What is annual flow?
Annual flow (liú nián) refers to the Heavenly Stem and Earthly Branch combination for each calendar year. The year 2024 is Jia Wood-Chen Dragon, 2025 is Yi Wood-Si Snake, and 2026 is Bing Fire-Wu Horse—these stem-branch pairs are the annual flow for those years. The stems and branches advance sequentially according to the sixty-year cycle, rotating every sixty years. Annual flow represents the "one-year" layer in the dynamic analysis of the Four Pillars. Together with the native's life configuration and Major Life Cycle, it forms the three-tier temporal structure of fate analysis: the life configuration is the innate foundation (unchanged for life), the Major Life Cycle is the ten-year period (changing every decade), and annual flow is the one-year period (changing annually).
Annual flow itself carries no independent auspicious or inauspicious quality. Its meaning emerges only when superimposed onto the life configuration and Major Life Cycle. Once the two characters of a given annual flow enter the life configuration, they interact with the original eight characters of the configuration and the two characters of the current Major Life Cycle through generation and restriction, combination and clash, punishment and assembly, or piercing and harm. These interactions determine the energy configuration and event tendencies for that year. The so-called "timing of manifestation" appears precisely at these key points of interaction among the three layers.
How to find your annual flow
Each calendar year has a fixed annual flow stem-branch pair—this does not vary by individual. To see the specific meaning of an annual flow for your personal life configuration, follow these steps:
- Identify the current year's annual flow stem-branch: 2024 is Jia Wood-Chen Dragon, 2025 is Yi Wood-Si Snake, 2026 is Bing Fire-Wu Horse, and so on in sequence.
- Label the annual flow's yin-yang, Five Elements, and Ten Gods: Determine what Ten Gods role the annual flow plays relative to your Day Master for that year—whether it is Wealth, Authority, Resource, Output, or Peer stars.
- Compare with the life configuration: Check if the annual flow stem-branch has a relationship of combination, clash, punishment, assembly, or piercing/harm with any of the eight characters in the life configuration.
- Compare with the Major Life Cycle: Examine the coordination between the stem-branch of the current Major Life Cycle and the annual flow—when the Major Life Cycle and annual flow share the same energy, it is a year of accomplishment; when they conflict, it is a year of obstacles.
- Synthesize the interpretation: Combine the role (Useful God or unfavorable god) of the character activated in the life configuration to determine the basic energy tendency for that year.

Types and key features of annual flow
Based on their interaction with the life configuration, annual flows can be categorized into several typical situations.
Combination-type annual flow
The annual flow stem-branch forms a combination with a stem-branch in the life configuration—either Heavenly Stem combinations (the five pairs: Jia-Ji, Yi-Geng, Bing-Xin, Ding-Ren, Wu-Gui) or Earthly Branch combinations (the six pairs, triple combinations, or triple assemblies). Combination signifies cohesion and relationships—it can indicate marriage, partnership, reunion; it can also indicate entanglement or difficulty breaking free. The specific auspicious or inauspicious outcome depends on whether the combination transforms into a new Element and whether that transformed Element is favorable or unfavorable.
Clash-type annual flow
The annual flow stem-branch forms a clash with a stem-branch in the life configuration—either Heavenly Stem restriction (Jia-Geng, Yi-Xin, Bing-Ren, Ding-Gui) or Earthly Branch six clashes (Zi-Wu, Chou-Wei, Yin-Shen, Mao-You, Chen-Xu, Si-Hai). Clash signifies change and separation—changing jobs, moving residence, or loosening of relationships. Clashing open an unfavorable god brings benefit; clashing through a Useful God brings harm. The "birth year" in the life configuration—where the annual flow Earthly Branch is the same as the year branch—is popularly called "offending the Year Branch." In practice, this refers to the complex situation where the annual flow clashes with the opposite palace of the birth year branch (i.e., the combination or clash between the annual flow and the birth year).
Punishment, harm, and piercing-type annual flow
Punishment (the three punishments: Yin-Si-Shen, Chou-Xu-Wei, Zi-Mao, and self-punishment among Chen, Wu, You, Hai) indicates internal entanglement and hidden pressure. Harm (the six harms: Zi-Wei, Chou-Wu, Yin-Si, Mao-Chen, Shen-Hai, You-Xu) indicates hidden interpersonal interference. Piercing (another term for harm) indicates hidden damage. These types of annual flow effects are less direct than combination or clash, but their wear on specific palaces may be more prolonged.
