MyArcana is several independent calculators plus two layers of reference material. The diagram shows the path of the data in each tool: what goes in, what is calculated, what comes out and where you can go next. A solid arrow is a link that exists inside the product; a dashed arrow is a step the reader takes by following a link or the navigation.

What is linked automatically

• Astrocartography lines and the wiki. The text that appears after you click a line on the map comes from the astrocartography wiki entries, the same ones that open in the wiki's Astrocartography section.
• Compatibility matrix and destiny matrix. Compatibility first calculates a personal matrix for each of the two people using the same algorithm as the destiny matrix page.
• Moon calendar and lunar horoscope. The pages link to each other, and the Moon's house in the horoscope is calculated with the Placidus system, as in the natal chart.
• Calculation history. Each calculator saves your results in the browser and lists them next to the form.
• Articles and calculators. Some articles link to calculators where you can test the topic on your own data, and the four latest articles are shown below the natal chart form.

What the reader does manually

• Natal chart → wiki. The result has no links to the wiki: the meanings of planets, signs and houses open separately, through Astro Wiki or the links in this guide.
• Matrix → arcana. Matrix positions do not link to arcana pages automatically: the result shows the arcana card, and the full meaning is found in the wiki's Arcana section.
• Tool → tool. Data is not passed between calculators: you enter the date and place of birth in each one separately.
• Wiki → wiki. Entries are self-contained reference pages that do not link to each other; the easiest way to move between them is the section index.

The calculator builds a map of the sky for the moment and place of birth and shows it as a wheel and a set of tables. The astronomical part is calculated by Swiss Ephemeris, the library behind a large share of professional astrology software.

What you need to enter

• A name, which is optional.
• The date of birth.
• The time of birth (hours and minutes) or the "I don't know my birth time" checkbox.
• The place of birth: city and country, with suggestions. The name is turned into coordinates, and the time zone is determined from them, taking historical changes such as daylight saving time into account.

What is calculated

• The positions of the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto in the signs, with degrees, minutes and a retrograde mark.
• Additional points: the true (north) lunar node, Lilith (the mean lunar apogee) and Chiron.
• The Ascendant and the Midheaven (MC).
• Twelve houses with cusp positions and the house of each planet; the default system is Placidus.
• Five major aspects (conjunction, sextile, square, trine, opposition) between planets, points, the Ascendant and the MC, with the exact orb.
• The Sun/Moon and Ascendant/MC midpoints, dominant planets and the distribution by element.

What you see in the result

A chart wheel with aspect lines: hovering over a planet or an aspect shows a tooltip, and the chart can be saved as an image. Below the wheel are tables: midpoints, planet positions, house cusps, dominant planets, dominant elements and a list of aspects. All of this is available without signing in.

Interpretation

The interpretation text is created by AI from the data that has already been calculated, when you press the button. Signing in with Google is required for this; the limit is 5 interpretations per day. It is informational and entertainment text, not a forecast and not professional advice.

Why the exact time and place matter

The signs of the Sun and the slow planets hardly depend on the birth time, but the Ascendant changes sign roughly every two hours (depending on latitude), and house cusps move even faster. Without an exact time, the Ascendant, MC and houses are therefore unreliable. If you tick "I don't know my birth time", the calculator uses a placeholder time (14:00): in that case rely only on the planets' signs, and check the Moon's sign separately, because it may be wrong if the Moon changes sign that day.

What is not available yet

The house system and the aspect orbs cannot be changed: they are the same for everyone. There are no general planetary transits, progressions or comparison of two natal charts; the only transit calculation is the Moon's house in the lunar horoscope.

The destiny matrix is a numerological system in which the numbers of the birth date are reduced to one of the 22 Major Arcana of the Tarot. Only the date is needed: the time and place of birth do not affect the result. The layout of positions follows the books on the Destiny Matrix method, and the formula is deterministic, so the same date always gives the same result.

What you need to enter

The date of birth (day, month, year), plus an optional name and gender, which the form asks for in some interpretations.

What is calculated

The base positions are the day, the month, the year (the sum of its digits), their sum and the center of the matrix (the comfort zone). From them come the ancestral square (the sky and earth lines, the mother's and father's lines), talents, the chakra map (physics, energy, emotions), the karmic tail, material and love karma, four purposes (up to 40 years, 40–60 years, general and planetary) and the energies by year of life over an 80-year cycle.

How to read the result

The result is an octagram that can be saved as an image, plus 16 thematic blocks. Each has the values of its positions in circles, the card of the matching arcanum, a mini-diagram with the highlighted points and an interpretation text; the last one is the "Action Map". The blocks are: birth energy, inner self, personality, the chakra health map, karmic tail, spiritual-creative, parent-child, material, love and money karma, soul mission, life script, talents, ancestry, current energy and year code. The health map is symbolic, not medical.

Texts and signing in

The first three blocks (birth energy, inner self and personality) are open without signing in; the remaining texts appear after signing in with Google. The texts are written by AI from prompts based on books: some are already stored in the database, and when a new combination of positions has no text yet, the AI creates it while you view the page and saves it. Every stored text is then reread by a person, and inaccuracies are corrected.

