What is BaZi?

BaZi (八字, “eight characters”) is an ancient Eastern art of reading character and timing, refined over roughly a thousand years since the Song dynasty.

Your birth year, month, day and hour are converted into the traditional solar calendar. Each becomes a pillar of two characters, a Heavenly Stem above an Earthly Branch, giving four pillars and eight characters in all.

Every character belongs to one of five elements: Wood, Fire, Earth, Metal and Water. How they feed, balance and challenge each other describes your natural tendencies. The stem of your day pillar, called the Day Master, represents you.

Each year, month and ten-year cycle carries its own elements too, which is why BaZi is especially good at questions of timing: when to push, when to consolidate, when to rest.

BaZi offers insight, not a verdict. Your choices stay yours.

Example conversation

I'm thinking about changing jobs this spring. What does my chart say about timing?

Spring brings Wood, which feeds your Fire Day Master, so it's a natural season for visibility and fresh starts. The tension point is early summer, when Fire runs high and you may overcommit. If you do move, try to decide by April and leave yourself room to settle before June.

From a reading

A Letter to You

When I look at your birth chart, I do not see a rigid blueprint of fixed fate, but rather a dynamic living landscape. In this landscape, your essence is Yin Metal — not raw, unyielding iron, but finely polished precious metal, a crystal, or a crafted gem.

Your healing lies in allowing yourself to be messy, spontaneous, and imperfect. Your voice does not need to deliver a finished masterpiece every time you speak; your raw truth is already luminous.

In readers' words

Unlike traditional astrology apps that hand down predictions of fortune and misfortune, or a fixed idea of fate, Yuna takes a gentler, more down-to-earth approach — breaking down your personality traits, life rhythms and growth trajectory. …It taught me that life is never an absolute dead end; every hard patch is just a phase. That gentle companionship, with no anxiety and no pressure, is this app's most precious quality.
小麻
I'm someone who's easily shaken and full of self-doubt. …What helps me most about Yuna is how it keeps growing with me — every answer makes me feel warm, comforted and hopeful, and helps me climb out of my own head and start again.
tao
What moves me most about Yuna is how closely it ties traditional astrology to what women actually face today. …It lets me use a traditional framework to explore my own potential, step by step, and write a sharper, stronger story about myself.
547***@qq.com
I'd been studying for exams for a long time, with no results to show for it, and I was anxious. …Talking with Yuna, it walks me through my strengths and weaknesses in detail and helps me set new goals. It doesn't just agree with everything I say — it's more like a friend who's always there.
Ann
Yuna named the energy in my chart gently but powerfully, and it left me firmly convinced that I can move and command wealth myself, instead of always relying on others — and it's made me more patient about building myself up.
安雅
It uses some technical terms really well. …I can genuinely see my own shortcomings and my strengths, and I feel steadier and more grounded inside. The wording especially strikes the right balance — gentle, but powerful.
wx_fF***
Yuna's writing is healing, the analysis is well organized, and the divination readings are detailed too.

FAQ

Good questions

How accurate is BaZi?

BaZi is a traditional framework, not a science, and no reading can tell you what will happen. What it does well is give you a consistent language for your tendencies and for the timing of your year. Most people find it useful as a prompt for reflection. Take what resonates and leave the rest.

What if I don't know my birth time?

You can still get a chart from your birth date; the hour pillar will simply be left open, and readings will say where that limits them. If you'd like to narrow it down, Birth Time Rectification works back from key events in your life.

What happens to my birth data?

Your birth details are used to calculate your chart and write your readings. They're stored securely, never sold, and you can delete your charts or your whole account at any time. See our Privacy Policy for the details.

Can I get a refund?

Yes, in several cases. A reading you haven't generated yet can be refunded within 14 days. If a reading fails or comes out broken, we'll regenerate it or refund you. Subscriptions can be cancelled anytime. The Refund Policy has the full terms.

Is Yuna a person?

No. Yuna is an AI guide. Your chart is calculated with established BaZi rules, and readings and answers are written by AI models working from that chart. They can make mistakes, so treat them as perspectives rather than facts.

What do I get for free?
