Next-Generation Engine For Canonical Astrologers
Canonical Rigor · Empirical Precision. Integrating NASA JPL DE440 celestial mechanics with orthodox traditional canons, making astrological calculation as verifiable as code.
Equipped with high-precision ephemeris models (2016–2050), pinpointing the exact solar term transition down to milliseconds. Resolves boundary disputes across 100,000+ global city coordinates with instantaneous true solar time adjustment.
ZhunPai is engineered for serious practitioners, eliminating empirical ambiguity and restoring metaphysical canons to absolute mathematical clarity.
For centuries, calendar shifts, coordinate inaccuracies, and the confusion between mean and true solar time generated persistent charting controversies. ZhunPai anchors its calculations directly to modern celestial mechanics, calibrating over 100,000 cities worldwide.
Engineering-Grade Architecture
From celestial physics kernels to AI semantic reasoning, every layer is academically validated.
Intelligent Natal Archive & Multi-Device Sync
A structured case management system built for astrologers. Organize charts by school (BaZi, Zi Wei, Liu Yao) with attached analysis notes. Client-side and cloud encryption keep records private and accessible across devices.
NASA JPL DE440 Celestial Engine
Leveraging the NASA JPL DE440 ephemeris model, ZhunPai computes Earth rotation variation (ΔT) and solar term transitions to the millisecond across 100,000+ global city coordinates.
One-Click Structured AI Prompt Export
Automatically converts multi-dimensional charts (BaZi, Zi Wei, Qi Men) into standardized, scholarly prompts copied straight to your clipboard. Paste seamlessly into DeepSeek, ChatGPT, Claude, or Kimi for deep AI pattern synthesis.
Empirical Case Verification Community
Share anonymized natal charts for consultation and follow-up outcome tracking. Organize review notes with flexible privacy levels (public, followers, private) in an empirical research ecosystem.
Six Canonical Metaphysical Disciplines
From natal blueprint analysis and spatiotemporal auspicating to dynamic divination, each discipline features a dedicated calculation engine.
Four Pillars (BaZi) · Ten Gods & Patterns
Precision early/late Rat hour division, day-level major cycle transitions, stem-branch strength, hidden stems, combinations, clashes, punishments, harms, and multi-decade time drills.
Purple Star (Zi Wei) · 12 Palaces
Tri-aspect palace aspect lines, quick switching between Zhongzhou, Sanhe, and Flying Stars schools. Accurate calculation of Si Hua transformations linked across decade, annual, and monthly charts.
Qi Men Dun Jia · Spatiotemporal Strategy
Full support for Chai Bu and Zhi Run rotating plates. Heaven/Earth plates, Nine Stars, Eight Doors, and Eight Spirits immediately reveal auspicious configurations, door clashes, and void palaces.
Liu Yao Divination · Lines & Hexagrams
Manual coin casting, time-based, and numeric input methods. Automated stem-branch assignment, Six Relatives, Host-Guest lines, Hidden Spirits, and Nuclear Hexagrams for logical divination.
Da Liu Ren · Heaven-Earth Plates
Rigorous monthly general placement, 9 Doors of initiation, Four Lessons, Three Transmissions, diurnal/nocturnal Noble Stars, and celestial spirit classifications.
Plum Blossom · Body-Use Dynamics
Time, object count, text character, and spatial casting methods. Automated calculation of Base, Mutual, Changing, and Interwoven Hexagrams with Five-Element interactions.
Empirically Verified Capabilities
From boundary cusp calibrations and cross-school confirmations to AI-assisted reviews, ZhunPai delivers verifiable mathematical foundations.
Births near solar term boundaries often suffer from misassigned month or year pillars due to equation of time errors (up to ±16 minutes). ZhunPai utilizes JPL DE440 ephemeris to pinpoint solar longitude down to seconds, eliminating disputes.
Single-system analysis has blind spots. BaZi reveals foundational strength; Zi Wei details palace interactions; Qi Men identifies spatiotemporal timing. ZhunPai binds them to a single temporal coordinate for instant comparative validation.
Inference depends on event timing. Legacy tools isolate decades, years, and months, making comprehensive clash/combination tracking difficult. ZhunPai's timeline slider enables real-time drill-down to pinpoint critical inflection nodes.
