Relationship Astrology

Davison relationship charts are part of a broader topic called in general “Relationship astrology”. This has to do with love, romance and finding a partner in life. Read more about relationship astrology topics.

Davison Relationship Charts

Ronald C. Davison

Ronald C. Davison (1914–1985) was a prominent astrologer in the mid-20th century, renowned for his innovative approach to relationship astrology. In the 1960s, he introduced a unique method of chart interpretation, offering a fresh perspective on understanding relationships through astrology. His approach builds on composite midpoint theory but adds a distinctive twist that has intrigued astrologers ever since.

Author of “Synastry”

Davison’s book, Synastry – Understanding Human Relations through Astrology. remains a classic resource. It explores the dynamics of interpersonal connections using astrological tools, cementing his legacy as a thought leader in synastry and relationship astrology.

The Davison Space-Time Relationship Chart

The hallmark of Davison’s contribution is the Davison Relationship Chart, which is calculated differently from a traditional composite chart:

Birthplace Midpoint

Unlike a composite chart that averages planetary positions, the Davison chart determines a physical midpoint between the two individuals’ birthplaces.

Time Midpoint

It also calculates a midpoint in time, based on the birth dates of the two individuals. This unique method creates a single chart representing the “relationship entity” as if it were an independent being.

Why the Davison Chart is Unique

The Davison chart offers insights that are more tangible and rooted in physical reality compared to composite charts. By integrating both time and space midpoints, it reflects the essence of a relationship as a distinct moment in the continuum of life, rather than just an abstract combination of energies.

Astrologers use this chart to:

• Analyze the purpose and destiny of the relationship.
• Uncover shared strengths and challenges.
• Understand how the relationship might evolve over time.

Davison’s innovative thinking continues to inspire astrologers, making his techniques an essential part of relationship astrology.

Davison Chart Example

Imagine one person is born in Europe and the other in South America.

The geographical midpoint between these two locations might fall somewhere in the middle of the Atlantic Ocean.

The Davison chart is then calculated as if this midpoint were a real location, anchoring the relationship in a specific space and time.

Theory of Davison Charts

A Davison chart is created by calculating the exact midpoint in time (mid-time and mid-date) and space (geographical location) between the birth times, dates, and places of two individuals. This midpoint generates a new chart representing the relationship as its own entity, with its own time, date, and location.

Key Features of Davison Charts

Mid-Time and Mid-Date

The chart reflects the exact moment halfway between the two birth times and dates.

Mid-Point in Space

The geographical location is determined as the physical midpoint between the two birthplaces. This unique approach anchors the relationship in both time and space, providing insights into its purpose, dynamics, and potential growth.

Davison vs. Composite Charts

Applications of Davison Charts

While Davison charts are most commonly used for romantic relationships (e.g., male/female dynamics), they are also valuable for interpreting other types of relationships, such as:

• Parent/Child relationships.
• Boss/Worker dynamics.
• Friendships or partnerships with significant interpersonal bonds.

The Davison method provides a grounded, tangible perspective on relationships, offering astrologers a deeper understanding of the connections between two people.

Davison Time Theory

To determine the Davison relationship time, the exact midpoint between the two individuals’ birth times is calculated.

Mid Time Example

If one person is born at 12:00 noon and the other at 6:05 PM on the same day, the Davison relationship time will be 3:02:30 PM. While it’s possible to calculate this manually, the process is complex and requires precision. Fortunately, astrology software like Astro Gold and Solar Fire can easily compute Davison charts, saving significant time and effort.

Davison Date Theory

The Davison chart is also based on the midpoint between the two birth dates, creating a “relationship birth date.”

Mid-Date Example

If one person is born on January 1st and the other on December 31st, the Davison date will fall around July 2nd or 3rd. For individuals born on January 1st, 1960, and January 1st, 1970, the Davison chart’s birth date will be January 1st, 1965—exactly halfway between the two dates.

Davison Key Takeaways

Specifics

Specifics of Davison charts.

• The midpoint in time and date anchors the Davison chart, reflecting the unique moment that symbolizes the relationship.
• This chart provides a practical and insightful tool for analyzing relationship dynamics.
• Modern astrology software make these calculations straightforward, allowing astrologers to focus on interpretation rather than math.

The combination of Davison time and date theories creates a powerful lens for understanding the deeper essence of a relationship.

Example Charts

Angelina Jolie

Birth data: 9:09am, June 4th, 1975, Los Angeles, CA USA.

Brad Pitt

Birth data: 6:31am, December 18, 1963, Shawnee, OK, USA.

Davison Jolie and Pitt

Midpoint Date

Find the midpoint date between Angelina Jolie’s birth date of June 4, 1975, and Brad Pitt’s birthdate December 18, 1963. The result is approximately September 10th, 1969.

Midpoint Place

Next you have to find the approximate place between the two places of birth Shawnee, Oklahoma and Los Angeles, California. I chose the city of Albuquerque, New Mexico. This is what I call the eyeball method.

Guess Davison Place

Midpoint City

It is interesting to guess the place closest to the two birth place’s midpoint and then to cast a chart for that place. This will certainly stretch you as an astrologer as you grapple with the time, date and place concepts for Davison Relationship charts.

Astrological Research

Innovation in a Timeless Practice

One of the most exciting aspects of Davison Relationship Charts is that this technique is relatively new in the world of astrology. This is in contrast to a field where many principles have remained largely unchanged for over two thousand years. While traditional techniques continue to provide profound insights, Davison’s work reminds us that astrology is a living, evolving practice.

Modern Invention

The fact that Ronald C. Davison devised this method in the 20th century is a powerful inspiration for modern astrologers. It highlights the potential to innovate, rethink existing paradigms and develop fresh approaches to interpreting charts. It’s a testament to the idea that astrology, like any discipline, thrives when its practitioners stay curious and open to exploration.

Dynamic

Astrology isn’t static, but rather it grows as we apply it to new questions, integrate modern tools and explore creative ways to interpret charts. Davison’s pioneering work serves as a call to action for all astrologers, just like you, to engage in research, experiment with new techniques, and contribute to the ever-expanding understanding of the cosmos. Even if you’re a longtime professional or you’re just beginning your astrology journey, remember that your insights and discoveries have the potential to shape the future of astrology.

What Will You Do?
