Progressed Chart Overview
Progressed Chart Overview
Progressed charts follow symbolic movements of planets after birth to show personal evolution. They reveal internal shifts that unfold over time and complement outer-world events seen in transits. Progressions highlight how a person grows beyond their natal blueprint and when significant life changes are likely to surface.
Primary Uses
- Trace maturation of the Sun, Moon, and personal planets
- Time periods of heightened development or crisis
- Correlate inner growth with external circumstances
- Forecast upcoming focus by watching sign and house shifts
Focus on progressed angles, lunation phases, and aspects to natal planets for clues about current life direction.
🧠Construction & Method
Secondary progressions use the symbolic key one day after birth = one year of life (day-for-a-year). For age n years, compute the chart for JD_birth + n × (1 day) (more precisely n × 365.2422 / 365.2422 days → 1 ephemeris day per tropical year). Typical rates: progressed Sun ≈ 0°59′/yr; progressed Moon ≈ 11°–15°/yr (≈ 1° per month), completing a full circuit in ≈ 27.3 years and a full progressed lunation cycle in ≈ 29.5 years. Solar-arc directions add the progressed Sun’s arc to every natal point; Naibod arcs use the mean rate 0°59′08″ per year.
