What is a progressed chart in astrology?

A progressed chart is an astrological chart based on the movement of the planets after birth. It is also known as a secondary chart, progressed horoscope, or derived chart. Unlike the natal chart, which is calculated based on the planetary positions at the time of birth, a progressed chart is calculated based on the movements of the planets over time.

The progressed chart is used to analyze how a person's personality, life circumstances, and future events may evolve over time. It is believed that the progressed chart provides insights into a person's spiritual growth, psychological development, and the challenges and opportunities that may come their way.

There are different methods to calculate the progressed chart, such as the secondary progression method, solar arc progression method, and tertiary progression method. Each method has its own unique approach to calculating the progressed chart, but they all involve advancing the positions of the planets in the natal chart to a certain point in time.
