A Davison chart is cast for the exact midpoint in time and space between two births. That's what separates it from a composite: the Davison corresponds to a moment that genuinely existed in the sky.
What is a Davison chart?
Take the temporal midpoint of two birth dates and the geographic midpoint of two birthplaces, then cast an ordinary natal chart for that moment and location. The result describes the relationship as an independent 'third person'.
Because it is a real chart, every timing technique works on it — transits, solar returns, progressions — which is not possible with a composite.
How to read it
The Davison Sun shows the relationship's life purpose, the Moon its emotional rhythm, the Ascendant its outward face. House placements show which area of life the bond actually materialises in.
To look ahead, apply transits to the Davison chart: Saturn entering the Davison 7th house, for example, points to a period of commitment or restructuring.
Who is it for?
Couples who want to study the timing of a long-term bond, and astrology students who want to test a composite reading against real sky data.
Frequently asked questions
How is a Davison different from a composite?
A composite is symbolic, built from midpoints. A Davison is a real chart cast for a genuine moment and place.
Can you apply transits to a Davison chart?
Yes. Because it's a real chart, transits, progressions and solar returns all work on it.
Does it still work if the two people were born in distant countries?
Yes. Even if the midpoint lands in an ocean, the calculation is valid and symbolically represents the shared ground of the relationship.
