Synastry aspect library

Learn the aspect.
Keep the people in view.

Focused relationship guides for personal-planet and selected outer-planet contacts people actually search—each paired with a private check against two birth charts and a calculation receipt that shows orb and birth-time limits.

What synastry adds

Look at how two charts meet, not just two sign labels.

Synastry compares placements from two birth charts. An aspect can be a useful way to reflect on the meeting point between identity, emotional needs, communication, affection, motivation, or first impressions. It cannot determine the health or future of a relationship.

Use an aspect as a question: where do we feel easy, where do we need more language, and what does care look like when this difference is activated? That keeps the chart in a proportionate role and keeps the people in the relationship visible.

Velvet Zodiac also keeps calculation confidence visible. If a Moon has no recorded birth time, the calculator tests its daily longitude window instead of promoting a single noon Moon as exact. Exact angles and receiving-house overlays require a usable birth time; the site omits them when that precision is not supported.

For a fuller reading, add the House Overlay Library to see where each person’s planets land directionally, compare the cross-chart contacts with the Composite Chart, then use the Composite Aspect Library to read the midpoint geometry. The Relationship Report keeps those lenses separate first, tests declared approximate-time ranges minute by minute, then classifies repeated themes as Reinforced, Counterbalanced, or Tension between lenses without turning them into a compatibility score.

Common questions

How should I read a synastry aspect?

Is one “bad” aspect enough to rule out a relationship?

No. No single aspect predicts a relationship outcome. Consider the broader chart, the relationship context, boundaries, values, and how the people involved actually communicate.

Do I need both birth times for synastry?

No. Many planetary contacts can still be compared without both times. When a Moon is untimed, Velvet Zodiac tests a daily Moon window and labels supported contacts Stable or Conditional instead of printing a noon Moon as exact. Rising, MC, and exact receiving-house overlays still require a usable birth time.
