The Davison chart is a real sky chart cast for the exact midpoint in time between two births and the geographic midpoint between the two birthplaces. Unlike the composite, it corresponds to a moment that truly exists in the ephemeris — so transits and progressions apply.

Frequently Asked Questions
What is a Davison chart? ›
A relationship chart drawn for the moment exactly halfway between two birth times, at the point halfway between the birthplaces. It is based on a real moment of sky.
Should I use Davison or composite? ›
They are complementary: the composite shows the relationship’s archetypal identity, while the Davison works as a real chart that evolves in time. Serious work reads both.
Can transits be applied to a Davison chart? ›
Yes — that is its biggest advantage. Because it belongs to a real moment, current transits and progressions can be tracked meaningfully against it.
How is the midpoint computed? ›
Time uses the exact middle between the two birth moments; place uses the great-circle midpoint between the two birthplaces. A standard chart is then cast for that moment and location.
