Quadrantine Lunation

Definition

A Quadrantine Lunation is an older astrological term for a quarter phase of the lunar cycle, when the Moon forms an approximate 90-degree square with the Sun. It may refer to either the waxing first-quarter Moon or the waning last-quarter Moon. Terminology varies among traditional sources, so the intended phase should be confirmed from context.

Astrological Meaning

Astrologically, the solar-lunar square represents tension between conscious direction, symbolized by the Sun, and immediate needs, habits, or responses, symbolized by the Moon. The waxing quarter is commonly associated with building momentum, testing intentions, and taking action after a New Moon. The waning quarter is more often linked with reassessment, release, and adjustment before the next New Moon. In a natal chart, the phase describes the relationship between the Sun and Moon rather than overriding their signs, houses, dignity, or other aspects.

Why It Matters

The Quadrantine Lunation helps place a chart within the broader lunar cycle. Traditional and modern astrologers may use it to refine interpretations of temperament, timing, or the development of a matter. Its square symbolism can suggest productive friction and a need to respond to changing circumstances, but it does not guarantee conflict or a particular event. Accurate interpretation depends on whether the phase is waxing or waning and on the surrounding chart conditions.
