I'm not aware of any such pkg. On the other hand, I'm not sure you need it. Do
you really need to store all the dates in the range? You could process the file
for date D, then the file for date D + 1, ..., until you have processed all the
desired files.

Conceptually the idea of an operation

function "+" (Left : in Dates.Object; Right : in Integer) return Dates.Object;

makes sense; without knowing the details of the implementation of Dates.Object I
have no idea how easy it would be. For Ada.Calendar.Time, one would simply add
Right * Ada.Calendar.Day_Duration'Last.
