What is BaZi?

BaZi (八字, “eight characters”) is a Chinese tradition that maps your birth moment to eight Chinese characters — one pair for the year, month, day, and hour you were born. The eight characters describe a structural pattern: how you tend to make decisions, what kinds of work environments fit you, where friction shows up, and how the pattern changes over decade-long timing cycles.

The closest Western analogues are personality models (like the Big Five or Myers-Briggs) crossed with a calendar system. Unlike those, BaZi was not derived from a questionnaire; it was derived from observation of how the date and time of birth correlate with observable patterns in life. Modern practitioners use it as a decision-making tool: timing a launch, choosing a career, picking a partner with compatible communication patterns.

What BaZi is not: a fortune-telling system, a horoscope, a predictor of specific events, or a medical diagnostic. It describes tendencies and structural patterns. The rest is up to you.

The five elements

BaZi reads everything through five elements: Wood, Fire, Earth, Metal, and Water. These are not literal materials — they are shorthand for behavioural and structural patterns.

• Wood — growth, ambition, vertical extension, principle. Wood charts tend to think long-term and build structures that compound.
• Fire — visibility, broadcast, attention, warmth. Fire charts tend to organise others around their attention and energy.
• Earth — stability, absorption, mediation, patience. Earth charts tend to be the connector and the holder of the room.
• Metal — precision, discipline, refinement, judgement. Metal charts tend to cut through ambiguity and demand quality.
• Water — adaptability, depth, intelligence, fluidity. Water charts tend to read situations carefully and adapt their approach.

The elements interact in two cycles. The generating cycle: Wood feeds Fire, Fire creates Earth, Earth births Metal, Metal condenses Water, Water grows Wood. The controlling cycle: Wood breaks Earth, Earth absorbs Water, Water extinguishes Fire, Fire melts Metal, Metal cuts Wood. Most of BaZi’s interpretive depth comes from how these two cycles play out across your eight characters.

Your Day Master

Of the eight characters in your chart, one is the most important: the upper character of the day pillar. This is your Day Master, and it represents you — your core identity, the way you naturally engage the world.

There are ten possible Day Masters, one for each combination of the five elements with two polarities (yang and yin). Yang Wood (甲) is the long-horizon Architect; Yin Wood (乙) is the adaptable Diplomat. Yang Fire (丙) is the Broadcaster; Yin Fire (丁) is the Lantern. And so on through Earth, Metal, and Water.

Everything else in the chart is read in relation to your Day Master. The other seven characters are not just standalone attributes — they are described by how they support, drain, control, or are controlled by your Day Master. This is what makes BaZi a relational framework rather than a list of traits.

A common beginner mistake is to read your Day Master as your “type” in the same way Myers-Briggs assigns one. It is not. Two people with the same Day Master can read very differently depending on the rest of their chart — which months they were born in, what supports or challenges the Day Master, and which timing cycles they are in. Use the Day Master as the starting frame, not the final label.

The full Day Masters hub has a dedicated page for each of the ten archetypes.

How to read your chart

When you generate your chart on this site, you will see eight characters arranged as four vertical pillars: Year, Month, Day, and Hour. Each pillar has an upper character (a Heavenly Stem) and a lower character (an Earthly Branch). Your Day Master is the upper character of the Day pillar — usually highlighted in gold because everything else is read in relation to it.

Below the pillars, the reading walks through nine numbered chapters. The first chapter shows you the chart itself; the second is a prose interpretation that pulls together the most important patterns; the third surfaces the rarest features in your chart and the historical figures with similar configurations. The fourth — and most actionable for beginners — is the “Practical Translation” chapter: career patterns, core traits, and watch-outs for your archetype.

Chapters 5–8 are the technical layer: strength analysis, element balance, ten-god relationships, structural patterns, interactions between pillars (clashes, harmonies), symbolic stars, and the ten-year luck cycles that describe how your chart tilts over time. Skim these on your first pass and come back when you have questions.

If you only read one chapter on your first chart, read chapter ④ (Practical Translation). It is the bridge between the abstract structure of the chart and the concrete decisions you might actually use it for.

Calculate yours

You have enough to read your first chart. The form on the calculator page asks for your birth date, time, gender, and city — the city is used to apply true solar time, which is the longitude correction that makes BaZi accurate. If you don’t know your exact birth time, the form has an “I don’t know” option that defaults to noon and explicitly notes which parts of the reading become approximate.

The chart generates in under a second once you submit. Read it twice — once to understand the language, once to test it against three real decisions you have made in the past year. Notice where the framing matches your actual experience and where it doesn’t. The places it doesn’t match are as informative as the places it does.

You can come back to this site whenever you want and the chart will be exactly the same — the inputs and outputs are deterministic, and the calculator runs locally in your browser for the form state. No signup, no account, no email required.
