Life and Body Palaces
The Life Palace describes the baseline pattern; the Body Palace shows where effort tends to become visible in daily life.

How to use the calculation
What can a Zi Wei Dou Shu chart help you analyze?
Zi Wei Dou Shu maps themes across twelve life areas. Start with the map itself, then use timing layers to ask where attention is gathering—not what fate has already decided.
02
Twelve life areas
The palaces separate work, money, relationships, family, wellbeing and movement so a broad concern becomes a clearer question.
03
Stars and transformations
These describe how a life area may be supported, made visible or pressured. One symbol is never treated as a final answer.
04
Decade and yearly focus
Timing layers help identify which area deserves attention now. They guide preparation and priorities rather than predict a fixed event.
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.
Before you calculate
Zi Wei Dou Shu calculator FAQ
What does this Zi Wei Dou Shu calculator show?
It calculates the Life Palace, Body Palace, Five Element Bureau, twelve palace roles, main stars, support stars and birth-year transformations.
Do I need an exact birth time?
Yes. The palace layout changes with the birth hour, so this calculator does not invent a chart when the birth time is unknown.
How are international birth times handled?
Enter the local time on the birth record and select the birth city. The calculator applies the city’s historical IANA time zone and asks you to resolve repeated daylight-saving times.
Is the result a prediction?
No. It is deterministic chart data. Different Zi Wei schools may use different transformation, late-hour and leap-month rules, so interpretation should remain conditional.
