Composite Relationship Chart

A chart for the bond you create together: its tone, support and tensions.

Your reading

How the reading works

Midpoints along the shorter arc between matching planets’ tropical longitudes. Opposite or ambiguous points are omitted. Birth dates are not averaged. Known times allow the midpoint of both ascendants and whole-sign houses; this is a composite convention, not a real horizon. Without a time, Moon, ascendant and houses are omitted, and other aspects have limited precision.

Symbolic meaning; the calculation does not establish personal traits or predict events.

What this tool helps you explore

The composite chart looks at a relationship as a whole. While synastry compares two people, this tool combines positions from both charts to explore the relationship's tone, support and tensions.

How to use it

Enter both people's birth details, select their cities and indicate whether times are known. Calculate the chart and explore the available planets, contacts and sections. You do not need to average dates or make calculations yourself.

Reading your result

Positions are symbolic midpoints, not the actual birth sky of a third person. Read contacts as relationship themes. Missing times mean less information; absent houses or Moon positions do not describe a quality of the relationship.
