How Does B.C. and A.D. Work on a Timeline?

Can you understand the dates on this timeline? How come the dates on the timeline get smaller as you read left to right, but then switch and begin to grow larger?

That is very strange. Watch the video clip below to make sense of the dates.


 


What does B.C. stand for? What about A.D.?

Can you put these dates in chronological order from oldest to newest?

600 A.D.
200 B.C.
2015 A.D.
1000 B.C.
50 B.C.
