The twelve divisions of a natal chart, representing different areas of life and personal experience.
Definition
In astrology, houses are the twelve divisions of the natal chart, each corresponding to a specific realm of life. These divisions are based on the Earth's rotation and are calculated from the Ascendant (the degree rising on the eastern horizon at the time of birth). Each house governs distinct themes, such as identity (1st house), possessions (2nd house), relationships (7th house), and career (10th house). The houses are further divided into angular, succedent, and cadent categories, reflecting their strength and influence in the chart. The sign on the cusp of each house and the planets within them provide insight into how an individual experiences and navigates that area of life. Different house systems (e.g., Placidus, Whole Sign, Equal) exist, each with its own method of division, which can slightly alter the placement of house cusps and planetary positions. Despite these variations, the underlying symbolism of the houses remains consistent across systems.
In a chart
In a natal chart, houses are defined by the Ascendant and the chosen house system. Look for the signs on the house cusps and note any planets within each house. Pay attention to angular houses (1st, 4th, 7th, 10th) as they hold significant influence. Avoid reading empty houses as irrelevant; their ruling planets and cusp signs still provide information.
