A birth chart, also known as a natal chart, is a map of the sky at the exact moment and location of a person's birth. It shows the positions of the planets, the Sun, and the Moon in relation to the twelve zodiac signs and the twelve houses. Each element in the chart is believed to influence various aspects of an individual's personality and life experiences. Astrologers use birth charts to interpret traits and tendencies, providing insights into a person's strengths, challenges, and potential life path. Key components of a birth chart include the Sun sign, Moon sign, and rising sign, which together create a unique astrological profile for each individual.
