Your objection has the merit of being unique and unprecedented.

But the question was: how many years elapse between -5-1-1 and 6-1-1? That question is not answered by counting the number of integers in the set {-5, ..., 6}.

Apparently you regard each of the numbers in the set as representing a year within the elapsed period, thus 12 years instead of the correct 11, from which you conclude erroneously that 0 must not be counted. The period from 1st January 6 B.C. to 1st January 6 A.D. does not include the year 6 A.D.

The basic thing to realize is that the astronomical year-numbering system begins with the integers ..., -2, -1, 0, 1, 2, ... as an abstract model, and associates each year with an integer in this sequence.

I hope this clarifies the matter for you.
