jyotisha and the sky
What is a Janma Kundali and what information does it contain?
What a Kundali records
Janma means birth. Kundali means chart or diagram. Together they name the map drawn for the moment a person is born. It records the lagna, which is the ascendant, the point on the eastern horizon rising at that exact moment. It also records the positions of nine grahas, the planets of Jyotisha, across twelve houses and twelve rashis, the zodiac signs. The grahas include the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn, plus two lunar nodes called Rahu and Ketu. Where each graha sits in the chart, and how they relate to each other, forms the core of what a Jyotishi, an astrologer, reads.
Where it comes from
Jyotisha is one of the oldest branches of Vedic learning. The tradition of casting birth charts is foundational to it, and the Brihat Parashara Hora Shastra is among the most widely cited classical texts in this field. The system has been passed down through generations of practitioners, and its methods have been refined over a very long time.
The two chart styles
A Kundali looks different depending on where in India it comes from. The North Indian style uses a diamond-shaped grid of squares, and the houses stay fixed in position while the signs move. The South Indian style uses a square grid where the signs are fixed and the houses shift. Both carry the same information. Which format a family or astrologer uses usually comes down to regional tradition, not a difference in meaning.
What it is used for
Families use the Kundali in several ways across a person's life. At birth it is often cast to understand the child's nature and likely path. Later it is consulted for timing, to find auspicious moments for important events. In marriage, two Kundalis are compared in a process called compatibility matching, to see how well the charts align. Astrologers also read it to understand periods of difficulty or opportunity, using systems of planetary cycles built into the tradition.
Today
Many Hindus around the world still have a Kundali made at birth, sometimes by a family astrologer and sometimes through online tools that generate the chart automatically. Some people follow it closely. Others keep it as a family record without consulting it often. How much weight a person gives it varies widely by family, region, and personal belief. There is no scientific evidence that planetary positions at birth predict life events, and the tradition itself is understood by followers as a system of meaning and guidance rather than a fixed fate.
