Natal chart · BaZi · Conversation

A companion who knows your sky.

Your natal chart and four pillars, calculated to the degree by our own engine. A conversation that remembers, a calendar that prepares your appointments — and every morning, the heart of your books in one line: productivity, health, direction.

Calculated to the degree Every term translated into plain English No prediction

The conversation space on a phone: the morning notification, an exchange that picks up a pattern already seen, and the day pillar 甲子.

The companion

Talk. Remember. Act.

The calculated sky is not the product: it is the ground. What you make of it is a conversation that remembers you — and helps you move.

Screenshot of the conversation space: morning notification, a pattern picked up again, the day pillar.

Talk

You write as you would in a notebook. The answer works from your chart and from what you have already shared — no predicting, no flattery. The tone adapts: holding on hard days, challenging on stuck ones.

Screenshot of the memory: patterns detected and fact journal.

Remember

People, events, places, challenges: every exchange is read back. Repetitions are linked and shown — “three times this month already” — never lectured, never blamed.

Screenshot of the calendar: a flagged appointment, a cue before, a debrief after.

Act

An appointment that weighs on you gets a cue the day before and a debrief after. Accepting a suggestion becomes an appointment, with no re-entry. One intention at a time — no coaching in bursts.

A day with Les Ciels

The morning sets the direction.
The day puts it to work.

7 am · the summary

The best of your books

The email picks what is most useful in your books for the day: productivity and health first, one direction, one question. Not a data stream — a sentence to lean on.

One gesture · the thread

You answer

The question opens in the conversation. You answer in one line; the companion picks up where you left off, memory included.

The day · the calendar

Appointments prepared

Calendar and conversation side by side. The day before a flagged appointment, a a cue; after it, a debrief question that joins your memory.

Evening · your books

The day's editions, ready

Your three day editions are dated, archived and downloadable from your day. What you read today no longer changes tomorrow.

The morning summary does not replace your books: it skims them for you. The full detail — calculations, decoders, chapters — stays in the day's PDFs.

Three books, one birth

Your books, in depth

The morning summary skims them; the books tell them in full. One birth moment, read by two traditions that never knew each other, then by what they say together. Every fact followed by its translation, every term defined.

The morning summary

Seven o'clock, one direction

Every morning the email does not unpack your books: it picks the best of them for the day — productivity and health first — and leaves the rest one click away.

Your best hours

The hours that carry your element: when to launch, decide, ask, or simply talk.

What pushes back

The tense transits of the day, named without drama, and what they ask you to let go of.

The body

What the five elements say about your energy today: where to spare yourself, where to hold.

One action only

Not a list of advice: one concrete thing to do today, and one to put off until tomorrow.

The morning summary: the best of the day's books, one direction, and the day's editions to download.

The method

Three steps, no approximation

1

Your birth

Date, time and place of birth. We recompute true solar time for your location: that is what gives the Ascendant, the houses and the Hour pillar.

2

The calculation

Positions come from the VSOP87 ephemerides and a high-precision lunar model. On the Chinese side, the 干支 cycle is computed from the solar terms.

3

The book

Your positions are laid out, then decoded or interpreted depending on the edition. You get a paginated A4 PDF, with the full calculation notes.

Let us be clear

It is not a belief. It is a method.

BaZi is not a fad. It is a Chinese calendrical system more than a thousand years old, still used today to make decisions, including in business. Here is why we take it seriously.

First of all, a calendar

BaZi rests on the 干支 cycle, used to count days since the oracle bones of the Shang dynasty. Three thousand years of continuous use. The twenty-four solar terms 节气 that pace it are astronomy: the Sun's real position on the ecliptic.

A business practice

In Hong Kong, Taipei and Singapore, companies regularly consult a practitioner before opening a store, choosing a brand name or signing a contract. It sits next to the numbers, not instead of them.

Not a science, and we will never say otherwise

BaZi cannot be proved in a laboratory, and we will not pretend otherwise. It is a symbolic system, like Western astrology: serious in method, but without scientific proof. It gives you a vocabulary for describing yourself and a calendar for choosing your moment. It is not a proof, it is a tool.

To help, not to predict

We will not tell you what is going to happen. We sell no luck, no protection, no shortcut. We light up what you are already living, and the decision stays yours. It is the only promise we can keep. It is enough for us.

