How to check the calendar date format in R12, 'IW' or 'WW' ??

Question

Hi!
Currently we are facing any issue where the first date in 2014 is 6-Jan and remaining dates i.e; 2.3.4.5 Jan are in last week of Dec13.
I read in Oracle Forums topic first dates in Oracle are based on IW and W W format as below;
W W format - provides the week number such that January 1 is always in week 1
'IW format - is a little different in that January 1 can be week 53 of the previous year if it is a Friday, Saturday or Sunday.
But I am unsure in which format, our customers are maintaining the calendar dates in R12?? So is there any way/script find out the date format??
They are using 4/4/5 calendar type and Prof option 'BOM: Wek or Period Start Day' is set to Monday.
If this is not the right community for this discussion, please advise the right community as well.
Please update!

Hi,
Try DATE_CHECK_PLAUSIBILITY FUNCTION.
PARAMETERS : P_DATE LIKE SY-DATUM.
START-OF-SELECTION.
end-of-selection.
CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'
  EXPORTING
    DATE                      = P_DATE
  EXCEPTIONS
    PLAUSIBILITY_CHECK_FAILED = 1
    OTHERS                    = 2.
  IF SY-SUBRC <> 0.
    WRITE :/ P_DATE, ' is Invalid Date'.
  ELSE.
    WRITE :/ P_DATE, ' is a valid day'.
  ENDIF.
If you want the OO way of doing the same, you can use this.
CALL METHOD CL_RECA_DATE=>CHECK_DATE
  EXPORTING
    ID_DATE      =
EXCEPTIONS
   DATE_INVALID = 1
   others       = 2
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Internally, it calls the above function module.
