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.
