No one changed it. It was an arbitrary guess for the date of birth of christ which turned out to be wrong when matched against other evidence
Take the BC year and add it to the AD year with present year and bc & ad
When it comes to his birth nothing changed on the time line. He was born 33 BC. However his death was when the calendar changed from BC to AD.
AD is after and BC before
bc= before christ ad= anno domini ( the year of our lord)
100 BC is a year. Right now it is 2010 AD.
Take the BC year and add it to the AD year with present year and bc & ad
Both. It was the last year of the 21st century BC, and the first year of the 21st century AD.
AD followed BC. BC stood for Before Christ, and AD after him (Anno Domini, "year of our lord").Note that this means 1 BC was immediately followed by 1 AD, with no "zero year" between them.
BC = before christ AD = Anno Domini (year of our Lord) we are in the year 2011, time before year 1 was BC time afterwards (what we live in) is AD
When it comes to his birth nothing changed on the time line. He was born 33 BC. However his death was when the calendar changed from BC to AD.
Nothing. There was no time period between BC and AD. 1 BC was followed by 1 AD. There was no year zero or any gap between BC and AD.
AD is after and BC before
BC = Before Christ. AD = Anno Domini (latin) the year of Christ's birth.
58 years are between 30 BC and AD 30. The first thing you need to remember is that there is no year 0; the year before AD 1 is 1 BC. So the years between 30 BC and AD 30 are... 29 BC, 28 BC, 27 BC, ..., 2 BC, 1 BC, AD1, AD 2, ..., AD 27, AD 28, AD 29 29 BC through 1 BC is 29 years, and AD 1 through AD 29 is 29 years. 29 years + 29 years = 58 years
bc= before christ ad= anno domini ( the year of our lord)
If you're talking about BC and AD, BC has always been refered to as Before Christ. AD has always been refered to as After Death. Both these statements are wrong. Christ Jesus was born around 4 BC and died around 37 AD. AD actually stands for the Latin phrase Anno Domini meaning "in the year of our Lord". I hope this answers your question.Ignoring the question of exactly when Christ was born, the last year BC was 1 BC and the first year AD was AD 1. There is no zero year in either system. The years just go ... 5 BC, 4 BC, 3 BC, 2 BC, 1 BC, AD 1, AD 2, AD 3, AD 4, AD 5 ...Each century AD starts on a 01 year (e.g. 1901) and ends on a 00 year (e.g. 2000), the given example was the beginning and ending of the 20th century. Each century BC starts on a 00 year and ends on a 01 year, as the years count backward.
100 BC is a year. Right now it is 2010 AD.
