No no. Computers don't count. Programs count. And they start whereever 
you program them to start.
Recall that humans count from 1 because of some historic evolution. The 
introduction of zero into human arithmetic came many centuries after 
counting. And met with much initial resistance.
The origin for array indexes is also varied in its evolution. FORTRAN 
arrays are indexed starting at 1. In some languages you can specify the 
range of indexes as in  dimension a (1900:2030) if you want to use the 
year as an index and don't care about years outside the range 1900..2030.
