A Kundli, also known as a birth chart in Indian astrology, is a graphical representation of the positions of celestial bodies at the time of one's birth. It contains crucial information about a person's life, including their personality, career, and relationships. To create an online Kundli one can use various astrology websites and software. These tools require inputting the birth date, time, and place to generate an accurate chart. Kundli's analysis is used to gain insights into one's destiny and make informed decisions about life events, such as marriage and career choices, based on the positions of planets and their influence on an individual's life.
