Some reverse the decade direction and every later ten-year palace is wrong; remembering the one rule keeps it straight.
What This Question Is Really Asking
The question is why some go forward and some backward. It depends on two conditions: whether the birth stem is yin or yang and the sex; combining them sets the direction, with the element phase setting the start age.
The Underlying Logic
Yang-stem males and yin-stem females go forward clockwise toward Siblings and Spouse.
Yin-stem males and yang-stem females go backward counterclockwise toward Parents and Karma.
The start age follows the element phase: water two, wood three, metal four, earth five, fire six.
Each decade spans ten years in one palace; a wrong direction skews the whole limit map, so verify before reading.
A Step-by-Step Way to Read It
- First confirm whether the birth stem is yin or yang
- Then confirm sex and set the direction
- Forward goes clockwise from Life and backward counterclockwise
- Use the element phase for the start age
- Place the ten-year decades palace by palace with ages
- Verify against past events that direction and ages are correct
Three Common Mistakes
Mistake 1: Using only sex or only stem to set direction
Mistake 2: Reversing forward and backward while reading the decades
Mistake 3: Ignoring the element-phase start age so ages are all off
Back to Your Own Chart
Decade direction is the skeleton of the limit map: stem yin-yang with sex sets forward or backward, and the element phase sets the start age. With this correct, the ten-year palaces hold.
Reading Order
- Cast the natal chart first and locate the palaces and major stars tied to determining the forward and backward direction of decades before judging anything
- Open the triple-direction of those palaces and count the auspicious, malefic and assistant stars separately
- Check where the natal Four Transformations land to set the chart's baseline tone
- Read the decade-limit transformations to see whether the determining the forward and backward direction of decades line is activated in this stage
- Then read the annual transformations and the year's palace to pin down this year's trigger and timing
- Layer natal, decade and year before concluding, then decide how to act rather than labeling good or bad