Generation and restriction-type annual flow
The annual flow stem-branch does not form combination, clash, punishment, or harm with the life configuration, acting only through Five Elements generation and restriction on the Day Master and Ten Gods. This is the most common annual flow situation. If the annual flow represents the favorable Element for the Day Master, it brings enhancement; if it represents the unfavorable Element, it brings difficulty. The annual flow's generation or restriction of a specific character in the life configuration directly alters that character's strength.
How annual flow shapes personality, career, and relationships
Annual flow is the most "concrete" temporal variable—the tangible feeling that "a certain year was good" or "a certain year was difficult" often relates to the specific energy activated by the annual flow.
For career
Years where the annual flow stem-branch activates the areas corresponding to Authority stars, Wealth stars, or Output stars in the life configuration are most prone to career changes—promotion, job change, starting a business, signing contracts. When both the Major Life Cycle and annual flow activate the Useful God, it is a year for career advancement. When the Major Life Cycle favors the Useful God but the annual flow brings a clash, it indicates "obstacles within smooth progress." To assess career annual flows, one must not look only at the inherent auspiciousness of the flow, but see which Ten God it activates in the life configuration and the health of that Ten God within the entire chart.
For marriage and relationships
An annual flow whose Earthly Branch has a combination, clash, punishment, or harm relationship with the day branch (the Spouse Palace) often indicates events related to marriage—an annual flow combining with the day branch can signify warming of affection or marriage; an annual flow clashing with the day branch can signify emotional change or separation. When the annual flow activates the spouse star in the life configuration (Wealth stars for a male chart, Authority stars for a female chart), single individuals may encounter romantic opportunities, while married individuals may experience fluctuations. The specifics depend on the nature of the combination/clash and the state of the activated character.
For health
Years where the annual flow strongly restricts the Day Master and the life configuration offers no rescue pose health risks—especially in charts with a weak Day Master. An annual flow that clashes and damages the palace where a Useful God resides may also trigger health events for family members represented by that palace. Health-related interpretations carry high risk and should not be over-extrapolated—they serve as reminders, not definitive predictions.
For wealth
Years where the annual flow stem-branch enters the wealth position in the life configuration, or activates Wealth stars, are years of active financial energy. However, "active Wealth stars" does not equal "certain gain of wealth"—one must also consider whether the Day Master is strong enough to bear wealth (a strong Day Master can carry wealth), whether the Wealth stars are robbed or broken, and whether the Major Life Cycle cooperates. For those whose life configuration cannot bear wealth, a year of strong annual flow wealth may instead be a year of "seeing wealth but losing it."
Classical sources: annual flow in the canon
The life configuration is the substance, the Major Life Cycle is the function; the Major Life Cycle is the substance, the annual flow is the function.
— Traditional Zi Ping method, general principle
This layered progression of "substance and function" points to the fundamental method of temporal analysis in fate studies: when analyzing the fortune of a specific year, the life configuration is the foundation, the Major Life Cycle is the broad context, and the annual flow is the immediate action. The Major Life Cycle is the "function" relative to the life configuration, but becomes the "substance" relative to the annual flow. Interpreting the auspicious or inauspicious nature of any annual flow must always return to the layer of the Major Life Cycle and then trace back to the life configuration itself.
The Year Branch must not be offended; offending it brings calamity.
— Popular saying (to be distinguished from Zi Ping fate theory)
This widely circulated statement is often used to prove that "any annual flow clashing with the year branch must bring disaster." Rigorous fate theory does not see it this way. "Offending the Year Branch" carries no absolute inauspicious meaning in the Zi Ping method—it merely indicates a situation where the annual flow forms a clash, punishment, harm, or repetition with the year branch. Whether it brings fortune or misfortune still depends on whether the character being clashed or punished is a Useful God or an unfavorable god in the life configuration, and whether other characters in the configuration can resolve it. Equating "offending the Year Branch" with "certain calamity" is a simplification of fate terminology by folk belief.
Common misconceptions about annual flow
A common error: Viewing the auspiciousness of an annual flow in isolation—"Jia Wood-Chen Dragon is a wood year, so it's bad for those born in the Rabbit or Goat years." In fact: The meaning of an annual flow must be read in the context of the individual's life configuration and Major Life Cycle. The same Jia Wood-Chen Dragon annual flow can be a year where a Useful God finds its place for one person, and a year where an unfavorable god clashes with a palace for another—the conclusions are completely opposite. Judging annual flow solely by zodiac sign or year branch ignores the other seven characters and the current Major Life Cycle.
