There is nothing than programming that solves the problem.
I recommend You read about COBOL Intrinsic Functions and date-functions.
Here is a small program example:
Code:
       Identification Division.
       Program-ID.  DAYNAME.
       Data Division.

       Working-Storage Section.
      * Change to your date
       01 TheDate        Pic 9(08) Value 20120315.
       77 TheDay         Pic 9(01) Binary.

       01 TheTable.
          05 TheDays.
             10 Pic X(09) Value 'Monday'.
             10 Pic X(09) Value 'Tuesday'.
             10 Pic X(09) Value 'Wednesday'.
             10 Pic X(09) Value 'Thursday'.
             10 Pic X(09) Value 'Friday'.
             10 Pic X(09) Value 'Saturday'.
             10 Pic X(09) Value 'Sunday'.
          02 TheDaytab Redefines TheDays.
             05 TheDayName Pic X(09) Occurs 7.

       Procedure Division.
           Compute
               TheDay =
               Function Rem(Function Integer-Of-Date(TheDate), 7)
           End-Compute
           If TheDate = 0
              Move 7 to TheDay
           End-If
           Display 'The name of the day is: ' TheDayName(TheDay)
           GoBack
           .
