This are the astrological aspects based on number 30:
- semiquincile [or semiquindecile]: A30 = 12º
- (hepta)semiquincile [or (hepta)semiquindecile]: 7·A30 = 84º
- (undeca)semiquincile [or (undeca)semiquindecile]: 11·A30 = 132º
- (treci)semiquincile [or (treci)semiquindecile]: 13·A30 = 156º
The semiquincile [or semiquindecile] aspect (harmonic 30) belongs to the family of aspects of cultural self-organization (harmonic 5), which derive from the division of the circle (360º) by the number 5, such as the quintile (harmonic 5), the decile (harmonic 10), the quincile [or quindecile] (harmonic 15) and the quinvigintile (harmonic 25).
To understand better its meaning, the number 30 can be decomposed into 5 * 6, because in that way it shows the combination of the quality of cultural self-organization of the number 5 (quintile) with the quality of synchronization and opportunity of the number 6 (sextile). It can also be decomposed into 10 * 3, combining the quality of gradual formation of the number 3 (trine) with the quality of bifurcation and transformation of the number 10 (decile).
The number 30 (semiquincile [or semiquindecile]) is related with a series of actions that are carried out in different areas, but all oriented in the same direction, whose global self-organization creates an opportunity of great importance.
