896 * xr Use roman numerals for the next numeric format character
897 * xh Use hebrew numerals for the next numeric format character
898 * xx Literal x
899 * xg Genitive month name

901 * xij j (day number) in Iranian calendar
902 * xiF F (month name) in Iranian calendar
903 * xin n (month number) in Iranian calendar
904 * xiy y (two digit year) in Iranian calendar

911 * xjn n (month number) in Hebrew calendar
912 * xjY Y (full year) in Hebrew calendar

914 * xmj j (day number) in Hijri calendar
915 * xmF F (month name) in Hijri calendar
916 * xmn n (month number) in Hijri calendar
917 * xmY Y (full year) in Hijri calendar
918 *
919 * xkY Y (full year) in Thai solar calendar. Months and days are
920 * identical to the Gregorian calendar
921 * xoY Y (full year) in Minguo calendar or Juche year.
922 * Months and days are identical to the

924 * xtY Y (full year) in Japanese nengo. Months and days are
