What is the meaning of B.C. and A.D. and why we use it?
B.C.=Before Christ


A.D.=After Death
Reply:Basically, you've got it. The cross-over point is the birth of Christ, BC= Before Christ, AD=Anno Domini (Year of our Lord). There was no year 0 (although I've had a professor of math try to tell me there has to be because if you look at any number-line, there's always a 0 between -1 and +1). Technically, there wouldn't have been a 1BC AND a 1AD (unless Christ was born midnight December 31), since the same year would've been partially both.





The current preferred terminology is BCE (Before Christian Era) and CE (Christian Era) to recognise the fact that when historians originally dated the birth of Christ, they got it wrong and Christ was actually born in the year "called" 5BC. But clearly Christ can't be born before He was born and equally clearly we can't redate every book, every document, every medical and legal record, etc. so BCE/CE was chosen as a means of indicating "we know the calendar is out by 5 years and the actual date is 2012 but we're going to keep on using the current numbering system".
Reply:A.D means anno domini which is a year in the christian era and B.C means before christ
Reply:It used to be Before Christ and Anno Domino which is Latin for, I think, the year of our Lord. It seems to me people are now saying Before the Common era for B.C. I guess it's PC to use that now.
Reply:BC stands for "Before Christ". AD stands for "Anno Domini", which is Latin for "In the year of our Lord". They're Chrisitan references using the birth of Christ as the reference point. Some people are now using "BCE" (Before Common Era) and "CE" (Common Era) instead.
Reply:In Catholic terms...


A.D = After Death


B.C = Before Christ


but..


In more Modern terms..


B.C.E = Before Common Era


C.E = Common Era
Reply:Actually, now we use B.C.E and C.E. Before Common Era and Common Era. That's because AD means ano domine (in the year of our Lord) but not everyone believes in Christ as being Lord and Savior. So, now we use less religious words.
Reply:yes we are in 2007 AD. and b.c means before christ and a.d means after the death of christ.
Reply:B.C.-Before Christ


A.D.- Anno Domini (the Year of of Our Lord-birth of Christ)


We use it to describe timeframes and give a reference point to time. A.D. does not refer to the death of Christ.
Reply:0BC was the year christ died. then it was 1 AD,





12bc 11bc 10bc.....0......10AD 11ad 12ad





and so on.
Reply:Anno Domini (Latin : "In the year of (Our) Lord"), abbreviated as AD or A.D., defines an epoch based on the traditionally reckoned year of the conception or birth of Jesus of Nazareth. AD is also an abbreviation for Christian Era. Similarly, Before Christ (from the Ancient Greek "Christos" or "Anointed One", referring to Jesus), abbreviated as BC or B.C., is used in the English language to denote years before the start of this epoch.





The designation is used to number years in the Christian Era, conventionally used with the Julian and Gregorian calendars. More fully, years may be also specified as Anno Domini Nostri Iesu (Jesu) Christi ("In the Year of Our Lord Jesus Christ"). 'Anno Domini' dating was first calculated in 525 and began to be adopted in Western Europe during the 8th century.





The numbering of years per the Christian era is currently dominant in many places around the world, in both commercial and scientific use. For decades, it has been the global standard, recognized by international institutions such as the United Nations and the Universal Postal Union. This is due to the prevalence of Christianity in the Western world, the great influence of the Western world on science, technology and commerce, as well as the fact that the solar Gregorian calendar has, for a long time, been considered to be astronomically correct
Reply:AD stands for the year Christ was born in, not after he died.





Its short for Anno Domini, meaning "In the year of our Lord"
Reply:BC means before Christ AD stands for anno Domini and was used after Christ died.
