/*  The Gregorian Calendar, that most countries of the world use,
    is such that it actually consists of 14 different types of
    calendars, which can be denoted with numbers from 1 to 14
    in the following way:

       1  Non-Leap Year starting with Monday
       2  Non-Leap Year starting with Tuesday
       3  Non-Leap Year starting with Wednesday
       4  Non-Leap Year starting with Thursday
       5  Non-Leap Year starting with Friday
       6  Non-Leap Year starting with Saturday
       7  Non-Leap Year starting with Sunday
       8  Leap Year starting with Monday
       9  Leap Year starting with Tuesday
      10  Leap Year starting with Wednesday
      11  Leap Year starting with Thursday
      12  Leap Year starting with Friday
      13  Leap Year starting with Saturday
      14  Leap Year starting with Sunday

   This program prints initialization data for arrays that
   represent the above calendars. 

   The output data of this program is used in ISODate.java.
