This is not a thin horoscope page. The calculator opens the same guided birth-input flow, then creates a Four Pillars chart with Day Master, stems, branches, elements, Da Yun luck cycles, and annual fortune entry points.
Day Pillar and Day Master
Identify the core stem that represents you, your temperament, and your relationship pattern.
Start age and Da Yun
Find when your 10-year luck cycles begin and which phase currently shapes your life.
Luck year reports
Move from the long 10-year cycle into the practical opportunities and risks of a single year.
Reading paths
Start with the question you actually care about
The calculator opens the chart first, then guides users into practical BaZi reading paths instead of leaving them with raw stems and branches.

BaZi basics
A quick map of the terms you will see
BaZi gets easier once the words connect: birth time becomes four time pillars, each pillar uses a stem and branch, the Day Master anchors the reading, and elements plus luck cycles describe how the pattern changes.
Birth year / month / day / hour
Four Pillars
Your birth moment is divided into four pillars. Each pillar gives the reading one time layer: family background, environment, self, and later expression.
Gan-Zhi calendar
Heavenly Stems and Earthly Branches
Each pillar pairs one stem with one branch. These labels carry element, yin-yang, season, and hidden-stem information rather than acting as random symbols.
The stem of the day pillar
Day Master
The Day Master is the chart's reference point. Other elements are read by how they support, drain, control, or challenge this central stem.
Wood, Fire, Earth, Metal, Water
Five Elements
The elements show relationships inside the chart: what nourishes you, what you produce, what pressures you, and where balance may be missing.
10-year timing flow
Da Yun luck cycles
Da Yun does not replace the natal chart. It adds a decade-level timing layer, so the same chart can feel easier, busier, or more pressured in different periods.
Calendar boundary rules
Solar terms and true solar time
Month pillars follow solar terms, and birth hours can shift when true solar time is applied. That is why birth city and boundary times matter.

The Day Pillar explains who the chart is really about
Most users search for a BaZi calculator, but the real reading starts with the Day Master. It tells the system how to judge wealth, career, relationship, health, and timing.
Day Stem
The visible self: your basic element, temperament, and decision style.
Day Branch
The inner seat: relationship palace, emotional habits, and private needs.
Ten Gods
The role system that turns stems into career, money, partner, authority, and talent signals.
Birth hour
Birth hour changes the Hour Pillar
The Hour Pillar affects later life, children, ambition, and hidden potential. The homepage only previews the concept; the real input step remains in the guided flow.

Stem structure
Stem and element patterns make the chart readable

Wood
Growth, strategy, expansion, initiative, and planning energy.
Fire
Visibility, output, charisma, expression, and momentum.
Earth
Stability, storage, responsibility, support, and structure.
Metal
Rules, precision, execution, discipline, and judgment.
Water
Flow, learning, communication, adaptation, and intelligence.

Start age
Da Yun starts at a calculated age, not always at birth
Da Yun is the 10-year luck cycle that gives each life stage its main weather. A good report should explain where you are now, which years are worth pushing, and which years require protection.
Da Yun vs luck year
Da Yun gives the decade. Luck year gives the event window.
For pricing and product value, Da Yun is the deeper report because it explains a full life stage. Annual fortune is ideal for a specific year's choices, risks, and timing.

FAQ
Is the free BaZi reading really free?

Can I save more than one chart?
Yes. Monthly members can manage 3 chart owners, and annual members can manage up to 10 chart owners.
What is the difference between Da Yun and luck year?
Da Yun explains the 10-year life cycle. Luck year explains the specific opportunities, pressure, and timing inside one year.
Can I use the calculator if I do not know my exact birth time?
