What the symbols mean ▾ the six questions
Every month, year and decade in your reading is one card — and every card answers the same few questions. Learn them once and you can read your whole report at a glance.
Is this period with me or against me?
FavorableMixedCaution
The overall climate. Favorable: a good time to act and push forward. Caution: go slower, be careful, protect what you have. Mixed: some of both.
What exactly is happening — and in which part of life?
/ detail lines · the life area
Specific events. The word says what kind of contact it is. The color says the direction: green helps you, red needs your attention, grey is minor — worth a glance, nothing more, and purple is a forced change with no direction either way — circumstances move you, and the outcome depends on what you do with it. The life area says where it lands: social world · career & parents · yourself & marriage · children & investments.
How strong is it?
⚠ double✦ doubleSame Pillar
Strength of impact. A double badge = the ten-year cycle and the year touch the SAME part of life in the SAME direction — that part counts double. It comes in both directions: when both press on that area, when both support it — a doubled support is one of the strongest windows a chart can show. A Same Pillar = the year’s stem AND branch are BOTH identical to the stem and branch of the ten-year cycle you are in — the same two characters ruling both layers at once (the classical 歲運並臨). The classics judge it by WHAT those two characters carry in YOUR chart: for some charts it is genuinely favorable, for a few it is heavy, and otherwise it simply concentrates the year — everything on the card counts more. Your report states which case yours is.
Is it about me personally?
⚭ bond⚭ bond · transforms
Who it lands on. A bond = the ONE sign in the whole cycle that pairs with your Day Master (the sign that represents you) arrives. Depending on your chart, its theme is either money and results, or position and recognition — and in a bond period that theme tends to arrive by itself: offers and openings come to you, instead of you chasing them. Usually the bond stays an engagement: the theme occupies you without changing you. Rarely it TRANSFORMS — the two energies fuse into a new element and the whole period takes on that new character; your report tells you which case yours is. At most one decade in a lifetime carries the bond, and the occasional year — which is exactly why it is worth noticing when it appears.
Which of my stars are active?
NobleAcademicSolitude
Your symbolic stars appear on the cards as small name-chips. A solid chip = a star you own — it sits in your birth chart, and this period makes it stronger. A dashed chip = a visiting star — a temporary influence you can use only during that period. The color follows the star: green = supportive, red = one that asks a little preparation — always shown together with its preparation, never as a bad omen. A marks a star’s single strongest window: its year and month arriving together.
Any special conditions?
Money vaultMoney vault↻ all-chart shift○ void☀ / ☔ climate$ build$ care
Extra notes. A vault chip marks a period touching one of your chart’s vaults — solid = a born-open store you own, stirred and amplified then; dashed = a closed store that period opens; green = the stored theme supports you, red = handle it with care (shown only if your chart carries a vault). A shift = a period whose nature is that several parts of life tend to change together — not something to prevent, simply its character. The advice is about the changes YOU control: spread your own big decisions out, one after another, so you are never carrying every change at once. A void = a less settled, searching stretch — it never changes a verdict, just a quality to know about. Your birth chart itself can also carry a void position (Death & Emptiness); Section 3 says so if yours does — and classically a combination or noble star in your own chart can neutralize it entirely, which is the most common case. A ☀ warming / ☔ cooling chip marks a favorable period that also carries the element a winter- or summer-born chart welcomes most — those periods help you twice over (shown only for charts the classical climate rule covers; explained in Section 3). The $ tags mark your chart's money rule: build years and careful years.
Every indicator is computed deterministically from your birth data — and the written analysis is required to agree with the cards.

Monday. Mei opens her map with her morning coffee. Today’s card says Caution — the day will ask more of her than it gives. But the month above it shows Favorable. Strange? Not really: the month is the season, the day is the weather. A rainy day happens inside a good summer. She plans a lighter Monday and moves one meeting.

Tuesday. A surprise: today shows a Clash — but it is printed in green. She taps the card. “Clears an element that works against you,” it says. So a clash is not automatically bad news. When the thing being pushed is a burden, pushing it away is a relief. Her map does not just name events — it tells her which direction they point for her.

Wednesday. She turns on the money lens. A few days this month glow $ build — days that favor her money life — and two show $ care: protect, don’t expand. She moves a big purchase off a care day. Ten seconds, one better decision.

