Zi Wei Dou Shu
Explore the twelve palaces of Purple Star Astrology through a simplified, repeatable board. Our version uses the civil month and day you enter as stand-ins for lunar values; it does not convert between calendars or handle leap lunar months. The result can differ substantially from a traditional lunar birth chart. Use it to learn the layout and reflect on its symbols, with the same inputs returning the same board.
The birth that builds the board
This simplified board uses your civil month and day without lunar-calendar conversion or leap-month handling. It may differ substantially from a traditional birth chart; use it as a learning and reflection exercise.
