Free BaZi Calculator – Generate Your Four Pillars Chart Instantly
Accurate BaZi (八字) chart calculation with true solar time, Five Elements balance, and AI-powered interpretation.
AI will analyze your BaZi structure, personality traits, and future trends
What Is a BaZi Calculator and How Does It Work?
A BaZi calculator is an online tool that generates your BaZi (Four Pillars of Destiny) chart based on your birth date, time, and location. Unlike simple calculators, BaZi Lab adjusts your chart using true solar time and analyzes the balance of the Five Elements, Ten Gods, and luck cycles to provide meaningful insights into your life. Our system combines traditional Chinese metaphysical wisdom with modern AI technology to ensure you receive accurate and easily understandable analysis results.
Two details decide whether a chart is trustworthy. The first is time: your birth longitude and the seasonal equation of time can pull clock time and solar time more than fifteen minutes apart — enough to move your birth into a different two-hour branch. Our true solar time calculator explains the correction in full. The second is reading the chart: once the four pillars are drawn, what actually carries meaning is how the Ten Gods relate to your Day Master. New to BaZi?

What You Get When You Calculate Your Chart
Enter your birth date, time and place above. The result page then shows all of the following, free and without an account:
- Your Four Pillars chart — The heavenly stem and earthly branch of the year, month, day and hour pillars, with hidden stems, Na Yin and your Day Master. Years change at the Start of Spring and months at solar terms, not at Chinese New Year or on the first of the month.
- True solar time correction — Your birth time is corrected for the longitude of your birthplace and the legal time zone in force there on that day, including historical daylight saving. The hour pillar uses the corrected time.
- Five Elements and Ten Gods — How much of each element your chart holds, which one runs strong or weak, and which of the Ten Gods each stem represents for your Day Master.
- 10-year luck pillars and a life trajectory chart — The sequence of ten-year luck pillars and a year-by-year curve from age 1 to 96. It is calculated, not generated, so the same chart always gives the same result.
- A plain-language reading — A profile of your Day Master, whether it is strong or weak, the luck pillar you are in now and the high points of the next ten years, written without jargon.
New to BaZi? The Four Pillars of Destiny guide explains what each pillar governs, the luck pillars page plots your ten-year cycles as a curve, and BaZi Agent answers questions about your own chart in plain language.

Frequently Asked Questions
Common questions about BaZi charts and analysis
What is a BaZi chart?
A BaZi chart, or Four Pillars of Destiny, is a Chinese astrological map derived from your birth date and time. It consists of four pillars (Year, Month, Day, and Hour), each containing Heavenly Stems and Earthly Branches that reveal the flow of Five Elements energy and its influence on your life.
How accurate is a BaZi calculator?
BaZi Lab's calculator uses true solar time adjustment to ensure the highest precision. While the calculation is mathematically precise based on astronomical data, the interpretation is a tool for self-awareness. Your free will and actions play a crucial role in shaping your destiny.
Why does birth location matter in BaZi?
Your birth location determines your True Solar Time. Because of the Earth's rotation, the position of the sun varies by location even at the same clock time. Adjusting for longitude is essential for generating an accurate chart, especially for the Hour Pillar.
Is this BaZi calculator really free?
Yes, our core BaZi charting tool is completely free. You can generate your chart, view your Four Pillars, and see your Five Elements balance as many times as you like. We offer premium in-depth reports for those who want deeper analysis, but the calculator itself is free to use.
What are the Ten Gods in my chart?
The Ten Gods — Equal Companion, Competitive Peer, Eating God, Hurting Officer, Direct and Indirect Wealth, Direct Officer, Seven Killings, and Direct and Indirect Resource — describe how each stem in your chart relates to your Day Master. They map onto self-expression, wealth, authority, and learning. Your chart result labels them for you.
Why do different BaZi calculators give different charts?
BaZi, also written Ba Zi and known as the Four Pillars of Destiny, follows one method, but charts often differ in four places. The year starts at the Start of Spring, around 4 February, not at Chinese New Year. Each month starts at a solar term, not on the 1st of a calendar month. The hour pillar depends on true solar time: we correct your birth time for your birthplace's longitude and the legal time zone in force there on that day, including historical daylight saving. For births between 23:00 and midnight, some schools already use the next day's day pillar; we keep the calendar day and take the hour stem from the next day, the “late Zi hour” convention. If two charts disagree, check these four points first.
What does a free account add?
Nothing on the result page needs one: the chart, Five Elements balance, Ten Gods, ten-year luck pillars, the life trajectory chart from age 1 to 96 and the plain-language reading of your Day Master are all open. A free account saves your charts, opens a free personality summary and gives you more questions to BaZi Agent each day. In-depth reports on career, relationships and yearly fortune use credits.
What if I don't know my birth time?
Tick “I don't know my birth hour” in the form. The chart is then calculated for 12:00 noon and the hour pillar is marked as estimated. The year, month and day pillars come from the birth date, so they stay reliable (only births close to midnight can shift the day pillar). The hour pillar changes every two hours, so treat conclusions that rest on it, traditionally children and later life, as tentative.
