How to use the calculation
What can a BaZi chart help you analyze?
The Four Pillars are the structure, not a verdict. They become useful when you connect repeated patterns to ordinary choices about work, money, relationships and timing.
02
Ten Gods and role balance
They organize recurring roles around expression, authority, support and resources—useful for meetings, career fit and money habits.
03
Ten-year and annual cycles
They show when the surrounding demands may shift. A cycle is a planning window, not a promise that one event must happen.
04
Relationship patterns
The same structure can help frame how you approach messages, closeness, conflict and personal space without labeling a relationship as good or bad.
Why Hongsimdang compares three systems
BaZi describes the overall structure and longer cycle. Zi Wei Dou Shu narrows the life area. Western astrology adds planetary tension and timing. When several views point to the same pattern, we translate it into practical language about messages, meetings, dating, money and choices.
The free result includes the Four Pillars, Day Master, Five Element and role-balance visuals, 10-year luck cycles, and selectable annual and monthly flow. Unknown-time sections are omitted or marked as limited rather than guessed.
