Bazi favorable elements calculator

• 扶抑Computed here

  Support and restraint (扶抑用神)

  The default method. A weak Day Master is supported by its resource and peers; a strong one is drained by output, spent by wealth or checked by power.

  Weak 丁 Fire in winter: Wood and Fire.

• 調候Computed here

  Climate adjustment (調候用神)

  A chart born at the height of summer or the depth of winter needs cooling or warming before anything else. 《窮通寶鑑》 lists the climate need of each Day Master in each month.

  庚 Metal in a scorching 午 month: Water first.

• 通關Partly computed

  Bridging (通關用神)

  When two strong elements are locked in a controlling clash, the element between them on the generating cycle turns the fight into a flow.

  Metal against Wood: Water bridges them (Metal feeds Water, Water feeds Wood).

  Here, balanced charts favor their thinnest elements, which is often the bridge.

• 病藥Partly computed

  Disease and medicine (病藥用神)

  Find the element doing the most harm (the disease) and the one that removes it (the medicine). The classics say a chart with a clear disease and a strong medicine is the most remarkable.

  Heavy Earth burying Metal: Wood to break up the Earth.

  Here, the climate and restraint steps catch the common diseases: too hot, too cold, too strong.

• 專旺Ask a reader

  Dominant and follow structures (專旺 / 從格)

  When one element overwhelms the chart, the usual logic flips: you go with the dominant force instead of fighting it. These structures are rare and need a careful reading.

  A rootless Day Master in a sea of Wealth follows the Wealth.

  Not detected here: read about Bazi structures, or ask a reader.

• When to ask a human reader

  A rule-based calculator is a strong first pass, but it does not detect follow and dominant structures, stem combinations that transform, or a useful god that is clashed or combined away. If your chart sits near a strength boundary, or one element fills most of it, have it read in full.

  Bazi structures (格局)

The order this calculator follows

1. 1

   Score strength

   Visible stems count 1; hidden stems 1, 0.5 or 0.3 (main, middle, residual qi). The month branch counts double and the day branch 1.2×. Same element plus resource is the support share: under 45% is weak, 55% and up is strong.

2. 2

   Check the climate

   A summer month (巳午未) with 30% Fire or more is hot; a winter month (亥子丑) with 30% Water or more is cold.

3. 3

   Choose the method

   Weak: resource and peers, with the warming or cooling element first if it is one of them. Strong: cool or warm if that also drains, spends or checks; otherwise Wealth when Resource is behind the strength, Output when peers are. Balanced: climate if extreme, else the two thinnest elements.

4. 4

   Assign the five roles

   Best pick: useful god. Second pick: joyful god. Heaviest unfavorable element: taboo god. Its producer: enemy god. The rest: idle.

The climate useful god (調候用神) is the element that corrects the temperature and moisture of the birth season. It is read from the Day Master and the month branch, and in a very hot or very cold chart it outranks support and restraint.

1. 01

   Birth time

   The hour pillar is a quarter of the chart. Near a two-hour boundary, a few minutes can swap a whole pillar, and the answer with it.

2. 02

   True solar time

   Clock time is not sun time. Depending on your longitude the real solar hour can differ by 30 minutes or more, and sites that ignore it can land on the wrong hour.

3. 03

   Counting vs weighting

   Some sites count the eight visible characters; others weigh hidden stems and give the month extra force. The table below shows how far the two drift for the same chart.

4. 04

   Method

   Support and restraint, climate, structure: each school ranks them differently. A chart that is both weak and frozen can honestly get two answers.
