Core meaning
What the Square means
The square places two planetary functions in a relationship of friction and adjustment. The repository frames this as productive friction rather than as an inherently bad event. One function can complicate or press against the expression of the other, making the relationship harder to ignore. The interpretive value lies in identifying what needs a concrete response without forcing one side to defeat the other.
Squares tend to make competing demands visible. Their tension can support action, revision, or clearer differentiation, but no specific response or outcome follows automatically. The planets identify the functions under pressure; signs and houses add style and life-area context.
Angular geometry
From observed separation to orb difference
Exact square is 90°. An observed separation of 86.5° has an orb difference of 3.5°, calculated as the absolute distance from 90°. The aspect is accepted only if that difference falls within the square limit for the calculation context being used.
Exact angle
The canonical target for this aspect: 90°.
Separation
The smallest observed angular distance between the two calculated points.
Orb difference
The absolute difference between observed separation and 90°.
Repository orb policies
Maximum orb depends on context
These values are separate calculation policies, not competing universal claims. The exact 90° geometry remains the same in every context.
Current-sky and natal planet aspects
±6°
Used by the repository's default planet-to-planet major-aspect calculation, including the natal chart's planetary aspects.
Personal transit-to-natal aspects
±3°
Used when a current transiting planet is compared with a natal planet in the personal transit system.
Compatibility and Synastry aspects
±5°
Used when a supported point in Person A's chart is compared with a supported point in Person B's chart.
Opportunity
Constructive expression
use pressure to make a concrete adjustment or decision.
Challenge
What needs care
avoid forcing one function to defeat the other.
Practical reading guidance
Relate two planetary functions without overclaiming
Name the two functions separately and examine where their aims or timing are difficult to reconcile. Read the square as a request for adjustment, not proof of conflict, failure, trauma, or a negative personality trait. A tighter orb can indicate a closer geometric match, but it does not replace whole-chart interpretation.
- ✦Separate the planetary functions before describing their friction.
- ✦Do not convert tension into a deterministic negative prediction.
- ✦Use the applicable orb context when deciding whether the 90° relationship is present.
Birth Chart relevance
Natal Square
In a birth chart, a square can describe a recurring need to work consciously with two natal functions whose expressions do not always fit together easily. It does not predict a particular event or establish an individual's biography.
Compatibility relevance
Synastry Square
In Synastry, a square can describe cross-chart tension, competing expression, or adjustment between two supported points. It does not prove arguments, incompatibility, abuse, breakup, or actual behaviour.
