For a timeline: would it go from
100 AC to 200 DC to 300 DC.
OR
would it be
100 AC to 100 DC to 200 DC?

What does AC, DC mean?

aC is the same as B.C.
and dC is the same as AD
aC means antes de Cristo in Spanish
dC means despues de Cristo 
Traditional abbreviations:
BC = before Christ  and you count down. 800 BC was 300 years earlier than 500 BC.
AD = anno domini (after Christ's birth, supposedly)  and you count up. 800 AD was 300 years later than 500 AD.
