Is my Chinese zodiac sign just my birth year animal?

The year animal is one branch out of eight characters. A full chart pairs a stem with a branch for the year, month, day and hour — and the day stem, the Day Master, is the one the other three are read against. Most popular Chinese astrology uses only the first of the four.

Why does my sign change around Chinese New Year?

Two boundaries are in common use and they disagree by days or weeks. Many zodiac calendars turn the animal year at Chinese New Year; Four Pillars practice turns the stem-branch year at Li Chun, the start-of-spring solar term in early February. A birth between them carries one label under each convention.

Is this a Four Pillars chart?

Yes. It shows the year, month, day and optional hour pillars, their hidden stems, and the Ten Gods relationships to the Day Master. Visible element counts and hidden-stem occurrences are shown separately.

Why does the month animal depend on my birth time?

The stem-branch months begin at solar terms, which are astronomical events with a time of day, not calendar dates. Li Chun 2021 occurred at 22:58 China Standard Time on 3 February; the chart places that instant on the selected birthplace zone's clock. A fixed offset can be entered instead.

What is the Day Master?

The stem of the day pillar. In Four Pillars it stands for the person, and every other character in the chart is read by how it relates to that one phase — whether it generates it, is generated by it, controls it, or is controlled by it.

Start with your Day Master and chart relationships

Your shown Day Master is 辛 Xin, Yin Metal. It is the day stem against which the chart names other stems. Without a birth time, a 23:00–23:59 birth may move the day pillar under this site's late-Rat convention.

Year stem 丁 Ding: Seven Killings because Fire controls the Day Master's Metal, with matching polarity.
Month stem 癸 Gui: Eating God because Water is generated by the Day Master's Metal, with matching polarity.

Visible phase balance

What this chart is made of

Each pillar carries a phase in its stem and another in its branch. The 6 visible characters below are the first layer a reading compares with the Day Master.

Hidden stems inside your chart

Your 3 calculated branches contain 8 hidden-stem occurrences. Primary, middle and residual name each stem’s place inside its branch.

Year · Snake 巳: 丙 Bing · primary · Yang Fire · Direct Officer
庚 Geng · middle · Yang Metal · Rob Wealth
戊 Wu · residual · Yang Earth · Direct Resource
Month · Ox 丑: 己 Ji · primary · Yin Earth · Indirect Resource

Day · Pig 亥: 壬 Ren · primary · Yang Water · Hurting Officer
甲 Jia · middle · Yang Wood · Direct Wealth

Wood 1 · Fire 1 · Earth 2 · Metal 2 · Water 2. These are occurrences inside branches, counted separately from the visible characters; primary, middle and residual are not equal-strength weights.

Wood appears inside the branches even though absent from the visible-character count.
