Birth Chart Calculator – How Your Kundli Is Calculated
A birth chart is a detailed map of the sky at the exact time, date, and place of your birth. It shows the positions of the planets, Sun, and Moon, along with other important astrological elements at that moment.
In astrology, a birth chart helps you understand your personality, strengths, challenges, and life patterns. It also gives insights into key areas of life such as career, relationships, health, and decision-making.
To calculate a birth chart, three key details are required — your date of birth, exact time of birth, and place of birth. Even a small change in these details can affect planetary positions and change the overall chart.
A birth chart calculator uses accurate astronomical data along with Vedic astrology principles to calculate planetary positions and create your chart.
