If only mathematicians could become zero-based.
That causes a lot of problems with number lines that do not have a zero. E.g. years go directly from -1 to +1; there never was a year zero. The elevator in our office building goes directly from floor 1 to floor -1. (To ease our minds, we have declared that the building does have a floor zero, but it is virtual, and the elevator is not built to stop at virtual locations.)

My wish is that we go back to the days of Pascal. If your array indexes run from 1950 to 2050, that is perfectly fine! If they run from 0 to 99, or from 1 to 100 - both are perfectly fine. Just tell what you want, and the compiler takes care of offsetting the index you are using in your program so that the element at the lowest index runs from the base memory address of the array. Compilers are quite good at doing that sort of calculations Smile | :) - it is a pity that the C group of languages forces us to do this sort of offsetting in application code.

Some hardware helps with trivialities: I once worked on a machine providing an instruction called MIX3: It decremented the value in the accumulator by 1, then multiplied it by 3. This was in the Fortran days: Fortran arrays are 1-based, and this 16-bit mini, adressing 16 bit words rather than bytes, used a 48-bit (3 word) float format. So MIX3 converted a "logical" (1-based) Fortran array index into a word offset from the (0-based) memory base address.

Handling discontinous number series, such as years around the start of our "Common Era", will always require special handling, though.
