BC: Before Christ. Used for years before the birth of Jesus Christ
AD: Anno Domini. Used for years in the reign of the christ. The current year, for instance, is really 2013 AD
Anno Domini (abbreviated as AD or A.D., sometimes found in the form Anno Domine) and Before Christ (abbreviated as BC or B.C.) are designations used to label or numbers ears in the Julian and Gregorina Calendars. The BC/AD dating system was devised by medieval monks and based on an estimate of Jesus's birth year. This estimate has later proven to be off by about six years. The more recent BCE/CE dating system ("Before the Current Era" and "Current Era," respectively) is simply the BC/AD dating system relabeled to remove religious references.
BC stands for before christ, since not many people are Christians, people do not like it that it mentions Christ, ad is also something related to god, but I don't remember
Assuming you know what AD and BC stand for, The objection is because these acronyms acknowledge Jesus and refer to him as lord (domini) and messiah/anointed (Christ).
According to Wikipedia, there is no year "0" ("Zero"). So the dateline would look like the following: ..., 4 BC, 3 BC, 2 BC, 1 BC, 1 AD, 2 AD, 3 AD, 4 BC, ... "BC" stands for "Before Christ" "AD" stands for "Anno Domini" which is Medieval Latin, translated as "In the year of the Lord", it does not stand for "After Death". The Anno Domini dating system was devised in 525 AD by Dionysius Exiguus.
In the Roman numeral system, lv stands for 55, as l = 50 and v - 5. The BC is a relatively modern addition to the dating system and stands for "before Christ" The expression "roman times" tends to refer to the days of the Roman Empire. And as the use of BC/AD was not introduced until AD 525, they would not have written lv bc.
AD stands for Anno Domini and is the dating system used after the birth of Christ in the year 0. All years before that are known as BC or Before Christ. An example is 2016 AD, which is the year we are currently in and every year since the year 0 is an AD year.
The beginning of the year AD 1 immediately followed the end of the year 1 BC. However at that time the BC/AD dating system did not exist, by the Roman calendar in use at the time 1 BC was the year 753 and AD 1 was the year 754. The BC/AD dating system was devised in AD 525, but was not widely used until after AD 800. As originally intended Jesus Christ was supposed to have been born sometime in the year AD 1, but due to misconceptions and unreliable information on the time period (not surprising as his family was insignificant common people of whom official secular records were not kept and all Jewish Temple genealogical records had been burned by the Romans in AD 70), modern calculations estimate that Jesus Christ must have been born in 4 BC or earlier.
The last date of BC was 1 BC, then the first date of AD was 1 AD, there was no zero.
Okay Will AD is older than BC because AD is very old not like BC
According to the Christian dating system we say BC which means before Christ and we refer to the time before his birth. The period after the birth 9of christ is marked with AD which means anno domini (in the year of God).
BC : before Christ AD : anno domino
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
