Cusps and Sandhis

Vedic astrology has several different view points of houses.

  1. Simple Rasi view: houses are the same as signs (starting from the sign of Ascendant resp. Moon). This system is most frequently used in Vedic astrology.
  2. Cusp view: houses start from the cusps and end at the cusp of the next house (like in western astrology). This view is used by the K.P. system.
  3. Sandhi view: houses start from the Sandhis (middle of the house). So the cusp is in the middle of the corresponding house. The corresponding chart is also called Chalita Chakra.
The vedic calculation tab of the configuration dialog has the option to switch between sandhi view and cusp view (check box K.P. Style House System).

Configuration of Houses

House systems can be configured separately for Vedic and western astrology in the Configure Western Calculation resp. the Configure Vedic Calculation tab of the configuration dialog.
