These values are those returned by the calendar module. Available
productions:
locale_day_names
locale_day_names_uc
locale_day_names_lc
Names for the days of the week
locale_day_abbrs
locale_day_abbrs_uc
locale_day_abbrs_lc
Short-forms (3 characters normally) for
the days of the week.
locale_month_names
locale_month_names_uc
locale_month_names_lc
Names for the months of the year
locale_month_abbrs
locale_month_abbrs_uc
locale_month_abbrs_lc
Short-forms (3 characters normally) for
the months of the year
Interpreters:
MonthNameInterpreter
DayNameInterpreter
Both offer the ability to set an index other
than the default (of 1) for the first item in
the list.
