Your own chart is calculated from your birth details, and this definition is written out again there with your numbers in it rather than in the abstract. The chart, the glossary and thirty days of dated timeline are free, and nothing here is charged per question.
About a minute. Birth time optional, and no account until after you have seen it.
The points
The four angles and the nodes: places in the sky rather than bodies in it.
