 # Now loop for beginning qtr and ending qtr
      
      while (Date_to_Days(@x) < Date_to_Days(@y)) {
           
         my @qtr_end_date=Add_Delta_YMD(@x, 0,3,-1); 
         my $diff=Date_to_Days(@qtr_end_date)-Date_to_Days(@e_dt);
         print "DIFF $diff\n";
         if (abs($diff)<60) {
            @qtr_end_date=@e_dt;
         }

     printf("%4d-%02d-%02d\t%4d-%02d-%02d\t%sQ%01d\n",
               @x, @qtr_end_date, substr($x[0],2,2), $qtr);

       @x = Add_Delta_YMD(@x, 0,3,0);

        #  roll over quarter to 1, beyond 4
        $qtr++;
        $qtr = $qtr > 4 ? 1 : $qtr;
      }

This is tested for your two cases. I am curious why you would want output which truncates the last quarter?
