Free AI astrology: your birth chart, transits and Firdaria

Free Astrology Analysis separates astronomical calculation, traditional time lords, and modern predictive techniques. Begin with durable natal themes, then examine how weekly, monthly, and yearly cycles activate them.
What the platform can examine
- Natal motivations, emotional needs, relationship patterns, and life emphasis
- Stage changes shown by transits, progressions, solar returns, and solar arcs
- Exact Firdaria major- and subperiod boundaries with their natal basis
- Attraction, harmony, projection, and friction in relationship charts
- Historical-event backtesting against each period's internal baseline
How methods and evidence are organized
Readings follow the sequence natal promise, time lords, annual background, and current triggers. Calculated facts, astrological rules, and conditional inference are kept distinct. A single aspect is never treated as a guaranteed event.
The boundary between public content and personal data
This page contains only public methodology and product information. Birth data, personal charts, conversations, life events, and API keys remain within the user session and are excluded from public indexes, sitemaps, and AI-facing resources.
Limits of interpretation
Astrology is a symbolic interpretive tradition and has not been scientifically demonstrated to predict specific events reliably. Use it for reflection and planning; medical, legal, financial, and safety decisions require real-world evidence and qualified advice.
Frequently asked questions
Which predictive methods are supported?
Natal charts, transits, secondary progressions, solar returns, solar arcs, Firdaria, and annual profections are supported, with long-term background separated from short-term triggers.
Why is an accurate birth time important?
Birth time affects the Ascendant, Midheaven, houses, and several timing methods. Greater uncertainty requires greater caution with angle- and house-based interpretations.
Do scores represent event probability?
No. Scores compare relative activity within the same person and time-lord baseline. The reading remains grounded in chart structure and timing evidence.

Knowledge base
Guides to the core concepts behind AstroStarCheck: from Firdaria periods to aspects, synastry and report scores, grounded in the same calculations the tools run.
Sun signs in depth
Each of the twelve sun signs gets its own original article: personality, love, career and health, plus a note on how your rising sign refines it: a good first stop before you open a full chart.
Monthly horoscopes by sun sign
One page per sign, written against this month's actual transits: when to push, when to close things out, and what that means for work, money and relationships.
Relationship synastry and side-by-side charts
Enter two birth times and places. Each chart is calculated on its own first, then the two are laid over each other: where the pull comes from, and which part of daily life absorbs the friction.
Technical Foundation: Swiss Ephemeris WASM Precision and Browser-Side Security
Modern astrological computation demands exact celestial mechanics rather than approximations or mean orbital velocities. Our analytical engine integrates the Swiss Ephemeris compiled directly into WebAssembly (WASM), executing astronomical calculations locally within your web browser thread. By computing planetary longitudes, latitudes, speeds, and right ascensions using high-precision ephemeris files, the system accounts for planetary perturbations, lunar nutation, obliquity of the ecliptic, and light-time corrections. Coordinates achieve sub-arcsecond accuracy across historical and future spans spanning thousands of years.
Because calculations occur inside your client environment, your exact birth details, personal names, and life notes never transmit to external processing servers. This architecture unites astronomical rigor with total privacy, ensuring that charts, planetary house placements, and predictive timelines generate instantly without server latency.
The Natal Triad: Psychological Synthesis of Sun, Moon, and Ascendant
A birth chart represents a dynamic psychological architecture rather than a collection of isolated traits. The foundation of chart analysis rests upon the primary triad:
- The Sun (Conscious Will and Core Purpose): Represents the conscious ego, the central drive for individuation, vitality, and the deliberate direction of life goals. It indicates what an individual strives to become through focused effort.
- The Moon (Emotional Substrate and Instinctive Security): Reflects the instinctual nature, somatic responses, childhood conditioning, and subconscious emotional needs. It dictates how a person seeks safety, processes vulnerability, and responds under pressure.
- The Ascendant or Rising Sign (The Embodied Filter and Persona): Marks the exact eastern horizon at the moment of birth, serving as the physical vehicle, instinctual interface, and perceptual aperture through which the inner drives of the Sun and Moon engage with outer reality.
Synthesizing this triad clarifies why two individuals sharing the same Sun sign express their energy in fundamentally different manners. An Aries Sun with a Cancer Moon and Scorpio Ascendant navigates life with intense emotional sensitivity and strategic guardedness, whereas an Aries Sun with a Gemini Moon and Sagittarius Ascendant acts with rapid conceptual agility and outward exploration.
Predictive Hierarchy: Integrating Firdaria Chronology with Modern Transits
Accurate astrological forecasting avoids isolating single transits. Our platform organizes forecasting through a multi-tiered interpretive hierarchy:
- Natal Promise: The birth chart defines the constitutional capacity and structural boundaries of what can occur. An event or theme cannot materialize without a clear natal basis.
- Firdaria Time-Lords: Classical Persian-Arabic period systems assign specific multi-year life chapters to planetary rulers, establishing the prevailing life theme and psychological focus.
- Annual Context: Techniques such as Annual Profections and Solar Return charts define the immediate yearly emphasis and identify active house cusps.
- Dynamic Triggers: Real-time planetary transits and secondary progressions act as specific chronological triggers that activate the broader themes already prepared by the active time-lord.
House Systems: Whole Sign versus Placidus Comparative Analysis
House systems define how celestial coordinates map into earthly experience. The Whole Sign system assigns one entire thirty-degree zodiac sign to each house, anchoring the first house to the sign of the Ascendant. Originating in Hellenistic and early medieval traditions, Whole Sign houses bring exceptional clarity to planetary rulerships, sect dynamics, and time-lord techniques. In contrast, the Placidus system divides diurnal and nocturnal semi-arcs by time, creating house cusps of varying sizes that reflect geographic latitude. Comparing both frameworks allows readers to evaluate both thematic house rulerships and localized angular strength.
Frequently Asked Questions
How does WebAssembly enable high-precision astrological calculations?
By compiling the Swiss Ephemeris C libraries into WebAssembly, our platform executes sub-arcsecond astronomical calculations directly inside your browser thread, accounting for orbital perturbations and nutation without server processing.
Why is birth time precision essential for chart accuracy?
The Ascendant moves through the zodiac at approximately one degree every four minutes. An error of a few minutes shifts house cusps, planetary house placements, and can alter the diurnal or nocturnal sect determination in border cases.
How do Firdaria time-lords interact with planetary transits?
Firdaria establishes the multi-year macro chapter and primary planetary steward, while planetary transits provide day-to-day and month-to-month triggers that activate natal potentials governed by that steward.
What is the distinction between Whole Sign and Placidus houses?
Whole Sign houses align each thirty-degree sign with a single house starting from the rising sign, whereas Placidus houses divide celestial arcs by time, producing unequal house sizes based on geographic latitude.
How does the platform safeguard user birth data and chart privacy?
All chart generation and predictive algorithms run locally inside your browser via client-side WebAssembly, meaning personal birth details and notes are never stored or logged on public servers.
