What can be read: fixed-rule reflections
Life (命宮): Here the question is self-positioning and response style, not a personality diagnosis.
Traditionally, Tian Fu in the Life Palace suggests stewardship, steadiness and a wish for security, with stability sometimes becoming inertia. The star is strong here, so its qualities tend to show more easily.
Traditionally, Wu Qu in the Life Palace suggests practicality, directness and execution, with care sometimes expressed more through actions than words. The star is strong here, so its qualities tend to show more easily.
Wu Qu (武曲) Quan · agency (化權): Quan highlights initiative and responsibility. Check that authority matches duties; it does not promise status.

Birth-year transformations use text and color, not good/bad scores. Brightness labels come from a fixed table and are not ratings.
Nominal age: one in the birth lunar year, increasing at lunar New Year. The first decadal starts at the element-class number. These periods do not align directly with BaZi luck cycles.

Relationships, skills, resources and circumstances change. Use these prompts to review choices; natal charts and decadals are not yearly event predictions.
Reproducible rules are not scientific proof of life predictions. A single star cannot determine profession, income, marriage dates, illness or lifespan. This layer does not interpret annual transits, flying stars or unverified patterns. Empty palaces receive no invented stars; co-located major stars must be considered together. Changed data or rules may change a chart; historical snapshots keep their versions.

Heaven chart with the pinned placement rules. Year boundary: lunar New Year. Leap month days 1–15 use the current month; day 16 onward uses the next. Late Zi from 23:00 advances the whole calendar day; early Zi does not. IANA zones resolve original civil time. Nonexistent DST times are rejected; repeated times require an explicit choice. To compare charts, check original clock/zone, solar correction, day boundary, leap month and rule versions.
Zi Wei Dou Shu is also written Ziwei, Tzu Wei Dou Shu or ZWDS, and is often called Purple Star Astrology.

Schools differ slightly on this table, most often for the Geng and Ren years. This calculator uses the table below, so its charts always match it; if another tool disagrees, compare the tables first.
Provide Gregorian or lunar date, leap-month flag, sex, birthplace timezone and birth time. True solar time also needs coordinates. Sex is used only for placement/direction rules.
Date and calendar can be checked, but life/body palaces, star positions and ten-year periods need a birth hour. We do not assume noon, generate a unique chart, call AI or charge credits.
Select lunar and enter the recorded date with its leap flag. We retain both original lunar and converted Gregorian dates. Do not manually shift the month for the half-leap rule.

To compare charts, check original clock/zone, solar correction, day boundary, leap month and rule versions.
Compare time, zone, solar correction, year/day boundaries, leap-month rules and transformation tables, then find the first differing fact ID. Agreement does not establish predictive accuracy.
An empty palace has no major star but may contain auxiliary stars. Birth-year Lu, Quan, Ke and Ji mark themes, not four luck scores.
