Synastry

Before You Start

Synastry compares saved charts.

• You need at least two saved charts. Save them in Astro Clock with Save chart.
• Chart A and Chart B must be different charts.
• The saved charts are used as they were saved. Changing the house system in Astro Clock does not recast a saved pair.

Open Synastry from the People group of the Astro Clock Tools bar. It opens in its own window; close it with the close button or press Escape.

Choosing The Charts

• Choose the first chart under Chart A.
• Choose the second chart under Chart B.
• Each chart's name, date, time, place and time zone appear under its list.

The report refreshes as soon as both charts are chosen.

Engine Tabs

• Memo: the narrative report
• Life Themes: a full-house engine organised as self-to-theme comparisons
• Union Dynamics: partnership and domestic compatibility, organised around bond and home
• Work Alliance: collaboration, built from the business houses (1st, 2nd, 6th, 7th and 10th)

Every tab recomputes from the same two saved charts and the same scope settings.

Scoring Scope

Below the tabs, Synastry shows the scope for the pair:

• Include: Modern planets, Nodes and Chiron
• Orbs: Tight, Balanced or Wide

These change the scoring layers and orb tolerance only. They don't rebuild the saved charts with the current Astro Clock settings. The window can warn when a layer, such as Chiron, isn't available.

Union Dynamics also shows Profile A and Profile B (Blended, Feminine or Masculine). Profiles don't change any score: every couple is scored on the same role-neutral pairings, and Feminine and Masculine only mark which Sun-Moon exchange Ptolemy singles out.

Reading The Memo

Overall Compatibility

The Verdict opens with the overall compatibility score out of 100 and whether it reads positive or negative.

Relationship Signature

The Relationship signature gives the pair a short verbal identity, such as "Mixed, but meaningful", and then breaks it into three axes:

• Ease
• Bond
• Growth

What Holds It Together And What Creates Strain

Two columns list the strongest supportive and straining contacts, each with its score and the factor behind it.

Deeper Sections

Further down, the Memo adds:

• Dimension scores: emotional resonance, communication, attraction and chemistry, compatibility and ease, attachment and longevity, growth and purpose, friction and conflict, and burden
• Evidence: the supporting and straining contacts in full
• House overlays: where each chart's planets fall in the other chart's houses
• Model and pressure: the scope and model in force, and the pressure summary

Reading The Structured Engines

Life Themes, Union Dynamics and Work Alliance open with a Verdict showing the composite total and the engine's own totals, for example the theme total and aspect total. These totals summarise the returned lists; they are not hidden scores from the source.

Work Alliance adds a Durability check built from three parts:

• the business-house foundation (theme base)
• the shared contact layer
• the pressure load

It answers a practical question: does the pair look able to hold a collaboration over time, or productive but exposed to stress.

Below the verdict, Reading notes name the strongest and most difficult areas. The structured view opens on Areas, with the areas diagram, each chart's thematic elements, element compliance and house importance. The other pages open the row-level tables for themes and the shared contact grid.

Practical Workflow

1. Save the two charts in Astro Clock.
2. Open Synastry.
3. Choose Chart A and Chart B.
4. Adjust Include and Orbs only if you want a narrower or wider reading.
5. Start with the overall compatibility and the relationship signature.
6. On a structured engine, start with the verdict totals, then the areas and row tables.
7. On Memo, move down into dimension scores, evidence and house overlays.

Notes

• Synastry needs two saved charts; it has no free-entry chart form.
• Include options such as modern planets or Chiron can be limited by the data available.
• Work Alliance uses the business houses 1, 2, 6, 7 and 10 and includes the durability check in its verdict.
