How our divination is calculated

Many services just hand you an answer without saying how it was worked out. We believe you feel more at ease when a reading is computed and traceable. So we lay out the basis of every method openly — what is real astronomical calculation, what is traditional calendar charting, and what is symbolic inspiration.

Our principle: compute what can be computed with verifiable methods; chart traditions faithfully without dressing them up as science. Every reading is a reference to understand yourself better — not a verdict on your fate.

In short

At Qi Yi Crystal, Western astrology and Human Design compute planetary positions from real ephemeris (VSOP87 + NASA JPL data, verified against JPL Horizons, ~±1 arcminute); BaZi and ZiWei use the traditional solar-term calendar; numerology uses a reproducible number system; everything is done by AI computation with no human fortune-teller, and results are for reference and reflection, not guarantees.

Core engine: real astronomical ephemeris

Observationally verifiable

Applies to: natal chart / synastry, yearly forecast, 2026 transits, Solar Return, Saturn Return, Human Design, Astrocartography

◆

Planet positions: VSOP87 planetary-motion theory (a high-precision international standard)

◆

Pluto: TOP2013 model (for slow outer-planet orbits)

◆

Ephemeris constants: astronomical constants from NASA JPL's DE405 ephemeris

◆

Coordinate transforms: US Naval Observatory (USNO) NOVAS algorithms

◆

Verification: cross-checked against NASA JPL Horizons

◆

Overall precision: planetary longitude within about ±1 arcminute (1/60°)

◆

Coordinate system: tropical zodiac (of date), consistent with international astrology / Human Design

In plain terms: where Saturn sits on your chart, and whether it touches your Sun, is an astronomical fact — computed and consistent with authoritative NASA ephemeris, not something we made up. That's why we're confident doing time-critical readings like the 2026 transits and the Solar Return.

The basis of every other method

BaZi · ZiWei · Chinese Zodiac: traditional calendar charting

Classical system

Applies to: BaZi yearly, ZiWei Dou Shu, Chinese zodiac, Korean Saju, Chinese almanac

BaZi (Four Pillars) uses the solar-term calendar: the year begins at 'Li Chun' (Start of Spring) and months change on solar terms. From your birth data we derive the Heavenly Stem and Earthly Branch of the year, month, day and hour pillars, then tally the five elements. This step is pure, reproducible calendrical calculation.

ZiWei Dou Shu casts the twelve palaces, the brightness of the main stars and the four transformations from your birth date and time — the skeleton of the chart.

These are metaphysical traditions passed down for centuries. We chart them faithfully by the classical rules, but we do not dress them up as modern science.

Human Design: 13 bodies at two precise moments

Astronomical

Applies to: Human Design

Human Design needs two charts: the 'Personality' chart at birth, and the 'Design' chart about three months before. The Design moment is solved precisely as the instant the Sun was 88° of arc earlier — not a rough 88-day estimate.

We compute 13 celestial bodies at both moments from astronomical ephemeris, convert them into the activated gates of the 64-gate wheel, then derive your Type, inner Authority, Profile and channels from a deterministic table — the calculation layer involves no AI guesswork.

Chiron & North Node: sign-entry date tables (sign level)

Table lookup

Applies to: Chiron sign reading, North Node (soul-growth direction)

Chiron is a minor body that standard ephemeris engines don't include, so we use a table of the dates Chiron entered each sign (1926–2045, including every retrograde back-and-forth), based on Cafe Astrology's Chiron tables and cross-checked against Zane Stein and the Siddhantika ephemeris. It is accurate to the sign; if your birthday falls within a day of a sign change, we ask for your birth time rather than guess.

The North Node is also a table lookup, not an arc-minute calculation: we use the dates the mean node entered each new sign (roughly every 18.6 months, 1944–2029). It is accurate to the sign; if you were born within about two weeks of a sign change, your node may fall in the neighbouring sign.

Numerology & number readings: reproducible arithmetic

Computed

Applies to: Life Path number & personal year, angel numbers, phone / plate number readings

From your birth date or a number, we compute the result by the relevant number system (Life Path numerology, number 'energy', etc.). The process is fully reproducible. It's a Western and folk number tradition, offered for reflection and reference.

Tarot & symbolic readings: spreads and imagery

Reflective

Applies to: Tarot, one-question oracle, past life

The system draws a random tarot spread, then reads it through each card's meaning and symbolism to offer reflective, projective insight — useful for seeing things from a new angle and processing how you feel right now.

We frame them honestly as inspiration and entertainment. They do not claim to predict the future, and are never used to frighten or pressure you.

Palm & face reading: traditional physiognomy, read from your photo

Photo-based

Applies to: Palm reading, face reading

Palm reading follows traditional palmistry: first the hand type (metal, wood, water, fire or earth) from palm shape and finger length, then the life, head and heart lines and the minor lines. Face reading follows traditional Chinese face reading: face shape, the three facial zones (upper, middle, lower), the features and any visible moles.

Only features that are clearly visible in your photo are read — if the light is too dim, the angle is off or something can't be seen, we'll ask you to retake it rather than guess. It's a traditional way of observing, used to reflect on where you are and your habits right now; it is not a prediction, and it never labels your personality from your looks or your lines.

Dream reading: symbolic imagery

Symbolic

Applies to: Dream reading

Based on the dream you describe, we look at common symbols from folk dream lore and at psychological views (such as Jung's) on how dreams relate to your emotions and recent experiences, to suggest what the dream may be saying.

