Sect: Day and Night Charts
Day and night classification from the Sun and horizon. This guide gives a reproducible rule, worked example, illustrative near miss, and explicit limits.
Overview
Sect classifies a chart by whether the Sun is above or below the horizon and assigns traditional diurnal or nocturnal affiliations under specific authors. The page separates calculation from interpretation and keeps this worked result conditional: the chart is diurnal; day-specific triplicity or time-lord rules may now be selected explicitly. Verification follows this declared method: Calculate the Sun’s house-relative horizon position, label day or night, then state which sect table and treatment of twilight or horizon contact is used.

Definition and exact scope
sect classifies a chart by whether the Sun is above or below the horizon and assigns traditional diurnal or nocturnal affiliations under specific authors
Calculation or decision rule
calculate the Sun’s house-relative horizon position, label day or night, then state which sect table and treatment of twilight or horizon contact is used
Worked case and illustrative near miss
☉ at 18°♌ in the 10th whole-sign house, above the ASC–DSC horizon. the chart is diurnal; day-specific triplicity or time-lord rules may now be selected explicitly.
Illustrative near miss: Calling the chart nocturnal because the clock time says 23:00 even though the calculated Sun is above the local horizon.
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 can expose the chart inputs needed for Sect: Day and Night Charts, but it does not claim a dedicated automated interpretation for this technique. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Sect: Day and Night Charts cannot diagnose a person, remove consent, or guarantee an event.
