What this section covers
Sun-sign horoscopes are everywhere; the material here goes a level deeper, into the parts of a birth chart that people look up once they have seen their own: a planet in a particular house, a planet in a sign, and the aspects between two people's charts in synastry. Each entry describes what the placement traditionally signifies, how it tends to show up in relationships, work and the inner life, where its difficult side lies, and how different schools of astrology — traditional and modern — read it differently.
How to use the entries
You will need your birth chart with houses, which requires a birth time; free chart calculators from established astrology sites provide it. Find the placement you are curious about, read the entry for it, and then follow the links to related placements: a planet's meaning shifts with the sign it sits in and the aspects it makes, so no single entry is the whole story. Entries that discuss famous people use only publicly known birth data and say so.
A note on interpretation
Astrology here is treated as a symbolic language for reflection, not a prediction of events. Where an entry describes a "challenging" placement, it is describing a tendency practitioners talk about, not a verdict on anyone's life.
