The problem was religious - nobody was going to have Christ born in the
year zero.

I do belive mathematicians have done a fair bit of work on counting,
and that they are entitled to deference in this particular case.

It follows rather trivially from the fact that there were no
year zero, that the first century must contain the years [1...100] in
order to be a century.

Proof by induction will then lead you to the fact that century
number N contains the years [N*100-99, N*100]

Consequently the 20th century must be the years [1901...2000]

Q.E.D.
