Do aspects change between tropical and sidereal charts?
A purely angular aspect computed from the same pair of physical longitudes can remain unchanged under a common rotational offset, while sign-based aspects and sign-conditioned eligibility can change with the zodiac labels. A comparison must distinguish angular separation from rules that depend on named signs or houses.

Practical use
What to do with this answer
Retain angular geometry separately from sign relationships, orb policy, applying or separating state, and tradition namespace. This reveals which part of an apparent disagreement is arithmetic and which is interpretive.
Distinctions to preserve
- Angular separation versus sign-based relationship
- Orb convention versus exact angle
- Shared geometry versus frame-specific eligibility
Limitations
- Aspect terminology and allowable orbs vary by tradition.
- Geometric agreement is not evidence of predictive meaning.

Which existing contracts carry the answer
These linked pages carry the underlying definition, method, or tradition record and its own sources. This page preserves their boundaries rather than becoming a new source of independent authority.
Aspect geometry and orb conventions →
Establishes: An aspect is a classification of the shortest angular separation between two chart points relative to a selected exact angle and allowable orb.
Boundary: An aspect’s presence does not establish its traditional meaning or predictive value.
Applying and separating aspects →
Establishes: An aspect is applying when the selected signed phase is approaching its exact angle under the bodies’ relative apparent motion; it is separating after the crossing.
Boundary: Applying status does not by itself make an interpretation stronger or an event more likely.
Angular aspects versus sign-based aspects →
Establishes: Subtracting the same ayanāṁśa from both points preserves their angular separation. A 180-degree opposition remains 180 degrees in either consistently transformed frame.
Boundary: Do not count the same angular separation twice as corroboration or translate one tradition’s aspect doctrine into another without an explicit sourced rule.
