Transit Chart Overview
Transit Chart Overview
A transit chart maps current planetary positions against a natal chart. It reveals how present cycles stimulate personal themes and when key events may unfold. Transit analysis helps anticipate opportunities, challenges, and shifts as planets activate natal and progressed positions.
Primary Uses
- Track timing of opportunities, challenges, and shifts
- Monitor long-term transits of outer planets for major life stages
- Prepare for short-term triggers from faster-moving bodies
- Integrate transits with progressions for a nuanced forecast
Focus on exact aspects to natal planets or angles, especially conjunctions and hard aspects, to gauge intensity and duration of effects.
🧭 Construction & Method
Transits compare the current sky (positions for the moment in question) with the natal chart. The arithmetic is the aspect test applied to transiting longitude vs. natal longitude. Key cycle lengths (sidereal periods): Jupiter 11.86 y, Saturn 29.46 y, Uranus 84.02 y, Neptune 164.8 y, Pluto 247.9 y; lunar nodes 18.6 y; Chiron ≈ 50.6 y. Typical life milestones follow from these: first Saturn return ≈ age 29–30, Uranus opposition ≈ 40–42, Chiron return ≈ 50, second Saturn return ≈ 58–59.
