Why This Technique Matters
Prognostics & Event Timing · Astroprognostic
Inner readiness for life changes
While transits bring external events, progressions mirror internal emotional evolution and maturity to meet those events.
The Progressed Moon Cycle (~27.5 years)
Moving at ~1° per month, the progressed Moon completes the zodiac in ~28 years, breaking life into distinct 2.5-year developmental chapters.
Progressed luminary ingresses
When the progressed Sun or Moon ingresses into a new sign, it marks a foundational transformation in outlook, priorities, and identity.
✅ What the Engine Calculates
- Astronomical tropical constant: 1 day = 365.24219879 days of life
- Arcsecond precision calculation of the progressed Moon
- Major aspect matrix linking progressed bodies to natal cusps and planets
- Dual-wheel natal + progressed overlay with interactive navigation
✕ Can't do:
- Doesn't give dates as sharp as transits — this is inner, not outer, timing.
