To this: From the discussion of video games. Time of action: 0 year AD.
Don’t draw knowledge from American games and movies.
There was no 0 year A.D. and it will never be. The year ending with Christmas I.C. The first year of the new era is called "The first year before the new era", and the following year is called "The first year of the new era".
