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 because bc started after
B.C. Stands for "Before Christ"A.D. is Latin, it stands for Anno Domini, which translates to "The Year of our Lord."They mean exactly the same thing. Whether you believe in Jesus Christ or not, AD and BC are a numbering methodology. That is, BC and AD were chosen around a specific event in a certain time - whether you believe that event happened or not, BC and AD still count from that time in history.As a side note, "BC" and "AD" are slowly being replaced, in favor of "BCE" (Before Current Era) and "CE" (Current Era).
AD
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
The 'B' in 'BC' stands for 'BEFORE'. All the years 'BC' are years "Before" something. As time 'before' something goes along, you get closer and closer to the event, so the number of years 'before' it is descending. Until finally you reach the event, and you are at the year 'ZERO' before it. The 'A' in 'AD' stands for 'AFTER'. All the years 'AD' are years "After" something. If you're counting years 'after', you start at 'zero' when the event happens. Then as time 'after' it goes along, you get farther and farther from the event, so the number of years 'after' it is ascending.
Alphabetically, AD is first; in terms of time, BC is first.
BC is the time before jesus christ was born therefore BC is BEFORE CHRIST and AD refers to the time after christ was born
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.
There was no period between BC and AD. One followed the other. After 1 BC was the year 1 AD. There was no year zero or anything else between BC and AD. BC is Before Christ. AD is Anno Domini, the time of Our Lord, so basically from when he was born. So there is no time period in between before he was born and when he was born.
AD or Anno Domini in latin means 'in the year of our lord'. 0 AD is when jesus is supposed to have died. all time before that is now known as BC and all time after is AD. BC (before christ)
So long after the AD time that there is no AD in front or after it.
