The Korean zodiac is essentially identical to the Chinese zodiac, but the Sino-Korean word 양 ( yang ) normally refers specifically to a sheep in the Korean language (where a native Korean word 염소 yeomso is used to mean " Goat "), although the Chinese source of the loanword yang may refer to any ovicaprid. The Vietnamese zodiac is almost identical to the Chinese zodiac except the second animal is the Water Buffalo instead of the Ox , and the fourth animal is the Cat instead of the Rabbit . The Japanese zodiac includes the Sheep ( hitsuji ) instead of the Goat (which would be yagi ), and the Wild Boar ( inoshishi , i ) instead of the Pig ( buta ).  The Japanese have, since 1873, celebrated the beginning of the new year on 1 January as per the Gregorian Calendar . The Thai zodiac includes a nāga in place of the Dragon  and begins, not at Chinese New Year , but either on the first day of fifth month in Thai lunar calendar , or during the Songkran festival (now celebrated every 13–15 April), depending on the purpose of the use.
