Kundli Milan vs synastry: how Vedic and Western astrology compare two charts

Both traditions compare two charts to see how a couple may get along. They go about it in different ways. Knowing the difference helps you read what each one is actually telling you.

Kundli Milan

Kundli Milan, or Guna Milan, is the Vedic system. It compares the Moon signs and birth nakshatras of two people and gives a score out of 36 across eight areas, called koots. It also checks the Manglik status of both charts and sometimes the 7th house and dasha periods.

• It gives one clear number and a list of cancellations.
• It leans on the Moon, so it speaks to mind, mood and family life.
• It is traditional in arranged marriages and widely used in India.

Synastry

Synastry is the Western system. It compares how the planets of one chart touch the planets of the other. It looks at aspects such as Sun to Moon, Venus to Mars and Moon to Moon, and at which houses of one person’s chart the other’s planets fall into.

• It gives a detailed picture of the dynamic between two people.
• It uses all the planets, not just the Moon.
• It does not give a single pass mark, so it takes more interpretation.

Using both

Many couples find it helpful to use both. A strong Guna Milan score with a few difficult synastry aspects suggests a good base that needs communication. A lower score with warm synastry suggests a connection that works if the practical sides are managed. Neither one decides whether a relationship will last.

Treat any score as a conversation starter. Talk about money, family, children and where you want to live. Those answers matter more than any chart.
