Since the outbreak canonically occurs on September 20th, 2012, does this mean the current year is somewhere in 2013?

I was thinking about that. While we don't necessarily have to adhere to TWD canon, it probably doesn't make much of a difference to set it in 2013 vs any other year between then and now. For the sake of character history, we'll just adhere to the canon comic timeline as it's later than the TV series year.

(So, about March 2014 if we add the 18 months)