The Chinese calendar does not predict the future: it gives the present moment a name. That is how we use it, and how we invite you to read it.

Sample pages

A few pages, just as they are

Every technical datum is followed by a golden line in italics: its translation into plain English. You can always skip the figure and read the translation.

Our position

What we will not do

Two languages, no hierarchy

We do not say the East is right and the West wrong. The two systems light up different things: character on one side, balance on the other. They correct each other.

Both sides, always

Every trait comes with its good side and its hard side. A reading that only flatters helps no one.

Genuinely calculated

Ephemerides, longitudes, angles. No approximate “sign of the day”, no position invented to round off a sentence.

Nothing opaque

Every word is explained, and you can redo the calculations yourself. Check every claim, reread your chart years later.

What it keeps — and your rights

A companion, not a black box

Nothing leaves without your consent

The conversation opens with an explicit consent screen that names the processing in plain words. Until you tick the box, nothing leaves this server.

Where your messages go

Depending on the model that answers, your messages may be processed in France (EU rules), the United States or China. Never for advertising, never to train a model.

Export and deletion

Everything is exportable as JSON from your account; deleting the account erases conversations, memory and calendar. Books you have already received remain yours.

Help, never predict

The companion predicts nothing and replaces neither a doctor nor a therapist. It helps you see clearly and take action — the rest is yours.

Questions

What we are asked most

Do I need to know my exact time of birth?

For the Ascendant, the twelve houses and the Hour pillar, yes — half an hour of difference can change the Ascendant. If you do not know it, say so: the chart is then drawn without the houses, and the book says so instead of filling the gap with a guess.

Why pay, when the free edition exists?

Because they do not do the same job. The free edition gives you the facts and the keys to read them: it is a learning companion, and it is yours forever. The subscription does the reading work for you — it weaves your portrait, connects the two traditions, and writes to you every morning. It is the difference between a score and someone who comes to play it for you.

Are your readings written by artificial intelligence?

In the free edition, no: the translations come from a knowledge base written and checked by hand, and nothing is generated at the moment of the run — hence an instant, perfectly reproducible result. In the subscription, yes: the daily reading and the conversation's answers are written by a language model, guided by the exact positions of your chart and by that same base. It draws nothing at random, and you can check every statement in the facts printed alongside. We would rather say it plainly than keep it vague.

Is the conversation a therapist?

No, and it will never claim to be one. It is a space for writing and stepping back, grounded in your chart. When it senses distress it slows down and suggests talking to someone rather than playing a role that is not its own. For anything medical, legal or financial, it points you to a professional.

Where do my messages go, and what happens to my memory?

The conversation opens after explicit consent. Depending on the model that answers, your messages may be processed in France (EU rules), the United States or China — never for advertising, never to train a model. Your memory (people, events, places, challenges) is exportable as JSON from your account and deleted with it.

Can I read without the conversation?

Yes. The three books and the day editions read on their own, and the free edition calls no language model at all. The conversation and the calendar are an extra layer, never an obligation.

Is it magic?

No. It is an exact astronomical calculation, read through a symbolic system — just as a score can be read as a story without the score ceasing to be music. What the reading is worth, only you can say.

What time does the daily email arrive?

At 7 am in your time zone, by default. You can choose another time, pause the sends while you are away, or switch to a weekly rhythm — without losing access to your books.

Can I cancel, and what happens then?

Yes, in one click, at any time. Sends stop at the end of the paid period, and the books you have already received remain yours: you can download and reprint them whenever you like.

Are the books included in the subscription?

Yes. The subscription gives access to all three books in full — Under the Sky of Birth, Under China's Stars and West & China — in their edition with interpretation, plus the daily email. You can regenerate your books at any time if your details change.

What happens to my time of birth?

It is used only to draw your chart and calculate your daily reading; it is kept for the life of the account, then twelve months (the life of your reading archive), then deleted. No birth data is used to train a model.

Can I print my book?

Yes: the books are A4, in deep black and white on a night background, with a layout designed to stay readable in print as well as on screen.

Over to you

Your sky is waiting.
This time, it answers.

Start for free: you will see exactly what we calculate before deciding anything. And if the morning summary speaks to you, the subscription brings it every day — with the conversation and the calendar.
