How to Use Exact Degrees in a Synastry Comparison Report

What does the report actually do with supplied degrees?

Enter each person’s known Moon, Venus, and Mars sign. If you know a placement’s exact position within its sign, add that degree as well; if you do not, leave it unknown. A within-sign degree is the placement’s position from 0° up to, but not including, 30° of its sign. For example, “18° Taurus” pairs the sign Taurus with a position 18 degrees into that sign. The Synastry Comparison Report’s product page describes these as supplied inputs. It does not derive natal placements from birth dates, so first get the placements from a chart source you trust.

When both people’s degrees are available for a selected pair, the report can compare their zodiac positions geometrically. It measures the shorter angle around the zodiac and checks whether that angle lies within six degrees of one of five major aspect angles: conjunction, sextile, square, trine, or opposition. This is the report’s stated Western major-aspect convention and fixed inclusion rule. Supplying a degree makes that check possible; it does not itself create an aspect or establish how close the two placements are. The relationship between the two positions must be measured.

The distinction matters when you read the result. A sign tells you the placement’s sign context; an exact degree adds the position needed for the report’s selected angle checks. If either value is missing, the report cannot run that degree comparison for the pair. The available sign information remains usable, but an untested degree contact is not a finding that the placements have no relationship. Treat the report’s degree layer as one defined geometric comparison using the values you supplied, rather than as a chart calculated from birth details or a complete account of either person’s chart. This makes exact degrees useful as comparison inputs while keeping their meaning tied to a specific pair of recorded placements.

How can I keep both people’s placements and each comparison pair straight?

Record a placement as one indivisible row before comparing anything: person, planet, sign, degree. Then make each candidate comparison by naming both rows in order. A compact worksheet can use columns like this: Person | Planet | Sign | Degree | Source checked. Keep the person label attached to the placement when you copy it into a pair; a bare note such as “Moon, Taurus, 18°” becomes ambiguous as soon as you are looking at two charts.

For each candidate, write “Person A’s [planet] ↔ Person B’s [planet]” and copy the sign and degree beside each side. For example, the following is an invented illustration for organizing notes only, not a real chart or evidence about a couple: Person A, Moon, Taurus, 18° ↔ Person B, Venus, Cancer, 20°. This record preserves who owns each placement and what values you intend to compare. It also leaves the later angle calculation auditable: another reader can return to the two source rows and check the inputs rather than infer them from a result label.

Direction in the record matters even when the geometric angle is the same. A’s Moon compared with B’s Venus asks for an interpretation of those planetary functions in that ownership arrangement; A’s Venus compared with B’s Moon switches which person contributes each function. The arithmetic may yield the same separation, but the pair is not the same interpretive statement. Keep both labels visible through your notes and any discussion so that a shared angle does not silently swap the people or planets.

The instructional paper “Introduction to Relationship Astrology 2: Synastry” recommends making chart ownership visible in a two-chart grid, recording sign and degree, then calculating the separation under an explicit orb method. That is a useful bookkeeping discipline, not a requirement to adopt that paper’s particular thresholds or interpretive judgments. Check each entry against the chart source that supplied it. If a degree is unavailable, mark it “unknown” or leave the cell blank; do not estimate it from the sign, fill it from the other person’s chart, or turn a missing value into zero. The grid can produce many candidate rows. It keeps them straight, but it does not tell you which comparison matters most to the question you came to explore.

What is the difference between a sign relationship and a degree aspect?

A sign relationship describes how two placements relate by their zodiac signs within a chosen interpretive tradition. A degree aspect tests a different, more specific feature: the angular distance between the two positions against a named aspect angle. In the transcript “TAP Ep. 323 Transcript: Aspects in Astrology: The Five Major Configurations,” astrologers Chris Brennan and Claire Moon discuss both sign-based and degree-based configurations. The distinction is useful because a sign comparison can remain part of a reading even when the measured positions are not close to an exact major angle. One layer describes a sign-based configuration; the other checks geometric proximity.

