Reference, not advice

This is cultural and astronomical reference, not personal prediction or advice.

Major (Ptolemaic) aspects are documented in Claudius Ptolemy's Tetrabiblos (2nd c. CE). Quintile and biquintile were added by Johannes Kepler in Harmonices Mundi (1619). Default orbs follow classical Western convention.
