      subroutine ESMF_CalendarInitialize(keywordEnforcer, calkindflag, rc)

! !ARGUMENTS:
      type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below
      type(ESMF_CalKind_Flag), intent(in),  optional :: calkindflag
      integer,                 intent(out), optional :: rc

! !DESCRIPTION:
!     Initializes the default {\tt calendar} to the given type.  Subsequent

!     \begin{description}
!     \item[{[calkindflag]}]
!          The calendar kind to initialize the default to.  If not specified,
!          the default is set to {\tt ESMF\_CALKIND\_NOCALENDAR}.