The practical sequence is to keep the sign reading you already have, then add the degree result as a narrower statement. First note the signs and the relationship your chosen tradition assigns to that pair. Then, if both degrees are known, identify whether their separation is near a major angle and how far from exact it falls. A sign relationship does not, by itself, tell you the size of that angular gap. Conversely, a degree result does not replace all the meanings a reader may draw from the signs. It answers a bounded question about the two positions’ geometry.

That distinction also prevents a common wording error: “no degree aspect within this rule” is not the same statement as “the signs have nothing to say.” The report’s geometric output should be read as an angle check, not treated as the entirety of an astrological interpretation. This preserves the difference between the information supplied by sign comparison and the additional information made available by measuring degrees. It also keeps a report result from silently overruling a sign-based reading that belongs to another stated interpretive approach. The two descriptions can therefore coexist without contradiction: the signs identify one interpretive context, while measured proximity identifies another feature of the same placements. State which layer a sentence refers to, especially when a degree contact crosses a sign boundary or the signs do not form the sign-based configuration under discussion.

Astrologers do not all organize these layers identically. Some modern approaches center measured degree contacts and may not use sign-based aspects in the same way; other accounts retain sign-based configurations as meaningful in their own right. The transcript records this range of discussion rather than establishing one universal hierarchy. So describe each result by its actual method: a sign-based configuration under the tradition being used, or a measured distance from a specified aspect angle. Neither label alone settles how the whole chart should be read, and the two should not be collapsed into one claim simply because they concern the same pair of placements.

How do you calculate the shortest angle and its orb?

Convert each placement to a position on the 360-degree zodiac circle. Each sign occupies 30 degrees, so its starting point is found by counting 30 degrees per preceding sign from Aries at 0°. Add the placement’s within-sign degree to that starting point. Then subtract the two zodiac positions and take the absolute difference. If the difference is greater than 180°, use 360° minus that difference; this selects the shorter of the two arcs between the placements. The result is their shortest angular separation. A useful scratch line preserves both intermediate positions as well as the final angle: “28° Aries = 28°; 2° Leo = 122°; difference = 94°.” That makes it possible to locate an error in sign numbering separately from an error in choosing the shorter arc. Use the zodiac order consistently, beginning with Aries, Taurus, Gemini, Cancer, Leo, and then the remaining signs.

Next compare that separation with the exact angles for the five major aspects: conjunction 0°, sextile 60°, square 90°, trine 120°, and opposition 180°. An orb is the distance between the measured separation and an exact aspect angle. Nicholas Campion’s “An Introduction to Aspects and Chart Shaping in Natal Astrology” defines orb as the allowed deviation from exactness and describes approaches that assign allowances by aspect or by the planets involved. Here, use that term for the arithmetic distance, and apply the report’s stated six-degree inclusion rule to decide whether a candidate angle qualifies. The calculation identifies the nearest aspect geometry; it does not require treating every other candidate as though it were equally close.

Consider an invented example for arithmetic only, not a real chart: one placement is at 28° Aries and the other at 2° Leo. Aries begins at 0°, so the first position is 28°. Leo begins after four signs, at 120°; adding 2° gives 122°. The absolute difference is 122° − 28° = 94°. Since 94° is less than 180°, it is already the shortest separation.

Now check all five exact angles instead of stopping after a visually plausible match. The distance from 94° to a sextile at 60° is 34°. Its distance to a square at 90° is 4°. To a conjunction at 0°, the distance is 94°. For the opposition at 180°, use the shorter distance, 180° − 94° = 86°. To a trine at 120°, the distance is 26°. The square is therefore the nearest candidate, four degrees from exact, and it qualifies within six degrees. The trine does not qualify: it is 26° away. Checking each angle catches the consequential error of naming a plausible candidate while overlooking a closer one. In this example the separation is below 180°, so opposition cannot be the nearest candidate; nevertheless, its distance is 86°, which is the correct comparison with the opposite angle. Likewise, conjunction is evaluated against 0°, not against a second, unexamined route around the circle. Writing each distance beside its aspect makes the decision reproducible and shows exactly why the square, rather than the trine, passes the cutoff.

