This abridged example shows how a Wealth Profile connects a birth chart to a way of working.
This example links earning to skills you put into practice — teaching, writing, designing or fixing things. The reading connects this to the chart’s output pattern: making something useful and communicating its value.
It describes the wealth element as neutral, so it does not treat visibility, sales, or performance as an automatic advantage. The practical takeaway is to look at how your existing skills become useful work, without treating the chart as a promise of income.
Abridged from a generated Wealth Profile example (September 2026); wording shortened for clarity. This is not a customer testimonial or your personal reading. Your reading depends on your birth chart and chosen topic.

Also called a Four Pillars of Destiny calculator or Chinese astrology chart calculator — it converts your exact birth data into a structured eight-character chart used in Chinese metaphysics for over 1,400 years.
The chart is built from the Chinese lunisolar calendar. Your birth year, month, day, and hour each map to a pair of characters: a Heavenly Stem (天干) and an Earthly Branch (地支). Together, these four pairs — eight characters total — are your "BaZi" (八字, literally "eight characters").
The central figure in your chart is your Day Master — the Heavenly Stem of your Day Pillar. It represents you: your personality, your natural tendencies, and how you relate to the other energies in your chart. Everything in BaZi analysis flows from understanding your Day Master.
A complete BaZi reading includes four natal pillars from your birth data, plus your current Da Yun luck cycle.
Your ancestral background, early environment, and outer social persona. Reflects the era and collective energy you were born into.
Your career, parents, and the dominant season of your chart. The strongest influence on your Day Master's strength and elemental balance.
You — your core personality and your primary relationships. The Day Stem is your Day Master, the single most important character in your chart.
Your children, inner thoughts, ambitions, and the later years of your life. Requires your birth time for accurate calculation.
Your 10-year luck pillars show the elemental energies cycling through your life. Timing decisions to your active Da Yun is central to BaZi.
Sample BaZi Chart — How It Looks
| Hour | Day (You) | Month | Year |
|---|---|---|---|
| 壬 Ren Yang Water | 甲 Jia — Day Master Yang Wood | 丙 Bing Yang Fire | 庚 Geng |
| 子 Zi — Rat Water | 午 Wu — Horse Fire | 寅 Yin — Tiger Wood | 午 Wu — Horse Fire |
Day Master is Jia Wood (甲). The chart is heavy in Fire and Wood, with a Water resource in the Hour. MisterGuan's AI reads the elemental balance, Ten Gods relationships, and active Da Yun to generate personalized insights.
Your Day Master is derived from your birth date. There are 10 possible Day Masters across the five elements, each with distinct personality traits.
| Element | Day Master | Character | Core Traits |
|---|---|---|---|
| Wood | Jia (Yang Wood) | 甲 | Driven, principled, ambitious — like a tall tree reaching upward |
| Wood | Yi (Yin Wood) | 乙 | Flexible, adaptable, charming — like a vine that finds its way |
| Fire | Bing (Yang Fire) | 丙 | Warm, outgoing, inspiring — like the sun, lights up every room |
| Fire | Ding (Yin Fire) | 丁 | Thoughtful, perceptive, loyal — steady and warm like candlelight |
| Earth | Wu (Yang Earth) | 戊 | Reliable, stable, protective — solid and dependable like a mountain |
| Earth | Ji (Yin Earth) | 己 | Nurturing, detail-oriented, resourceful — like fertile soil |
| Geng (Yang Metal) | 庚 | Decisive, direct, justice-oriented — sharp and clear like a sword | |
| Xin (Yin Metal) | 辛 | Refined, perfectionist, aesthetic — precise and beautiful like a jewel | |
| Water | Ren (Yang Water) | 壬 | Resourceful, strategic, free-spirited — deep and vast like the ocean |
| Water | Gui (Yin Water) | 癸 | Intuitive, empathetic, mysterious — gentle but persistent like rain |
MisterGuan's engine uses the corrected Zi Ping method — the same system used by professional practitioners.
Provide your birth date, time (if known), and location. Location is used to calculate True Solar Time — a precision adjustment that can shift your Hour Pillar by up to 30 minutes depending on where you were born.
Month pillars in BaZi change at solar terms (節氣), not the 1st of the calendar month. MisterGuan calculates exact solar term crossing times so your Month Pillar is accurate — something many calculators get wrong.
Your Year, Month, Day, and Hour Pillars are derived with their Heavenly Stems and Earthly Branches. Hidden stems (Cang Gan) — the elements concealed inside each Branch — are also extracted for a complete reading.
Your 10-year luck pillars are calculated from your birth date and gender using solar term distances. MisterGuan generates 9 Da Yun pillars covering decades of your life timing.
Once your chart is built, MisterGuan's AI reads the elemental balance, Ten Gods relationships, and active luck cycles to deliver insights on personality, career, relationships, and timing — in plain English.
The calculator is the starting point. These guides cover what the chart goes on to mean.

Common questions about BaZi calculators and how they work.
What is a BaZi calculator?
A BaZi calculator converts your birth date and time into a Chinese astrology chart. The chart shows four pillars — Year, Month, Day, and Hour — each composed of a Heavenly Stem and an Earthly Branch. These eight characters reveal your Day Master element, your personality traits, and your timing cycles over a lifetime.
What do I need to calculate my BaZi chart?
You need your birth date (year, month, day) and ideally your birth time. The birth time determines your Hour Pillar and affects your Da Yun start age. If you don't know your exact birth time, a three-pillar reading is still meaningful.
What is a Day Master in BaZi?
The Day Master is the Heavenly Stem of your Day Pillar — it represents you in your BaZi chart. There are 10 possible Day Masters (Jia Wood, Yi Wood, Bing Fire, Ding Fire, Wu Earth, Ji Earth, Geng Metal, Xin Metal, Ren Water, Gui Water). Your Day Master reveals your core personality, strengths, and how you interact with the world.
How is BaZi different from the Chinese zodiac?
The Chinese zodiac assigns one animal based solely on your birth year — shared by roughly 1 in 12 people on Earth. BaZi uses your year, month, day, and hour to produce 8 unique characters. Because it incorporates the day and hour, no two people alive today are likely to share the same complete BaZi chart.
How accurate is this BaZi calculator?
MisterGuan uses solar term boundary corrections, True Solar Time adjustments, and the corrected Zi Ping method — the same standards used by professional BaZi consultants. The chart calculation itself is mathematically precise. The AI reading interprets that chart based on classical BaZi principles.
How is the month pillar calculated?
The BaZi month is set by solar term boundaries, not calendar dates, and the month stem follows from the year stem by the Five Tigers rule. The month pillar formula guide shows the full table and a worked example.
What is a Da Yun?
A Da Yun is a ten-year luck pillar. Your chart moves through a sequence of them across your life, and each one shifts the element balance of your birth chart for about a decade. The Da Yun calculator shows your full sequence with your starting age.
What does a BaZi personality analysis include?