Thursday. The real question: she must sign a lease soon. She opens the Finder, chooses “start · sign · open,” and asks for the next three weeks. The map checks two things for every day — an old rule, done properly: what the day is good for (the classical day types every almanac carries — an Open day welcomes signings; a Breaking day is kept for tearing down, not starting) — and how the day treats her, from her own birth chart. Only days that pass both doors appear. Most days fail. That is the point.

Friday. The finder’s answer surprises her: Tuesday next week, 9–11am. Not just the day — the hour. Each day carries its own good and poor hours, and the map crosses them with her chart. She notices something else: her best hours often repeat. That is not a broken clock — it is her chart’s fingerprint. Some people have one golden hour that repeats; hers is mid-morning. She starts booking important things there on purpose. And once in a while the map is honest enough to say the day’s finest hour runs from 1am to 3am — the middle of the night. She does not set an alarm — daytime choices are always listed beside it — but she likes that it never pretends: an hour can be perfect and still not be practical, and the map tells the truth and lets her choose.

Saturday. Her friend tries it and gets more careful days than green ones. Is his chart worse? No — his weather is simply more demanding, which makes his good days more valuable, not less. His map’s job is to find them for him. Hers teaches selection; his teaches timing. Same map, different rhythm — because it is computed from the birth chart, not from the calendar alone.

Sunday. She understands the map now, without reading a single rule: the calendar tells everyone what kind of day it is; your chart tells you whether it is your kind of day. The map holds both — and when you must choose a moment, it only shows days that pass both doors.

Months later. The Finder has one more door, and it is the tenderest. Mei and her husband are expecting, and the delivery will be scheduled — the doctor has offered three safe dates. The finder reads each one as the chart a child born that day would carry, alongside both parents’ charts — hers is already on the map; she adds his — and says which of the three it favors. Medicine decides what is safe; the map only helps choose among the dates the doctor already approved.

Every almanac tells you what the day is good for. Every BaZi app tells you what your chart says. Your Energy Map answers the question you actually have: is this my moment — and if not, when?

About Cosmic Guide

Why I Created Cosmic Guide

A long time ago, when I was still in high school, I had a wish: wouldn’t life be easier if each of us had a personal guide to help us choose our path?

Which school should I attend? What should I study? Which university should I choose? After graduation, which job should I pursue? Which company should I apply to? Which city — or even which country — should I build my life in?

As I grew older, the questions changed. Which home should I buy? What should I invest in? When should I act, and when should I wait?

Life is full of choices, and full of pitfalls. Some mistakes are the kind you can’t undo — one wrong step and you can spend years paying for it. I kept wishing for something that could help me understand the road ahead before I took the next step.

That search led me through many practices. Over the years, I explored the I Ching, Tarot, Reiki, yoga, pranic healing, different forms of meditation, face reading, BaZi, Feng Shui, Qi Men and Human Design. Looking back, I think I was always searching for the same thing: guidance.

I attended the courses, learned the methods and read stacks of books — and yet so much of it stayed just out of reach. The principles were difficult to bring together into one coherent reading. Even when working from the same information, coaches could interpret a chart differently, and it was never quite clear how all the rules should be reconciled in practice.

The arrival of AI opened a possibility that didn’t exist before. It gave me a way to examine the classical texts more closely, organise their rules, compare interpretations, and translate that knowledge into consistent calculations — ones that could be tested across many different charts, instead of being read a different way each time.

That became the beginning of Cosmic Guide.

I won’t pretend that BaZi — or any system — can tell you exactly which path to take. It can’t choose your school, your career, your home or your investments, and it can’t promise a fixed future. Nothing can.

But it can offer clues. It can help you recognise the themes, opportunities and pressures around you, understand why a certain season feels the way it does, and see where a little more care — or a little more courage — might be needed.

That’s what I built Cosmic Guide to do: not to decide for you, but to help you understand who you are, sense what may be coming, and take your next step with a little more clarity — the map I always wished I’d had.

The tradition

A thousand years of reading the pillars

BaZi — literally “eight characters” — has no single inventor. It was assembled over centuries into one of the most enduring systems of Chinese metaphysics.

The raw materials are ancient. The cycle of ten Heavenly Stems and twelve Earthly Branches was used to count days on Shang dynasty oracle bones over 3,000 years ago, and the yin-yang and Five-Element framework it rests on was systematised in the Han dynasty.

The first person credited with reading fate from birth data was Li Xuzhong of the Tang dynasty, who worked from three pillars — year, month and day. Two centuries later, in the Song dynasty, Xu Ziping gave the method its modern shape: he added the fourth pillar, the hour, completing the “eight characters,” and centered the reading on the Day Master — the self that everything else is measured against. To this day the method carries his name, Ziping.

