In astrology, a Grand Cross is an aspect pattern formed when four planets or other chart factors are arranged so that they create two opposing pairs, with the points also connected by approximately 90-degree square aspects. The configuration forms a large cross within the chart and may concentrate considerable activity, tension, or competing demands among the participating factors. Grand Crosses often involve signs of the same modality, such as Cardinal, Fixed, or Mutable signs, which can further shape how the pattern is interpreted. Its meaning depends on the planets, signs, houses, modalities, and overall chart context involved, and it should not be treated as automatically difficult or unfavorable.
