As a type?

   subtype Period is Date
     with Dynamic_Predicate => Begin_Date <= Period and Period <= End_Date;

As an object?

      type Dates is array (Positive range <>) of Date;
      Period : constant Dates := (Begin_Date,
                                  Begin_Date + 1 * Days,
                                  Begin_Date + 2 * Days,
                                  ...
                                  End_Date);

As an iterator?