What followed was refinement, not reinvention — through classical texts like Yuanhai Ziping, San Ming Tong Hui, and Zi Ping Zhen Quan, the last of which shapes the structure-based reading your report is built on.

FAQ

Questions, answered

How the reading works, what the terms mean, and the practical details.

About the reading
What is BaZi — and is it religious?

BaZi ("eight characters") is the classical Chinese method of reading character and timing from the exact moment of birth — four pairs of characters for your birth year, month, day and hour. It took its modern form in the Song dynasty and has been refined in written texts for about a thousand years. It is a framework for self-understanding and timing, not a religion — no belief or practice is required to use the reading.

Is this fortune-telling? Will it predict bad events?

No. BaZi describes patterns and tendencies — which periods support you, which ask more care, where your strengths naturally sit. Nothing in the report is a verdict or a prediction of a specific event, and every challenging pattern is presented with its practical preparation. We deliberately never write omens.

Does my chart decide my fate?

Your chart is a snapshot of your destiny taken at the moment you were born. But Chinese metaphysics has never treated that snapshot as the whole story. The classics read a life through three layers, the Three Powers (三才): Heaven, Earth and Man. Heaven is what you are given — your birth chart and its luck cycles, the timing sequence fixed by your birth data; neither is chosen by you, and this is the layer your report maps with precision. Earth is where you are — your environment and the people around you. Man is what you do — your conduct, choices, effort and learning: the steering. A well-known traditional saying, first recorded in the Qing dynasty, ranks the influences on a life — 一命二運三風水,四積陰德五讀書: "first destiny, second luck, third feng shui, fourth accumulating quiet good deeds, fifth study." In BaZi terms the first two are the Heaven layer — destiny is embodied in your natal chart, and luck means the cycles it moves through — while feng shui, good deeds and study are the layers you steer. Notice the saying deliberately ends on the parts fully within your control. The tradition never assigns percentages to these layers, and neither do we. Knowing the snapshot is what makes the steering deliberate — which is why every caution in this reading comes paired with its preparation.

How is this different from a horoscope app?

Two ways. First, precision of input: your reading is computed from your full birth data — year, month, day and hour — not just a sun sign shared with one-twelfth of humanity. Second, method: every pillar, star, date and label in your report is computed deterministically from the classical texts — the same rules a traditional master applies by hand, executed exactly, with nothing hand-waved. The written interpretation then explains what those computed facts mean for you.

Who writes the interpretation?

Two things are fixed: your chart and the rules. Every pillar, star, timing window and label is computed by our engine from the classical texts — identical no matter how many times you run it — and the written interpretation only explains what the engine computed, following an approved set of interpretation rules. Before any report goes out, a separate automated check verifies the finished text against those computed facts.

How do you know the rarity numbers are right?

They are not estimates. There are exactly 518,400 possible BaZi chart configurations, and every rarity the report prints — “carried by about 1 chart in 71” — is re-derived by enumerating all of them through the same engine that reads your chart, before every release. It is arithmetic, not opinion: anyone who knows BaZi can check the count themselves. The same discipline runs the other way — if your chart carries no rare feature, the report says nothing rather than inventing one.

Understanding your report
What are symbolic stars?

Classical patterns (神煞) that add color to a reading — some mark support, like the Nobleman (helpful people who smooth your path) or the Heavenly Doctor (recovery and care); some mark areas worth preparing for. Each star is anchored to a specific part of your chart, shown on its card. If a star's sign is in your birth chart, it's yours for life — and when the calendar brings its sign around, it's amplified. Stars you don't carry can still visit you in their years and months, active only for that period. Your report shows exactly which stars you carry, when each is amplified, and when others visit.

What does "favorable element" mean?

Every chart has a Day Master — the element that represents you. Depending on how well-supported it is, some of the five elements strengthen your chart and some drain it. The favorable ones are the wind at your back: periods, activities and directions carrying them run smoother for you. This is personal — the same element can be favorable for one person and demanding for another, which is why generic advice fails and a computed chart doesn't.

What do "strong" and "weak" Day Master mean? How is it decided?

Not a judgment — a configuration. The engine checks three classical factors: whether your birth season backs your element, whether your element has roots in your chart's four signs, and whether supporting elements hold the majority — with one strict classical rule on top: an element with no root anywhere is never counted strong, however good the season. The overall verdict decides which elements help you: with a well-supported ("strong") chart you thrive by spending your energy — expression, results, responsibility; with a lightly-supported ("weak") chart you thrive by drawing on learning, allies and support. Two winning strategies, neither better.

