designation. Other synonyms for Common Era include Current Era, Era Vulgaris, Common Time, Era Moderna, or New Era.
