Precision comes from implementing the complete 60-year cycle of the Chinese calendar, not just 12 animal types.
Each year combines an animal (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig) with an element (Wood, Fire, Earth, Metal, Water).
This creates 60 unique combinations that repeat every 60 years.
Traditional astrologers consider this system for personality analysis, business decisions, and relationship compatibility.
Our API validates calculations against historical Chinese almanacs for cultural authenticity.
