Childhood Before the Luck Pillars: The Month Pillar and Minor Luck

When a child is born, the luck pillars have not started yet. They only take over in the start year: some children begin at one or two, others not until ten. For the childhood before that, the old texts used a separate "minor luck," read one year at a time. This stretch is also called the childhood limit (童限, tong xian).

Where the start age comes from

The start age is worked out from the distance between the birth date and the previous or next "jie" solar term: three days count as one year and one day as four months. A boy born in a yang year or a girl born in a yin year counts forward to the next term; a boy born in a yin year or a girl born in a yang year counts back to the previous one. So the closer the birthday is to a solar term, the earlier the luck pillars begin. See when luck pillars start.

How we counted: our engine cast one chart for every day from 1960 to 2005, with the birth hour drawn by a fixed-seed random sample and male and female charts alternating, 16,802 charts in all. Missing elements are counted from eight characters (the four stems plus each branch's main hidden stem); favorable and unfavorable elements come from our strength engine.

Minor luck is counted from the hour pillar, so it needs the birth hour; without it, childhood can only be read from the month pillar. Minor luck runs in the same direction as the luck pillars; it simply starts from the hour pillar instead.

A curious, expressive Gui Water boy

  1. Day Master: Gui Water, quiet and imaginative, a close observer.
  2. Main Ten God group: the Yin Wood year branch and the Yi Wood month stem are both Wood, which for Gui Water is Output (Water produces Wood), the heaviest of the five groups. That makes him "the curious, expressive child." Full of ideas and always asking why. Give chances to say things and make things; explaining a rule works better than issuing an order.
  3. Five elements: Wood 2, Fire 2, Earth 1, Metal 0, Water 3; missing Metal. This Gui Water is weak, and Metal, which produces Water, is exactly a favorable element, so adding a little of it makes sense.
  4. Childhood: his luck pillars only begin at age 10. Before that, minor luck starts in 2022 with Ding-Si and changes every year. The first luck pillar, Bing-Wu (Direct Wealth), begins in 2031 and its ten years run from about fourth grade to the end of high school.

How to read this stretch

Some classical writing on the childhood years speaks of "barriers" and other ominous-sounding markers. We do not use these or make that kind of verdict: there is no consistent method for finding them, and they easily give parents needless worry.

A straight word: BaZi is a mirror for understanding your child, not a script written for them

A child's character is shaped all the way along by family, school and friends. BaZi can only describe the directions they tend to grow in by nature. Used to understand why a child is the way they are, it can be a real help; used to predict what they will become, or to choose their path for them, it is being used in the wrong place. We do not cover health or medicine, and we do not make verdicts such as a child "clashing with" a parent. Everything on this site is for reference and entertainment.

What is minor luck in BaZi?

The yearly pillar that stands in for luck pillars before they begin. It counts from the hour pillar, forward for a boy in a yang year or a girl in a yin year, backward otherwise, and changes every year.

How do you read luck before a child's luck pillars begin?

Tradition uses the month pillar as the backdrop of childhood and minor luck for the rhythm of each year. But at this age the family matters far more than the chart.