Where to find the meanings of the arcana

Separate pages for the Destiny Matrix arcana are collected in the wiki's Arcana section. The section is filled in gradually: 9 of the 22 Major Arcana are published so far.

• 1 The "Magician" Arcana in the Destiny Matrix
• 2 Arcanum "The High Priestess" in the Matrix of Destiny
• 3 Arcana "The Empress" in the Destiny Matrix
• 4th Arcanum "The Emperor" in the Matrix of Destiny
• 5 Arcanum "The Hierophant" (The High Priest) in the Matrix of Destiny
• 6th Arcanum "The Lovers" in the Matrix of Destiny
• 7th Arcanum "The Chariot" in the Destiny Matrix
• 8th Arcana "Justice" in the Matrix of Destiny
• 9th Arcanum "The Hermit" in the Matrix of Destiny

Wiki reference:Arcana

The compatibility matrix analyzes a couple from two dates of birth. It rests on the same system as the destiny matrix but looks at the relationship rather than at one person: the energies of two partners combine into a joint octagram of the couple.

What you need to enter

The name, gender and date of birth of each of the two people. The time and place of birth are not needed.

How it is calculated

First the calculator computes a personal matrix for each person, using the same algorithm as the destiny matrix page. Then the base positions of the two matrices are added pairwise, and the method's rules derive the couple's secondary points from them: the entry into the relationship, the financial channel, karmic points and so on.

What the result contains

Three metrics, "Relationship", "Union" and "Harmony" (the last sums the first two); a joint octagram of the couple; a comparison table of both partners' personal matrices; and 16 thematic blocks: the couple's atmosphere, first meeting, intimacy, what gets in the way, how to preserve love, the intimate sphere, karmic lessons, the couple's personal, social and spiritual purpose, a forecast for the couple, the couple as parents, tasks within the couple, material karma, the money channel and the couple's action map.

What is open without signing in

The calculation and the octagram are free and need no sign-in. The texts of the first three blocks (the couple's atmosphere, first meeting and intimacy) are open too; the remaining texts appear after signing in with Google.

How it differs from the destiny matrix

The destiny matrix describes one person: their talents, karma and purpose. The compatibility matrix shows how two people interact, and it suits any pair: romantic, friendly, business or family. Difficult arcana here are areas to work on as a couple, not a verdict on the relationship.

Wiki reference:Destiny MatrixArcana

Astrocartography shows where on Earth, at the moment of your birth, each planet stood on one of the angles of the sky: rising, setting, or at its highest or lowest point. These places are drawn on a world map as lines.

A name (optional), the date, time and place of birth: the same form as in the natal chart.

What is calculated

For twelve bodies (the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, Chiron and the true node) four lines are drawn: AC (rising), DC (setting), MC (upper culmination) and IC (lower culmination, the nadir). For the MC and IC lines, zenith points are also marked. Planet positions are calculated by Swiss Ephemeris.

How to work with the map

The map is interactive and built on OpenStreetMap: you can zoom and pan it, switch planets on and off in the list, and hover over a line for a tooltip. The birthplace is marked with a pin. Clicking a line opens its description below the map.

Mathematics and interpretation are different things

The positions of the lines are geometry, and the calculation can be checked. Their meanings are astrological tradition: the descriptions for each "planet + line" pair come from the astrocartography wiki entries, while the AI interpretation of the whole map is created on request (sign-in required, up to 5 per day) and suggests where in the world, by astrological logic, certain themes are amplified. This is an interpretation, not a measured property of a place.

Accuracy

The birth time is critical here: an error of one hour shifts the MC and IC lines by roughly 15° of longitude. That is why the "I don't know my birth time" checkbox is of little use for astrocartography: a placeholder time produces placeholder lines.

Wiki reference:AstrocartographyPlanets

Two sections deal with the Moon: the general moon calendar and the personal lunar horoscope.

Moon Calendar and Moon Phases

The page needs no data and shows the Moon's state for today or for any date chosen in the calendar. It includes the current phase and illumination, the key phases (new moon, first quarter, full moon, last quarter) with the nearest one, the lunar day, the zodiac sign and degree of the Moon, its age, the distance to the Moon and the Sun, the angular diameter, moonrise and moonset, the Moon's aspects to the planets over the day, Void of Course periods, the nearest solar and lunar eclipses and a monthly calendar.

Moonrise and moonset are calculated for a typical city of your language version, not for where you are.

Lunar Horoscope

The daily horoscope is built from three factors: the lunar day, the Moon's sign and the phase. This part is the same for everyone. The personal part appears after you enter a date, time and place of birth: the calculator determines which of the 12 houses of your natal chart (Placidus) the Moon is in today and picks the text by house, sign and phase. You can view the horoscope for another date. Birth data can be remembered in the browser with the "save locally" checkbox.

