Marriage and love compatibility in astrology involve comparing the birth charts of two individuals to determine their potential compatibility in a romantic relationship. Astrologers analyze various factors, including the positions of the planets, their aspects (angular relationships), the signs and houses they occupy, and the Moon's placement.

Key points of analysis often include:

Sun sign compatibility: Comparing the zodiac signs of both individuals to see if they share compatible elements (fire, earth, air, water). Moon sign compatibility: Assessing emotional compatibility by comparing the Moon signs. Venus and Mars placements: Analyzing the positions of Venus (love) and Mars (desire) in both charts to understand romantic and sexual dynamics.
