Accessor method for the DateTime::Locale class, which in turn offers
several class methods of specific interest. See L<DateTime::Locale>.
+=item locale_map()
+
+Returns a hash of all available locales, mapping their id to their
+full name.
+
=item loc()
Accessor method for the DateTime::Locale instance as specified by C<id>.
=item days()
Returns a list of days of the week, Sunday first. These are the actual
-days used for rendering the calendars, so depending on which attributes
-were provided to C<new()>, this list will either be abbreviations or
-full names. The default uses abbreviated day names. Returns a list in
-list context or an array ref in scalar context.
+unique day strings used for rendering calendars, so depending on which
+attributes were provided to C<new()>, this list will either be
+abbreviations or full names. The default uses abbreviated day names.
+Returns a list in list context or an array ref in scalar context.
+
+=item narrow_days()
+
+Returns a list of short day abbreviations, beginning with Sunday. The
+narrow abbreviations are not guaranteed to be unique (i.e. 'S' for both
+Sat and Sun).
+
+=item days_minmatch()
+
+Provides a hash reference containing minimal case-insensitive match
+strings for each day of the week, e.g., 'sa' for Saturday, 'm' for
+Monday, etc.
=item months()
full names or abbreviations. The default uses full names. Returns a list
in list context or an array ref in scalar context.
-=item minmatch()
+=item narrow_months()
+
+Returns a list of short month abbreviations, beginning with January. The
+narrow abbreviations are not guaranteed to be unique.
-Provides a hash reference containing minimal match strings for each
-month of the year, e.g., 'N' for November, 'Ja' for January, 'Jul' for
-July, 'Jun' for June, etc.
+=item months_minmatch()
+
+Provides a hash reference containing minimal case-insensitive match
+strings for each month of the year, e.g., 'n' for November, 'ja' for
+January, 'jul' for July, 'jun' for June, etc.
=item daynums()
-Provides a hash reference containing day of week numbers for each day
-name.
+Provides a hash reference containing day of week indices for each fully
+qualified day name as returned by days().
=item daynum($day)
-Provides the day of week number for a particular day name.
+Provides the day of week index for a particular day name.
+
+=item dayname($day)
+
+Provides the fully qualified day name for a given string or day index.
=item monthnums()
-Provides a hash reference containing month of year numbers for each
-month name.
+Provides a hash reference containing month of year indices for each
+fully qualified month name as returned by months().
=item monthnum($month)
-Provides the month of year number for a particular month name.
+Provides the month of year index for a particular month name.
+
+=item monthname($month)
+
+Provides the month name for a given string or month index.
=item minmatch_hash(@list)
-This is the method used to generate the minimal match hash referenced
-above. Given an arbitrary list, a hash reference will be returned with
-minimal match strings as keys and full names as values.

+hash referenced above. Given an arbitrary list, a hash reference will
+be returned with minimal match strings as keys and the original strings
+as values.
+
+=item lc_minmatch_hash(@list)
+
+Same as minmatch_hash, except keys are forced to lower case.
+
+=item first_day_of_week()
+
+Returns a number from 0 to 6 representing the first day of the week for
+this locale, where 0 represents Sunday.
