What is Sect (Day vs Night Chart)?
Sect is one of the oldest and most important concepts in Hellenistic astrology. A day chart has the Sun above the horizon at birth; a night chart has it below. In day charts, the Sun, Jupiter, and Saturn are the sect benefics and malefics, functioning more positively. In night charts, the Moon, Venus, and Mars take these roles. Sect determines triplicity rulers and modifies how benefics and malefics express themselves.
