Difference Between BC and AD

What is BC?

Before Christ (BC) is a way of defining a date in terms of the Christian era. Before Christ was the time when the events occurred that we refer to as history, or more precisely, human history. Before Christ is also a term used to refer to what Christians believe was the period of time before the incarnation of Jesus Christ.

When we use Before Christ in our everyday speech, we are referring to something that happened before Jesus’ birth on December 25th. For example, Jesus was baptized by John the Baptist (Matthew 3:13). This took place before Christ and hence it is said that Jesus was baptized in “the days of John”.

Christians base their dating system on the Incarnation of Jesus Christ, which they call Anno Domini or AD for short. In Anno Domini or AD, years are numbered from one until 999. The first year would be 1 AD and each year thereafter would be identified by its number alone, i.e., 1 AD 2 AD 3 AD etc..
