Davison Chart
A real astrological chart created from the midpoint in time and space between two birth dates.
About This Tool
- What it shows
- Draws a real chart for the moment exactly halfway between the two births, at the place halfway between the two birthplaces.
- What it’s for
- To read the relationship as a moment that really happened in the sky. Transits apply to the composite too, but only the Davison, being a real moment, can be progressed like a birth chart.
- What you need
- Both people’s birth date, time and place

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 average of the two birthplaces’ latitudes and longitudes. A standard chart is then cast for that moment and location.
