Although this seems to be a widely recognized "problem," I would argue it is 
an entirely specious one.  It makes no more sense to recognize a "year 0" than 
it would worry about the lack of a "zeroth" inch or We name centuries and 
decades without issues.   in smaller time intervals with no problem.  The 
entire concern comes down to naming issue.  Whenever a fraction from the first 
inch on a ruler is named, it is written as 0.* or */** - with either a 
preceding 0, or as a common fraction written without any preceding whole 
number.  Every year in the 19th century starts with "18" yet few people are 
confused.  Why has this ever been regarded as an issue?