What is calculated and what is interpreted

The positions of the Moon and the Sun, the sign, aspects, Void of Course and eclipses are calculated with Swiss Ephemeris; illumination, the Moon's age, moonrise and moonset come from the SunCalc library. The meanings of the lunar day, sign, phase and house are astrological interpretations: texts written by AI from prompts based on books. They are neither scientific fact nor a forecast of events.

Astro Wiki is a reference in which every concept has its own page: an image, a short description, a full article with navigation by headings and comments (you can leave them after signing in; they are published after moderation). There are five sections; you can switch between them with the navigation at the top of each section and with the cards on the wiki home page. Each entry page has breadcrumbs: Astro Wiki → section → entry.

In this language version, 55 entries are currently published.

Wiki entries do not link to each other, so the easiest way to move between them is the section index or the lists below.

The Articles section is a feed of publications from newest to oldest. Each article has an image, a teaser, a full text with navigation by headings and comments. Topics: astrological forecasts and transits, retrograde planets, eclipses and lunar events, natal chart elements explained (the Ascendant, aspects, planets in signs and houses), the destiny matrix and karmic tails, astrocartography, tarot and zodiac signs.

The section has no categories, search or filters: you navigate by headlines and teasers.

Articles cover individual topics in more depth than the short wiki entries, and some of them link to calculators where you can test the topic on your own data.

The astronomical part is deterministic and can be checked, while the interpretation is astrological tradition and text created with the help of AI. Below is what the calculations rest on and where their limits lie.

Astronomical data

The positions of the planets, the Moon, the Ascendant and the houses are calculated by Swiss Ephemeris, an astronomical library with ephemerides based on NASA JPL data. The birth time is converted to UTC using the time zone of the place, determined from coordinates with historical changes taken into account. The place is looked up by name: first in a built-in city database, then through the OpenStreetMap Nominatim and Google geocoding services; the first match found is used.

Houses and aspects

The house system is Placidus. If it cannot be calculated for very high latitudes, the calculator tries Koch, Regiomontanus, Campanus, the Equal House system and Whole Sign in turn. The aspects are the five major ones with fixed orbs: conjunction 8°, trine 8°, opposition 7°, square 6°, sextile 4°. The house system and orbs cannot be changed.

Dominant planets and elements

Dominants are calculated with a weighted scheme that takes into account dignities (rulership, exaltation, detriment, fall), the type of house, closeness to the chart angles, rulership of the Ascendant, Sun, Moon and MC, and the planet's aspects. It is MyArcana's own scheme, not a generally accepted astrological standard.

Destiny and compatibility matrices

The calculations are numerological: the numbers of the day, month and year are reduced to the range 1–22 (if a number is above 22, its digits are added), and the derived positions are sums of earlier ones, also reduced to 1–22. The result does not depend on the time or place of birth. There are different schools and variants of the matrix layout, so other calculators may give different positions.

Moon calculations

The Moon's sign and degree, aspects, Void of Course and eclipses are calculated with Swiss Ephemeris; illumination, the Moon's age, moonrise and moonset come from the SunCalc library. The data updates every time the page is opened or another date is chosen.

Limits of accuracy

• The result depends on the data entered: a mistake in the date, time or place produces a different chart.
• Without an exact time the Ascendant, MC and houses are unreliable, and in astrocartography so are the positions of the lines.
• For small places that share a name, include the country: the calculator takes the first match it finds.
• Astrology, the destiny matrix and tarot have no scientific confirmation: they are symbolic systems for reflection and self-discovery, not forecasts of events or the advice of a doctor, psychologist, lawyer or financial adviser.

The role of AI

The meanings of positions and arcana are collected from books and practice, and AI (language models from Anthropic and Google) turns them into readable text. The texts of the matrix, compatibility and moon page blocks and of the wiki are stored in the database: some are prepared in advance, some are created while a page is viewed, and a person rereads all of them and corrects mistakes. Natal chart and astrocartography interpretations are created on request for one specific result, so there is no manual check of each of them. Translations into other languages are also done by AI, so some phrases may sound less natural than the original. How we describe our own editorial practice is on the About page.

Is registration required

The calculators, moon pages, wiki and articles work without an account. Signing in is only through Google. It is needed for AI interpretations of the natal chart and astrocartography (up to 5 per day for each tool), for the full set of text blocks of the destiny and compatibility matrices (three blocks are open without signing in) and for comments.

Where results are stored

Finished calculations are stored in the browser of this device and are available in the calculation history on the tool's page. The limits are 20 natal charts, 20 matrices, 15 compatibility matrices and 10 astrocartography maps; older ones are replaced by newer ones. A link to a result works only in the same browser, and the history can be cleared. In the lunar horoscope, birth data is remembered in the browser with the "save locally" checkbox.

What is sent to the server

For a calculation, the data you enter is sent to the site's server, and the place name is sent to geocoding services to find coordinates. For AI interpretations, the calculation result is passed to the providers of the language models. The full rules, including cookies, analytics and advertising, are in the privacy policy.