How is the wealth timing derived?

Three classical checks, applied to every coming year — each a pure table lookup, no scoring, no opinion. First, your money season: the years carrying your personal wealth element (the element your Day Master governs). If wealth is a friendly element for your chart, those are your build years; if you are still building the strength to carry wealth, those same years press on money instead — and your build years become the ones that strengthen you, because classically capacity comes first and money follows. Second, disturbance: any year whose sign strikes the place where your wealth element sits in your birth chart joins the careful list, however pleasant the year otherwise looks — the texts read it as a year money slips away more easily. Third, rivals: for a strong chart, years that bring back your own element in force can mean competitors reaching for the same money — unless the chart carries one of the classical safeguards: an outlet that turns rivals into contributors, or an authority star that guards the wealth. The build and careful lists never overlap; a year that triggers none of the checks simply carries no money tag. The written analysis is required to match the grid exactly.

How are the monthly and yearly tones (Favorable / Mixed / Caution) computed?

Each month, year and decade carries its own pair of elements. The tone is simply those elements checked against your personal favorable set — supportive elements only reads Favorable, draining ones only reads Caution; when the pair disagrees it usually reads Mixed — though when the upper element has no footing in the sign beneath it, the sign beneath decides (classically, a stem without a root carries little weight). Separately, the period's sign is checked against the four positions of your birth chart, and any classical interaction found — harmony, clash, harm, punishment, destruction — is listed with the life area it touches. The same two checks run at every timescale, which is why your months, years and decades can never contradict each other.

Practical
How accurate does my birth time need to be? What if I don't know it?

The hour sets one of your four pillars, so the closer the better — within the same two-hour window is fully accurate, since classical hours span two clock hours. If you truly don't know it, the other three pillars (year, month, day) still carry most of the reading; treat hour-specific details with lighter weight. If you later find your exact time, a fresh report will sharpen those sections.

What exactly do I receive, and how fast?

Your reading is prepared automatically after payment — usually ready within the hour, often within minutes, and always within 48 hours. The finished report is emailed to you as your permanent copy, and your personal link shows it online for 90 days. Your reading covers who you are, your life areas, your next 12 months, your next 12 years mapped year by year, the ten-year luck cycles — and closes on a short, personal reflection.

I paid, but my browser closed before the report finished. Is my payment lost?

No — your payment and your report are both safe. Your order does not depend on your browser at all: the moment you pay, it is queued on our servers, a confirmation email arrives with your personal link, and the finished report is emailed to you whether or not the page stays open. If anything ever looks stuck, just contact us — every payment is tied to your report, so nothing can be lost.

How does the Energy Map’s Birth window finder choose a delivery date?

It only ever ranks dates inside the window your medical team has already approved — medicine decides what is safe, the finder chooses among the safe. Every possible birth hour in that window becomes a full BaZi chart — the chart that child would carry — and each is scored on the classical checks: whether its core pattern comes together, how its decades run, whether it can hold wealth, whether anything presses on its health, and how it sits with both parents' charts. You receive the best three dates, ranked, with the full reasoning shown beneath each — and your doctor always has the final word.

I lost my Energy Map link — how do I get back in?

Your Energy Map link is private and works for your whole access period, on any device. First, check your delivery email (subject “Your Energy Map is ready”) — the Open my Energy Map button is your way in. If you can’t find it, go to your map page and use Lost your link? to have the link re-sent to the email you purchased with. Still stuck? Email hello@cosmicguide.app and we’ll help.

Is my birth data private?

Yes. Your birth details are used solely to compute your report and are never sold or shared. Payment is handled entirely by Stripe — we never see your card details. The full details are in our privacy policy.

Can I buy a reading for someone else — or for my child?

Yes — many readers order for partners, parents and children; you just need the accurate birth data. Children's reports are automatically written for a parent's eyes: growth-oriented, calm, with adult topics framed as patterns for later life.

Can you tell me the exact rules and tables behind my report?

The report itself shows you a great deal — every star's card names its anchor and its signs, every table names its interactions, and every timing label is explained where it appears. The complete rule set — the specific classical tables, their scoping and their reconciliations — is the result of our verification work against the source texts and stays proprietary, the same way a master's marginal notes do. What we promise instead is stronger: everything is deterministic, classical, and consistent — the same birth data always produces the same chart, labels and figures, every time.
