Formula Used
Year pillar: Adjust the birth year by selected boundary. Then use (year - 4) mod 60 for the sexagenary year cycle.
Month pillar: Use approximate solar month gates. Tiger month starts near February 4. The month stem is derived from the year stem.
Day pillar: Convert the Gregorian date to a Julian day number. Then use (JDN + 49) mod 60 for the day cycle.
Hour pillar: Convert local hour to a two-hour branch. The hour stem comes from the day stem and hour branch.
Element score: Each stem adds 1 point. Each branch main element adds 1.5 points. The balance score rewards an even spread.

Chinese Astrology Birth Chart Guide
What the Chart Shows
A Chinese astrology birth chart gives a symbolic view of time. It uses cycles of heavenly stems and earthly branches. Together, they create four main pillars. These pillars are year, month, day, and hour. Each pillar has one stem and one branch. The stem shows an element and polarity. The branch shows an animal and hidden seasonal tone. The day stem is often called the day master. Many readers treat it as the core self.
Why Elements Matter
The five elements are Wood, Fire, Earth, Metal, and Water. A chart may have more of one element. It may also lack another element. This calculator counts visible stem energy and branch energy. The result is a practical element balance score. A lower element may show useful support. For example, weak Water may favor rest and research. Weak Fire may favor confidence and expression.
Using the Result Wisely
This calculator is best for learning and reflection. It can help users compare birth patterns quickly. It can also show timing themes for a selected year. The compatibility score is simple and symbolic. It should not replace real communication. A strong match still needs patience and respect. A difficult match can still grow with care. Use the chart as a mirror. Do not use it as a final rule.
Accuracy Notes
Traditional systems can use exact solar terms. Some readers adjust for true solar time. This page uses clear formulas and helpful estimates. It also supports a Chinese New Year boundary table. That helps users born near January or February. For formal destiny reading, check with a trained practitioner. For personal planning, this tool gives a clean start.
