Natal astrology and horary astrology differ primarily in their focus and the specific moment they analyze.

Natal astrology (or genethlialogy) is centered on the individual. It uses a horoscope plotted for the exact date, time, and location of a person's birth. Astrologers use this "map of the universe" to analyze an individual's character, personal growth, and life path, operating on the belief that celestial bodies exert an influence on the newborn.1

Horary astrology, by contrast, is a form of divination that does not necessarily require birth data. Instead, it involves casting a chart for the specific moment a question is asked. While natal astrology focuses on the "native" (the person born), horary astrology uses the dodecatropos (the 12 places or houses) to determine aspects of the "sublunar world" or the specific situation related to the inquirer's query.2

In both practices, astrologers examine the geometric relationships between planets, signs, and houses to derive their interpretations, though the intent behind the chart—understanding a life blueprint versus answering a specific, immediate question—remains the fundamental distinction.12
