These tools serve as mechanisms for determining an individual’s lunar nodes within an astrological chart. Inputting birth details like date, time, and location allows the algorithm to compute the precise positions of the north and south nodes. This calculation is based on the intersection points of the Moon’s orbit and the ecliptic, the apparent path of the Sun across the sky.
Understanding these nodal positions is considered significant in astrological interpretation. They are believed to reveal karmic patterns, past life influences (south node), and the direction of growth and fulfillment in the current lifetime (north node). Examining these points can provide insights into personal challenges, potential strengths, and the individual’s overall life purpose. The practice has historical roots in Vedic astrology and has been adapted into modern Western astrological traditions.
