It stands for Before Christ. The initials BC and AD (Anno Domini) were created after the 525 Easter as a way to divide dates as occurring before or after Christ's birth. Anno Domini Nostri Iesu (Jesu) Christi literally means 'in the year of our Lord Jesus Christ. AD refers to any year after or including the birth of Christ (They were off by a few years in their calculations). The first year AD is 1 AD, intended to be the year of Christ's birth. Preceding 1 AD is the year 1 BC. There was no 12 month period designated Year Zero.
B.C. stands for the years Before Christ. This designation was given many years after His death and the year of Christ's birth is actually estimated to be between 3 and 6 A.D.
