Zi Wei Dou Shu calculator: never read one star in isolation
Zi Wei Dou Shu places stars across twelve palaces, then reads palace relationships and time periods. A single star or one-line good/bad verdict loses the context of the full chart.
The short answer
Verify the birth input and twelve-palace chart first, then read star combinations, trines/opposites and period layers. Palace-level conclusions must be reduced when birth time is uncertain.
Input and calculation
- Birth date, time and place
- Calendar, time-zone and historical-offset handling
- Twelve palaces, Life/Body palaces and star positions
- The stated star-placement and period rules
How to read the output
Begin with the palace theme, then read stars in that palace together with opposite and trine positions, and finally switch decade, year or month layers. Every explanation should point back to visible chart facts.

Frequently asked questions
Can Zi Wei be calculated without a birth time?
Palaces and star placement depend heavily on the hour. An unknown time should not produce a deceptively complete palace reading.
Does one difficult star mean something bad?
No single-star verdict is responsible. Read the palace, companion stars, trines/opposite and the selected period together.
