What is a Synastry Chart

A synastry chart in astrology compares the birth charts of two people to see how their astrological placements interact with each other. It helps in understanding the compatibility, dynamics, and connection between two people, often used in romantic relationships.

How to Create Your Free Synastry Chart

  1. Enter Names: Put the names of the two people.
  2. Enter Birth Places: Include the places of birth or the nearest city for both individuals.
  3. Enter Dates of Birth: Fill in the birth dates for both.
  4. Enter Birth Time (Optional): If you know the birth time, include it for a more precise chart. If not, we’ll use noon as the default time.

That’s it! Click “Create Chart,” and explore how the stars align in your relationship! Whether you’re curious about a romantic connection or want insights into any relationship, a synastry chart can offer unique perspectives.

My passion for astrology began in childhood with my grandpa showing me the stars and constellations. I grew up reading horoscopes and absorbing the knowledge from an astrology book, "The Sun Signs," that we had at home. Time has only deepened my love for astrology, leading me to create AstroMango. Here, I'm excited to share my lifelong passion with you!