A common error: Simplistically equating "offending the Year Branch" with "certain disaster." In fact: Offending the Year Branch refers to the annual flow forming a specific relationship (one of clash, punishment, or harm) with the year branch. It is merely a "dynamic node" requiring attention, not an automatic ill omen. Clashing the year branch can sometimes dismantle old structures that hinder the native—it may instead be a year favorable for change. Whether it is auspicious or inauspicious still depends on the specific life configuration.
A common error: Looking only at the annual flow Earthly Branch and ignoring the Heavenly Stem. In fact: The annual flow Heavenly Stem is equally important as the Earthly Branch—the relationship between the annual flow Heavenly Stem and the Day Master, and its combinations or clashes with the stems in the life configuration, determine the primary direction of action for that year. For the Jia Wood-Chen Dragon annual flow, the Jia Wood acts completely differently for different Day Masters—for Bing Fire, it is a Resource star generating the body; for Geng Metal, it is a Wealth star being robbed; for Jia or Yi Wood, it is a Peer star assisting the body. Looking only at the Chen Earthly Branch and ignoring the Jia Heavenly Stem misses the main actor of the annual flow.

Frequently asked questions
Is annual flow the same as the Major Life Cycle?
No. The Major Life Cycle period is ten years, derived by advancing or retreating from the month pillar, and differs for each person. The annual flow period is one year, with stems and branches cycling in the sixty-year sequence, synchronized worldwide. To interpret specific life events, one must superimpose the three layers of life configuration, Major Life Cycle, and annual flow—the Major Life Cycle sets the tone, the annual flow triggers events.
What is the "Year Branch"? Is it the same as annual flow?
The term "Year Branch" has two meanings in traditional context. One is the astronomical "Jupiter"—ancient times used the Jupiter station to mark the calendar year, and the corresponding Year Branch for each year was that year's "Jupiter Lord." The other is the "Year Branch deity" in folk belief—a divine general overseeing each year, commonly called "the Year Branch of this year." When fate theory discusses "annual flow," it typically takes that year's stem-branch (e.g., Jia Wood-Chen Dragon) as the object of analysis, which is a separate matter from the folk belief in the Year Branch deity—though both involve the unit of "year."
Is it always bad if the annual flow clashes with the life configuration?
Not necessarily. The nature of a clash is the violent collision of two energies—clashing open an unfavorable god brings fortune; clashing through a Useful God brings harm. The effect of an annual flow Earthly Branch clashing with a branch in the life configuration depends on the role that clashed branch plays in the configuration. Clashing away an unfavorable god often indicates gaining from change; clashing through a Useful God indicates important resources being shaken. The popular saying "offending the Year Branch" oversimplifies this judgment.
How does annual flow indicate specific human affairs?
After the annual flow stem-branch interacts with the life configuration and Major Life Cycle, it activates a certain Ten God or palace. Activating Wealth stars primarily indicates a financial year; activating Authority stars indicates a year of reputation and position; activating Resource stars indicates a year of study, training, or matters related to elders. An annual flow clashing with the day branch easily brings changes in marriage or health; clashing with the month branch easily brings job relocation. The specific judgment is based on the status and favorability of the activated character in the life configuration.
When does the effect of an annual flow begin and end?
In rigorous fate theory, the annual flow boundary is the Start of Spring—the Yi Wood-Si Snake annual flow for 2025 begins from the Start of Spring (around February 3–4), not from New Year's Day or the Lunar New Year. If the Start of Spring has not arrived by the end of the previous year, it still belongs to the old annual flow. Some schools use the first day of the lunar month or the Lunar New Year as the starting point, but the mainstream Zi Ping method uses the Start of Spring.
See your annual flow in unMing
unMing's Four Pillars tool displays the current annual flow and the stems and branches for several future years in the "Annual Flow" section after chart calculation. It automatically determines the main activation direction of that annual flow for your life configuration—whether it enters Wealth, Authority, or Resource stars, or activates combination/clash with a specific palace. A useful starting point for observation: compare the Heavenly Stem of the current Major Life Cycle with the Heavenly Stem of the annual flow—if they share the same energy, the year proceeds smoothly; if they restrict each other, the year requires adjusting one's pace. Then see if the annual flow Earthly Branch combines or clashes with your day branch, as that is the signal closest to your personal life.