The same steps handle wraparound at the zodiac boundary. For instance, positions at 350° and 10° differ by 340° when subtracted directly, but 360° − 340° gives a shortest separation of 20°. This is a separate circle step, performed before comparing against aspect angles. Keep the operations in order: map each sign and degree, find the shorter arc, calculate its distance from each exact angle, then apply the stated orb rule. If displayed degrees have been rounded, this arithmetic describes the displayed inputs; it does not supply hidden precision or an extra rounding allowance.

How should I read the five qualifying aspect types?

The aspect name describes the measured geometry; it does not grade a relationship. The transcript “TAP Ep. 323 Transcript: Aspects in Astrology: The Five Major Configurations” identifies conjunction at 0°, sextile at 60°, square at 90°, trine at 120°, and opposition at 180°. These angles are the reference points. The report’s six-degree rule determines whether a measured separation qualifies near one of them; the label itself says what kind of angle is involved, not what two people will do with it.

A conjunction places two planetary positions at or near the same zodiac degree. Astrologers commonly read it as a joining or concentration of the functions involved: the planets operate in close proximity in the comparison. That can make their topics prominent together, but prominence alone does not tell you whether the experience feels supportive, demanding, or both. The planets and their owners still matter to the interpretive question.

A sextile is an angle of 60°. In conventional aspect language it can suggest an opening for cooperation or a resource that can be used. A trine is 120° and is often associated with ease or flow. Ease can be available without being noticed or deliberately developed; it is not a promise of agreement. A square, at 90°, is traditionally described as a tension or friction that calls for adjustment. That description can help frame what needs negotiation, but it does not establish that conflict exists or that a pair cannot work through a difference. The familiar contrast is therefore about the kind of question an aspect invites: what might be adjusted, or what ease is already available to draw on? It does not tell the reader how much effort either person will make, or whether the resource is shared in practice.

An opposition is 180°, with the two positions facing across the zodiac. Its conventional interpretive prompt is polarity: how might the two planetary functions be experienced as distinct, complementary, or in need of balance? This does not mean the people must oppose one another. A chart label is a symbolic question to explore against actual experience, not a report of behavior.

The contrast between a square’s adjustment and a trine’s available ease is useful only as a starting distinction, not a ranking. The transcript “TAP Ep. 323 Transcript: Aspects in Astrology: The Five Major Configurations” describes these as configurations within an interpretive tradition, while Nicholas Campion’s “An Introduction to Aspects and Chart Shaping in Natal Astrology” explains orb as distance allowed from exactness and discusses approaches that consider the planets involved. Together, these sources support naming the geometry and its reading convention; they do not make an aspect a relationship score. Ask what the two planets represent in this pair, whose placements they are, and what lived question the symbolism helps you consider. A close square may be more relevant than a close trine when the question concerns adjustment, while a trine may offer a useful resource to recognize. Neither geometry settles relationship quality by itself.

Which Moon, Venus, or Mars pair is relevant to my question?

Choose a pair by the concern you want to understand, then use its aspect and orb as geometric details. The Synastry Comparison Report accepts supplied Moon, Venus, and Mars placements with optional degrees, so a useful first step is to name the topic behind your question: emotional rhythms and comfort point toward the Moon; affection, preferences, and values toward Venus; initiative, pursuit, and desire toward Mars. These are interpretive prompts for selecting a comparison, not claims that one planet causes a particular response.

