Arr[0] is the first element of an array, not the “zeroth”.

  But Arr could be empty or uninitialised...

  In a zero based array type language. In pascal I believe arrays can start where you want them to as in "array[-10..10] of integer". It's been a while though. There is no year zero. Trying to compute with one is almost certainly an error. Trying to work with it is like dividing by zero - it does not make sense. The year "1" was originally a Julian Date. Using a Gregorian Date before the calendar was introduced is almost certainly an error. For ancient things, use Before Present, where I believe Present is defined to be sometime in 1950 or there about. For "modern" things (varying definitions of modern) use a sensible format/calendar that works in your database.

    > Using a Gregorian Date before the calendar was introduced is almost certainly an error. It's just an extrapolation; using the calendar being used at the considered time would be meaningless for us, e.g. the short-lived french republican calendar [1].
