What is the Day Master?

The Day Master is the Heavenly Stem of the Day Pillar, representing your core identity in BaZi.

How are the Luck Pillars calculated?

Luck Pillars are 10-year cycles calculated using the Year Pillar, gender, and Day Master element via `calculate_luck_pillars`.

Can I analyze my elemental balance?

Yes, use `analyze_elemental_composition` with the output from the pillar calculation to see your elemental counts.

This MCP server provides deterministic calculations for the Chinese BaZi (Four Pillars of Destiny) system. It allows AI agents to derive the core eight characters from birth data, identify the Day Master, analyze the elemental distribution (Wood, Fire, Earth, Metal, Water), and project 10-year Luck Pillars. Use calculate_four_pillars to get the primary pillars, analyze_elemental_composition to check for missing elements, and calculate_luck_pillars to map life cycles.