Make the prompt concrete before scanning the candidate contacts. If the question is about how each person seeks comfort or responds to daily emotional needs, begin with Moon-involving pairs. If it concerns how affection is expressed or what each person values in closeness, begin with Venus. If you are considering how initiative or desire is expressed, Mars may be the relevant starting point. A pair can involve the same planet on both sides or different planets; keep both labels visible, since Person A’s Moon to Person B’s Venus is a different interpretive arrangement from Person A’s Venus to Person B’s Moon, even when their angular separation matches.

Next, separate relevance from closeness. Among candidates that pass the report’s stated angle rule, a smaller orb indicates a closer geometric match to the exact angle. That helps order the geometry, but it cannot decide which contact speaks most directly to your question. A very close Venus contact may be less pertinent to a question about comfort than a wider qualifying Moon contact. Conversely, if your concern is affection and values, the Venus pair may deserve attention even when another candidate has a smaller orb. This is a relevance-first choice, not a universal ranking of planetary importance.

Keep a short selection note: “My question is ___; the pair I’m examining is A’s ___ with B’s ___; this is relevant because ___.” Then note the aspect name and orb separately, so geometric closeness does not replace the reason you chose the pair. For example, an illustrative conversation prompt based on an A-Moon/B-Venus comparison might be: “When I’m looking for comfort, what kinds of affection feel supportive to each of us?” The prompt does not predict either person’s answer; it gives the symbolism a question that can be checked in conversation.

If several contacts seem relevant, compare them in relation to separate concerns rather than collapsing them into one total impression. One pair may help you frame a question about comfort, another about affection, and another about initiative. The ordering can therefore change when the question changes, even though the placements and orbs remain the same. Record the person-planet direction for each candidate, state why it belongs to the topic, and use closeness only to describe its geometry. That leaves room for the actual interaction to confirm, complicate, or make the symbolic prompt irrelevant.

Why is six degrees a product rule rather than a universal boundary?

Six degrees is the Synastry Comparison Report’s consistent inclusion rule, not a boundary shared by every astrological method. That difference matters most for a pair close to the edge: under this report it either passes the stated filter or it does not, while another astrologer may be applying a different convention. Keep the convention attached to the result. A contact described under another method should not be silently substituted for the report’s output, and a report result should not be presented as though it settles every tradition’s judgment about orb.

The 2020 article “Estimation of aspect orbs by the computer” illustrates why one number cannot be treated as universal. In its discussion of synastry, the article reports an estimate of 9°–12° for conjunctions and trines from a cited prior comparison, and separately reproduces practitioner recommendations that vary by aspect and context, including recommendations wider than six degrees. These are different kinds of statements: the estimate is what the paper says a prior analysis yielded; the recommendations are practitioners’ proposed allowances. Neither is the same as a demonstrated threshold that every astrologer should use. The article describes selected datasets and computational approaches, and its synastry discussion does not directly test this report’s cutoff. Its figures therefore show variation in published estimates and advice, not a validated replacement for six degrees.

A different kind of variation appears in Deborah Houlding’s historical account, “The Classical Origin and Traditional Use of Aspects.” It describes a planetary-moiety method in which each planet has an associated orb and the two planets’ moieties are combined to set the reach of their aspect. Under that approach, the boundary depends on which planets form the pair rather than on one allowance applied identically to every candidate. Houlding gives Mercury–Moon as an example reaching a stated boundary at 9.5°, and Mercury–Venus at 7°. These figures illustrate that method as the article presents it; they are not the report’s thresholds and should not be read as modern consensus. The practical contrast is structural: one rule uses a uniform maximum, while this historical technique varies the permissible reach with the planets involved.

This variation changes how a borderline result should be compared, not just which number appears beside it. A fixed cutoff lets readers apply the same inclusion test across the report’s candidate pairs; a differentiated rule asks which aspect or planets are involved before deciding the permitted distance. The methods therefore answer related but not identical questions. When comparing notes with another reader, ask for the named aspect, the measured separation or orb, and the rule used to include it. That makes a disagreement inspectable: it may arise from different inputs, from a different boundary, or from a different interpretive method. Without those labels, two readers can appear to disagree about the placement when they are actually applying different filters.

