The Christians have faith that the year of Christ’s birth is one AD concerning this system of the century and one BC is the years before his birth. Now, C.E is used as an alternative to AD which stands for Common Era. The BC is abbreviated as the period before the birth of Jesus Christ.

Christian’s Faith:-

Christian believed that B.C is abbreviated as Before the birth of Jesus Christ. While A.D means the period after the birth of Jesus Christ. But many writers use CE and BCE without any concept of religion’s belief in the place of AD and BC. The CE stands for Common Era and BCE stands for Before Common Era. This interesting invention of  AD and BC was in AD 525 by Dionysius Exiguus, also mentioned in the Julian and  Gregorian calendars.
