Zi Wei Dou Shu

Zi Wei Dou Shu is an online birth-chart tool for exploring Chinese Purple Star Astrology. It combines traditional chart calculation with AI-generated explanations and a multilingual library of introductory guides.

Start by entering a birth date, birth time, and the other requested chart details. The app generates a chart organized into 12 palaces, showing the major stars associated with each life area. A brief AI reading introduces the chart, while the built-in star and palace guides help beginners understand unfamiliar terminology. Optional true solar time settings are available for people who use that chart-calculation convention.

The free offering includes chart creation and a brief AI introduction. More detailed AI readings are available as optional paid features. This distinction is useful for readers who want to explore the chart first before deciding whether to purchase a longer interpretation.

The interface supports English, Simplified Chinese, Traditional Chinese, Japanese, Korean, and Vietnamese. English-language guides introduce the system as Chinese Purple Star Astrology and explain its stars and palaces without assuming prior knowledge of Chinese terminology.

The app is intended for people interested in traditional culture, astrology symbolism, and self-reflection. Its interpretations are for entertainment and exploration; they do not provide guaranteed predictions or professional advice. Zi Wei Dou Shu is a distinct tradition with its own chart rules, rather than a direct conversion of Western astrology or a generic zodiac-sign quiz.
