Luck & annual pillars
How to Read a Luck Pillar (大运)
A luck pillar is a stem-branch pair that colours about ten years. Read it like an extra pillar added to your chart.
Luck pillars (大运) and annual pillars (流年) are the timing layer of BaZi. The natal chart describes the structure; these pillars describe which elements and Ten Gods are emphasised in each period of life.
01
Stem first
Find the Ten God of the luck stem relative to the Day Master (the calculator labels it). That theme comes forward for the period.
02
Then the branch
The branch carries the season and hidden stems. Many readers weigh the branch more in the second half of the period.
03
Balance
Does the pillar bring the elements the chart lacks or more of what it already has? See strong/weak guides.
04
Relations
Check combinations and clashes between the luck branch and natal branches, especially the month and day branch.
05
Keep it in proportion
A luck pillar modifies the natal chart; it does not replace it. Annual pillars add a finer layer within it.

Worked example
The example chart below (1990-05-18 09:30, clock time, Asia/Shanghai, female option) is computed live. In the calculator, the same input lists the luck direction, the starting age in years-months-days and every ten-year pillar with its Ten God.

Charts on this site use the published rule set: true solar time by default, the year changes at 立春 (Start of Spring), months change at the 12 节 solar terms and the day changes at 23:00. Example charts below are computed live by the same engine.
BaZi is a traditional cultural system. This page explains how the symbols are defined and read; it does not make scientific claims or predictions about your health, money or relationships.

What each Ten God brings in a period
When a luck or annual stem arrives, read it as a Ten God relative to your Day Master. The themes below are traditional associations used as a starting point, always weighed against balance.
- 比Friend (比肩)self, peers, independence and equal partners
- 劫Rob Wealth (劫财)drive, rivalry, boldness and shared risk
- 食Eating God (食神)expression, enjoyment, output and gentle creativity
- 伤Hurting Officer (伤官)bold expression, talent, critique and breaking convention
- 偏Indirect Wealth (偏财)opportunity, flexible income, trade and social reach
- 正Direct Wealth (正财)earned income, budgeting, diligence and commitments
- 七Seven Killings (七杀)pressure, challenge, discipline under stress and decisive authority
- 正Direct Officer (正官)structure, rules, reputation and responsibility
- 偏Indirect Resource (偏印)unconventional learning, intuition, specialist skills and solitude
- 正Direct Resource (正印)support, learning, credentials, care received

Key terms
| Term | Meaning |
|---|---|
| Luck pillar 大运 | ten-year pillar derived from the month pillar |
| Annual pillar 流年 | the pillar of a calendar year, changing at 立春 |
| 起运 starting age | age at which the first luck pillar begins |
| 交运 transition | the date one luck pillar hands over to the next |
| 顺/逆 direction | forward or backward stepping through the 60-cycle |
| 节 solar term | the 12 terms that start BaZi months and set luck timing |
| 岁运并临 | the annual pillar repeats the current luck pillar exactly, doubling its theme |
| 伏吟 / 反吟 | a period pillar identical to, or fully clashing with, a natal pillar |
These terms describe structure, not outcomes. A repeated or clashing pillar marks a period worth examining closely; what it means depends on whether the elements involved help or hurt the balance of the natal chart, which is why every reading starts from the Day Master and the month branch.

Practising with how to read a luck pillar
The fastest way to understand how to read a luck pillar is to look at real charts rather than memorise rules. Enter a birth date, time and city in the BaZi Calculator, then locate where how to read a luck pillar appears: in a visible stem, hidden inside a branch, in the current luck pillar or in this year's annual pillar. Note the position, because the year pillar is usually read as background and early life, the month pillar as environment and career setting, the day pillar as the self and close partner, and the hour pillar as later life and output.
- Compare two or three charts where how to read a luck pillar is prominent and two where it is absent; write down what differs in the overall balance.
- Check the month branch first: seasonal strength changes how much any factor matters.
- Use the hidden-stems and Ten Gods tables in the calculator output instead of guessing.
- Treat single factors as clues, never as verdicts; classical texts always weigh the whole chart.
- Write the luck pillar and annual pillar beside the natal chart and mark every combination or clash they form with the four natal branches.
- Re-check results around transition dates and the 立春 boundary, where off-by-one errors are most common.
Different schools describe how to read a luck pillar with slightly different emphasis. This site follows widely used conventions (solar-term months, true solar time optional, Zi hour setting configurable) and states them openly so you can compare results with a book or another calculator.

Checklist
- Confirm birth time precision; luck timing is sensitive near solar terms.
- Read the natal chart first: Day Master, season, balance.
- Find the current luck pillar and its Ten God.
- Check relations between luck, year and natal branches.
- Treat the result as a framework for reflection.
