we should set a special day: Deleba, ~:)

B.C. means before Christ and A.D. means anno domini, or in English terms, after Death, somebody would interpreter it as : the year of our Lord.

Gotquestions.com offers more information as follows:

"It is commonly thought that BC stands for "before Christ" and AD stands for "after death."

This is only half correct.

How could 1 B.C. have been "before Christ" and 1 A.D. been "after death"?

BC does stand for "before Christ."

AD actually stands for the Latin phrase "anno domini" which means "in the year of our Lord."

 

The B.C. / A.D. dating system is not taught in the Bible. It actually was not fully implemented and accepted until several centuries after Jesus' death.

Definition: 1. Abbreviation for Anno Domini - Latin for The Year Of Our Lord - used in the Gregorian Calendar to refer to the current era. A date such as 1945 A.D. literally means 'the 1945th year of our lord', the lord in question being Jesus Christ, providing a religious context and clearly distinguishing the time from an earlier era, where B.C is used instead. The use of A.D. was popularised by Bede.

Modern historical research suggests the current A.D. date is actually wrong, as Jesus was born 4-7 years earlier than the year 1 date the Gregorian Calendar works from. However, in the modern age the actual meaning of A.D. is widely forgotten or misunderstood and the term simply signifies a different era from B.C.
