903 * xr Use roman numerals for the next numeric format character
904 * xh Use hebrew numerals for the next numeric format character
905 * xx Literal x
906 * xg Genitive month name

908 * xij j (day number) in Iranian calendar
909 * xiF F (month name) in Iranian calendar

919 * xjY Y (full year) in Hebrew calendar

921 * xmj j (day number) in Hijri calendar
922 * xmF F (month name) in Hijri calendar
923 * xmn n (month number) in Hijri calendar
924 * xmY Y (full year) in Hijri calendar
925 *
926 * xkY Y (full year) in Thai solar calendar. Months and days are
927 * identical to the Gregorian calendar
928 * xoY Y (full year) in Minguo calendar or Juche year.
929 * Months and days are identical to the
930 * Gregorian calendar
931 * xtY Y (full year) in Japanese nengo. Months and days are
