Start with the Day Master
The Day Master is the reference point of the chart. It tells you which element anchors the rest of the interpretation and how support or pressure is evaluated.

How It Works
Move from birth data to a readable BaZi result
The first pass stays practical: calculate the chart, inspect the main signals, then use timing and guides when you need depth.

How To Read A BaZi Chart
Focus on four signals first
If you are new to BaZi, treat the chart output as a framework. Start with the Day Master, check the Five Elements balance, then review major combinations and timing trends.
Check Five Elements balance
Look for overrepresented or weak elements. The balance does not mean every element must be equal, but it helps you understand where the chart is concentrated.
Review Ten Gods and pillar context
Ten Gods become useful when viewed through the chart structure. Read them together with stems, branches, and combinations instead of treating them as isolated labels.
Use luck cycles as context
Luck cycles and annual timing are trend indicators. They help frame periods of support or friction, but they are not guarantees about career, love, or wealth.

Open HuangliCalculation method and sources
A BaZi method you can inspect
BaziPilot names the calendar library, calculation choices, weighting, and report structure behind its readings. Traditional schools can differ; this page explains the rules used here without presenting one interpretation as universal authority.
Algorithmic foundation
Solar terms and stems-and-branches calculations use lunar-javascript. True solar time uses geographic longitude relative to the time zone's standard meridian (about 4 minutes per degree). Hidden stems and traditional shensha follow the rule tables documented for this implementation.
- lunar-javascript for calendar arithmetic
- Longitude-based true solar time correction
- Documented hidden-stem and shensha rule tables
- Weighted Five Elements: stems 2, branches 1, primary hidden stems 1.5, residuals 0.75
Reading structure
Each reading follows a consistent structure, so you can review chart evidence before interpretation. Thresholds and weighting choices are stated explicitly rather than hidden inside confident-sounding paragraphs.
- A structured report covering chart overview, life domains, timing, and practical guidance
- Day Master strength uses a 55 / 40 threshold — published, not hidden
- Five Elements weighting (stems 2 / branches 1 / hidden stems 1.5 / residuals 0.75) is stated in the algorithm section above

BaZi basics
What is BaZi? Four Pillars and core ideas
Four Pillars
The year, month, day, and hour pillars that make up the chart and carry heavenly stems plus earthly branches.
Day Master
The heavenly stem of the day pillar. It acts as the core reference for judging support, control, output, wealth, and authority relationships.
Five Elements
Wood, Fire, Earth, Metal, and Water. Their distribution helps reveal the chart's dominant tendencies and weaker areas.
Luck Cycles
Longer-term timing periods that provide context for how the chart interacts with changing external conditions over time.
FAQ
Questions About Personal BaZi Chart Reading
1. What does a personal BaZi chart reading include?
A reading starts with the Four Pillars generated from birth date, time, and place, then relates the Day Master, Five Elements, and timing layers to that chart. The sample report shows how findings are organized and supported.
2. How is chart analysis connected to my birth chart?
The chart provides the evidence for the interpretation: its Day Master, element balance, pillar relationships, and timing layers. Sign in to save a chart and continue in the private workspace; optional passes unlock extended reading and AI Q&A.
3. What is the Day Master in BaZi?
The Day Master is the heavenly stem of the day pillar. It is the core reference point used to judge support, output, wealth, authority, and relationship patterns in the rest of the chart.
4. Why is birth time important?
Birth time affects the hour pillar and can change the structure of the chart. It also improves timing-related reading, so a more accurate hour usually produces a more useful result.
5. How should I read Five Elements balance?
Use Five Elements balance to spot concentration and weakness, not as a simplistic scorecard. The key is understanding which elements support or challenge the chart structure around the Day Master.
6. Does the calculator include 10-year luck cycles?
Yes. After signing in, the BaZi 10-year Luck Pillars (Da Yun), annual, monthly, daily, and hourly timing panels are included. Each layer has a score curve and detail panel so you can inspect a selected window.
7. What is included before I choose a pass?
You can generate and review a chart, then sign in to save it and open the basic reading. A day or year pass unlocks extended reading and pass-based AI Q&A; see pricing for the exact access period and current terms.
8. What does the basic report include, and what is paid?
The chart, Day Master, and Five Elements preview are available without sign-in. After signing in, the basic reading adds saved history, timing panels, and a concise interpretation. Extended Reading and Human Interpretation are optional purchases; the pricing page lists current prices and access terms.
9. Is this a learning tool or a chart reading tool?
It is both a calculator and a guided reading tool, but it is written with a grounded tone. The goal is to help you understand chart structure and tendencies rather than make exaggerated guarantees.
