How to interpret the result
Read Venus and Saturn contacts first, since tradition ties them to affection and lasting vows, then any aspect to the Ascendant. In a constructed example, Person A has progressed Venus trine natal Saturn at 0.90 degrees and Person B has progressed Sun opposite natal Ascendant at 3.20 degrees, which puts that progressed Sun near B's Descendant, the traditional partnership point. That describes an inner focus on partnership around the date, not a sign that a marriage will happen or should.
