The first step in horoscope preparation is to calculate the Ascendant, or the sign rising on the eastern horizon at the time of the person's birth. This is an important factor in the chart, as it represents the person's outward appearance and general approach to life.

Next, the positions of the Sun, Moon, and other planets are calculated and plotted in the appropriate houses of the chart. Each planet is associated with different characteristics and influences, and their positions in the chart are believed to have a significant impact on the person's personality and life path.

Once the positions of the planets are determined, the horoscope chart is analyzed to gain insights into the person's life and future events. This analysis involves examining the relationships and aspects between the various planets, as well as the placement of the planets in different houses of the chart.

Horoscopes can be prepared for individuals, as well as for events and other points in time. For example, a horoscope can be prepared for the start of a new business venture, the signing of a contract, or the beginning of a new year.

Overall, horoscope preparation is a complex process that requires a deep understanding of astrology and the positions of celestial bodies. The resulting horoscope chart can provide valuable insights and guidance for individuals seeking to understand their personality, relationships, and future events.
