The Technology Behind The Fifth Pillar
Astronomical precision meets AI synthesis
Swiss Ephemeris
The foundation of all calculations. The Swiss Ephemeris is the same astronomical engine used by professional astrology software worldwide, computing planetary positions with sub-arcsecond accuracy. Every planetary placement in your reading is calculated from actual astronomical data — not approximated from tables or simplified algorithms.
Lahiri Ayanamsa
For Vedic calculations, The Fifth Pillar uses the Lahiri ayanamsa — the standard used by the Indian government's official astronomical almanac. This precisely converts tropical (Western) positions to the sidereal zodiac, ensuring accurate nakshatra and pada placement for every chart.
BaZi Pillar Engine
Chinese Four Pillars of Destiny calculations derive year, month, and day pillars from the traditional sexagenary cycle — 10 heavenly stems combined with 12 earthly branches. Five Element analysis identifies your elemental constitution, revealing which elements dominate, which support, and which create tension in your chart.
Pythagorean Calculation
Numerology numbers are derived through authentic Pythagorean reduction — preserving Master Numbers 11, 22, and 33 when they appear. Life Path from birth date, Expression from full birth name, Soul Urge from vowels. Each calculated through traditional methods, not simplified shortcuts.
AI Synthesis Engine
The proprietary synthesis layer processes all four system outputs simultaneously, identifying cross-system convergence patterns, resolving inter-system contradictions, and generating structured output with numbered insights and system citations. This is not a generic AI writing paragraphs — it's a specifically engineered synthesis methodology that understands the relationships between astrological traditions.
Privacy-First Architecture
The Fifth Pillar uses stateless architecture — your birth data is processed in real-time and your reading is delivered to your session. No birth data is stored in databases. No personal information is retained beyond your reading session. Your cosmic blueprint stays yours.
