Is it possible to enter and use dates prior to January 1,1900, in
calucaltaions in Excel 2002. Specifically trying to calculate the number of
days between two dates where one or both of the dates are prior to January 1,
1900. If so how?

You would need to use a VBA routine for this (or write some complex
string-parsing formulas).

Excel by itself does not recognize dates prior to 1900.

What is your potential date range?

John Walkenbach created an addin that allows you to work with dates before 1900.
