This Java code will print out a list of the locale, country name, iso3166 code, iso639-2 code, and the corresponding date formats used in that country.
import java.text.SimpleDateFormat;
import java.util.*;
import java.io.*;
import java.text.DateFormat;
// this seems to work for everything but hindi and thailand
public class LocaleDates {

Locale[] list = SimpleDateFormat.getAvailableLocales();
Map<String,List<Locale>> sortedLocales = new TreeMap<String,List<Locale>>();
for ( Locale locale : SimpleDateFormat.getAvailableLocales() ) {
if ( locale.getISO3Country() != null && locale.getISO3Country().length() != 0 ) {
List<Locale> countryLocales = sortedLocales.get(locale.getISO3Country());
if ( countryLocales == null ) {
countryLocales = new ArrayList<Locale>();
sortedLocales.put(locale.getISO3Country(), countryLocales);
}
countryLocales.add(locale);
}
}
out.println("ISO 3166 Country Code ISO639-2 Country Code Country ISO 3166 Country Code ISO639-2 Lang Language Date Format");
