BaZi Calculator
Build a Four Pillars chart, then inspect your Day Master, Five Elements balance, and luck timing in one clear view.
What You Get
A chart identity layer that connects Day Master, element signals, and reading priorities.
Nine chart modules
How It Works
The first pass stays practical: calculate the chart, inspect the main signals, then use timing and guides when you need depth.
Start with date, hour, place, and gender context so timezone handling and the hour pillar stay clear.
The tool builds the chart structure and keeps the reading available in your account history.
Use the Day Master and Five Elements view before you jump into interpretation.
Continue into luck timing, Huangli, guides, wiki terms, and follow-up questions.
How To Read A BaZi Chart
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.
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.
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.
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.
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.
Why Free BaZi

Open HuangliHow we calculate
Free BaZi is built on auditable libraries, published thresholds and disclosed limitations.
Solar terms, stems & branches and Najia derive from lunar-javascript. True solar time uses geographic longitude vs. the standard meridian (~4 minutes per degree). Hidden stems and 30+ shensha (Tianyi Guiren, Jiangxing, Wenchang, Taohua, Yima, …) follow published Ziping-pai tables.
Every reading uses a fixed set of sections, so you read structure first and interpretation second. Thresholds and weighting choices are stated explicitly rather than hidden inside confident-sounding paragraphs.
What's free, what's paid
We keep the boundary explicit so you know exactly what you'll see after signing in.

Quick Glossary
The year, month, day, and hour pillars that make up the chart and carry heavenly stems plus earthly branches.
The heavenly stem of the day pillar. It acts as the core reference for judging support, control, output, wealth, and authority relationships.
Wood, Fire, Earth, Metal, and Water. Their distribution helps reveal the chart's dominant tendencies and weaker areas.
Longer-term timing periods that provide context for how the chart interacts with changing external conditions over time.

FAQ
A BaZi calculator converts your birth date, time, and place into a Four Pillars chart. It helps you inspect your Day Master, Five Elements balance, and timing structure before doing deeper interpretation.
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.
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.
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.
No. After signing in, the decade, annual, monthly, daily, and hourly luck panels are all included. Each layer ships with a score curve and detail panel so you can drill into any window.
AI follow-up questions on your reading are free for now. Usage may become metered in the future, so we describe it as a current courtesy rather than a long-term guarantee.
The basic reading is free after sign-in: it covers the Four Pillars chart, Day Master, Five Elements summary, the luck timeline panels, and a concise interpretation. Extended Reading and Human Interpretation are optional one-time purchases.
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.
