Zodiac animals change based on the Lunar New Year. Those born in January-February may have different zodiac animals depending on whether it's before or after the Lunar New Year.
The 12 zodiac animals repeat in a 12-year cycle, with each animal having unique characteristics and symbolism.
Zodiac animals go beyond simple birth year classification and are part of traditional culture used to predict personality and fortune.