Dreams mean different things to different people, so we treat this as a prompt for self-reflection — never as an omen of good or bad luck, and never to frighten you.

What does the AI do?

The computation, charting or draw above produces a structured result (sign degrees, four pillars, a chart, gates, a number, a spread). Our AI assistant turns that into a plain-language reading close to your daily life.

The reading is based on those computed results, not invented; it is done entirely by AI computation with no human fortune-teller — which is exactly why we can serve you 24/7, instantly and consistently.

Glossary

Ephemeris
A table of where celestial bodies are at each moment — the basis of every astrological calculation.
VSOP87
A planetary-motion theory that yields high-precision planet positions; one of the international standards.
DE405 ephemeris
A high-precision planetary/lunar ephemeris published by NASA's Jet Propulsion Laboratory (JPL), widely used in space missions and astronomy.
JPL Horizons
NASA JPL's online ephemeris system, regarded as an authoritative reference; we cross-verify our results against it.
Arcminute
An angular unit; 1 arcminute = 1/60°. A ±1 arcminute error is far smaller than the apparent width of a full moon — more than enough to place a sign.
Tropical zodiac
A zodiac measured from the spring equinox; the standard for Western astrology and Human Design, which we use throughout.
Solar terms (Li Chun)
The mainstream basis of BaZi charting: the year starts at 'Li Chun' rather than on a lunar or calendar new year, and months change on solar terms.

☯ The Qi Yi Two-Layer Method: a base for life, an accent for the year

Qi Yi's own design method

Our custom bracelets follow a two-layer design we developed ourselves. Layer one is your base — your BaZi five elements, Chinese zodiac, life-path number or star sign. It never changes, and it decides the main stones and proportions of your bracelet. Layer two is this year's accent — each year we swap just 1–2 beads to echo the year's theme, leaving the base untouched.

Layer two has a distinct basis per line: BaZi bracelets read the Zi Wei annual palace (a traditional charting rule); zodiac bracelets read Tai Sui relations (clash, punishment, harm, break — from traditional almanac rules); life-path bracelets use the personal-year number (standard numerology); star-sign bracelets follow Jupiter's transit (Jupiter's position is astronomical fact; houses use the solar whole-sign method). Every calculation is deterministic and reproducible — the same birthday always yields the same result.

Honest disclosure: the calculations have traditional or astronomical grounding, but mapping a year's theme to a specific crystal is Qi Yi's own interpretation, not an industry standard. Accent stones are always chosen to harmonise with your main stone's element. Crystals are symbolic companions — never a guarantee. We designed it this way because we believe the honest approach is: your base never needs re-buying; only the year's accent changes.

FAQ

What is the Qi Yi Two-Layer Method?

Our own bracelet design method: layer one is your lifelong base (BaZi five elements, Chinese zodiac, life-path number or star sign), which decides the main stones; layer two is this year's accent — just 1–2 beads swapped annually based on the year (Zi Wei annual palace, Tai Sui relations, personal-year number or Jupiter's transit). All calculations are deterministic and reproducible; mapping a year's theme to a specific crystal is Qi Yi's own interpretation, not an industry standard.

Do I need to re-buy my crystal bracelet every year?

No. Under the Two-Layer Method your base design never changes — only the year's accent moves on. Swapping 1–2 beads each year is enough; for example, a dark guardian-stone accent in a Tai Sui year, adjusted again the following year.

Is divination scientific?

It depends. The 'planetary positions' used by Western astrology and Human Design are astronomical facts that can be observed and verified; but the interpretation of astrology and BaZi is a metaphysical and cultural tradition, not modern scientific proof. Our approach: compute what can be computed with verifiable methods, chart traditions faithfully without dressing them up as science, and offer the result for self-reflection.

Is AI astrology accurate? Is there a real fortune-teller?

Our divination is done entirely by AI computation, with no human fortune-teller. The system first computes or charts a structured result (sign degrees, four pillars, chart, etc.), then AI interprets it in plain language — the reading is based on those computed results, not made up. Content is for reference and reflection, not a guarantee.

How are planetary positions in Western astrology / Human Design calculated, and how accurate?

With a professional astronomical ephemeris engine built on the VSOP87 planetary theory and NASA JPL DE405 ephemeris constants, cross-verified against NASA JPL Horizons; planetary longitude stays within about ±1 arcminute (1/60°), using the tropical zodiac, consistent with international standards.

How is BaZi (Four Pillars) worked out?

BaZi uses the solar-term calendar: the year begins at Li Chun and months change on solar terms. We derive the Heavenly Stem and Earthly Branch of the year, month, day and hour pillars, then tally the five elements. The charting is pure, reproducible calendrical calculation.

How is ZiWei Dou Shu charted?

From your birth date and time we cast the twelve palaces, the brightness of the main stars and the four transformations, then AI interprets the chart in plain language. It is a traditional system and needs an accurate birth time.

How is Human Design calculated?

It requires two moments: the 'Personality' chart at birth and the 'Design' chart about three months earlier. We compute 13 celestial bodies at both moments from ephemeris, map them to the activated gates of the 64-gate wheel, then derive Type, inner Authority, Profile and channels from a deterministic table — no AI guesswork in the calculation.

What is Astrocartography?

Astrocartography projects the planets of your birth chart onto a world map, drawing the lines where a city or region amplifies your career, love, mentor or wealth energy. The same chart feels different by location, useful as a reference for travel, relocation or expanding a market.
