-        It is recommended that implementations use the locale and calendar dependent strings provided by the Common Locale Data Repository (available at <a href="https://cldr.unicode.org/">https://cldr.unicode.org/</a>), and use CLDR *"abbreviated"* strings for DateTimeFormat *"short"* strings, and CLDR *"wide"* strings for DateTimeFormat *"long"* strings.
