Derived Houses
Derived Houses explains transparent house counting from a named person or topic. Inclusive counting 7 → 8 → 9 assigns the topic to the radical 9th house.
Overview
Derived or turned houses rotate house counting from a clearly named reference person or topic, so the reference point and counting direction must remain explicit. The page separates calculation from interpretation and keeps this worked result conditional: inclusive counting 7 → 8 → 9 assigns the topic to the radical 9th house. Verification follows this declared method: For a partner’s finances, start from the seventh house and count its second as the radical eighth, showing every step rather than relabeling the chart silently.

Definition and exact scope
derived or turned houses rotate house counting from a clearly named reference person or topic, so the reference point and counting direction must remain explicit
Calculation or decision rule
for a partner’s finances, start from the seventh house and count its second as the radical eighth, showing every step rather than relabeling the chart silently
Worked case and illustrative near miss
question concerns a spouse’s sibling; spouse starts at the 7th house; sibling is the 3rd from that house. inclusive counting 7 → 8 → 9 assigns the topic to the radical 9th house.
Illustrative near miss: Adding 7 + 3 and choosing the 10th house skips inclusive derived-house counting.
School and variant boundary
Tables and procedures differ by author, era, translation, and sect; the selected authority must remain visible.
Product, safety, and verification boundary
OpenFate presents Derived Houses as a sourced knowledge method and does not claim a dedicated calculator or generated reading for it. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Derived Houses cannot diagnose a person, remove consent, or guarantee an event.
