Frequently Asked Questions

Saju is the core concept of Korean Myeongli (命理) — your birth year, month, day, and hour each yield a Heavenly Stem (天干) and an Earthly Branch (地支), producing 8 characters total. These 8 characters reveal your personality, career path, relationships, wealth flow, and health tendencies through Yin-Yang and the Five Elements.

Cheonmyeongdang processes orthodox Myeongli (Ziping Zhenquan, Qiongtong Baojian, Ditian Sui) plus astronomical solar-term calculations in under 1 second. The Manseryeok (10,000-year calendar) data is sourced from KASI (Korea Astronomy & Space Science Institute) with 0-second precision. However, fortune interpretations are for reference only — never use as the sole basis for medical, legal, or financial decisions.

24/7 free-form questions based on your 8 characters + Ten Gods + 10-year Luck Cycle data. Examples: "Is this year good for changing jobs?", "When should we try to conceive?", "Is this business loan safe?" Powered by Claude Sonnet 4.5 with a Myeongli-expert system prompt — significantly more contextually accurate than generic ChatGPT for Saju questions.