For a near-boundary contact, record the method alongside the interpretation: “qualifies under the report’s six-degree rule,” or “considered under a named aspect-specific or planetary-moiety approach.” Then keep the readings distinct. If a contact falls outside the report’s filter, another convention may still invite a separate examination, but that does not change what the report calculated. If it falls inside, the consistent inclusion rule makes comparisons within this product easier to read, but consistency alone does not prove that all other boundaries are wrong or that six degrees is a universal natural limit. The useful conclusion is narrower: six degrees defines this report’s repeatable result, while the cited sources document other stated approaches and do not establish one correct boundary for every use.

What should I conclude when a degree is missing or a contact falls outside the cutoff?

There are three different outcomes to keep separate. When both degrees are available and the measured separation falls within six degrees of one of the report’s five aspect angles, that contact qualifies under this report’s filter. When both degrees are available but none of those five checks falls within six degrees, the tested pair is outside this report’s degree-aspect result. When either degree is unavailable, the report cannot test that pair’s angular distance at all. The last state is unknown, not a failed test.

The distinction affects what you can responsibly say. A qualifying contact is a result under the report’s stated convention; it does not determine how important the contact is to your question, a point addressed in the earlier selection section. A tested pair outside the cutoff means only that this report did not include it among its qualifying degree contacts. It does not erase the signs you supplied or establish that no sign-level interpretation is possible. A pair with missing degree data has no report-level degree verdict: do not call it absent, out of orb, or non-aspecting, because the geometric comparison was not available. Use the report’s unknown-input instruction from its scope section to keep that state visible rather than filling in a guessed value.

A simple note beside each pair can prevent these states from collapsing: “qualifies,” “tested, outside this cutoff,” or “not testable with supplied degrees.” The labels describe the status of the comparison, not its emotional tone or importance. In particular, outside-cutoff is a result of this report’s inclusion boundary; it should not be paraphrased as a weak aspect, because the report has no qualifying degree contact to interpret there. Not testable is different again: no statement about angular closeness follows until the missing input is supplied from a chart source the reader trusts.

For the previously calculated illustration, 28° Aries and 2° Leo produced a 94° separation, making the square at 90° the nearest angle with a four-degree orb. That example belongs to the qualifying state under the six-degree rule. If a different fully supplied pair were measured and every checked angle lay farther than six degrees, it would belong to the tested-but-excluded state; without one or both degrees, it would belong to the unresolved state instead. These labels preserve what is known without turning an unavailable measurement into a negative conclusion.

You can still discuss the signs when the degree layer is excluded or unresolved, provided you name the interpretive approach you are using. A sign-based configuration, where that tradition recognizes one, is a separate reading from a measured degree contact. Another astrologer might choose a different orb or examine sign-based configurations, but that is another stated method, not an aspect this report calculated. Keep the sign comparison available as its own layer, describe the degree result only when it was actually testable, and let the two statements remain distinct.

What is the next useful step with the clearest relevant contact?

Before using a contact as a prompt, verify that each placement belongs to the right person and that the signs and degrees match the charts you are consulting. Choose one qualifying pair that speaks to the concern you actually have. A close contact is not automatically the most relevant one; select the pairing that gives you a clear question about a real interaction.

If a Moon-to-Venus pairing brings comfort and affection into focus, you might ask, “When one of us needs reassurance, what kind of affection feels supportive?” Treat this as an invitation, not a prediction. Ask openly, then listen to the other person’s answer rather than fitting it to the symbolism. They may understand the interaction differently, or the prompt may not fit. That response can help you decide whether this is the concern you want to discuss or whether another question would be more useful.

The report can organize supplied comparisons and suggest a starting point for conversation. It cannot decide what the relationship means or should become. If you want to compare known placements, [Compare our placements](/compatibility-test). You can also use the question without the report: what happened, what did each of you need, and what would help next time? Let the conversation guide your next step.
