What is bc meaning?

BC stands for "Before Christ" and refers to the period of time in human history before the birth of Jesus Christ. This system of dating was widely used in Western society, particularly in historical and religious contexts, until the 20th century. It is now commonly replaced with the use of BCE (Before Common Era) to avoid religious connotations. However, BC is still often used informally and is widely recognized as a historical reference point. In chronological order, BC years count backwards from 1 AD (Anno Domini), which is the year of Jesus Christ's birth according to some historical calculations.
