I wanted to know how to find your chinese zodiac sign?

Ive been curious on how to find my chinese zodiac sign but the thing is I read somewhere that if you are born after the first full moon of the month , it changes what sign you are example : I am born a metal sheep/goat but the dates are from : Feb.15,1991 to Feb.03,1992 but i am born jan 15th and the first full moon of the month is jan 3rd , so can anyone tell me what sign i am ?|||chinese zodiac sign is based on the chinese lunar calendar. The Spring Festival is the first day of the Chinese Lunar New Year. Feb.04,1992 is the first day of monkey year, so you are a Goat person.
