In Human Design, the Moon is one of the 13 planetary activations used in the BodyGraph calculation and the fastest-moving planetary body used in the system, completing a full cycle through all 64 Gates approximately every 28 days. The Moon's speed makes it a key factor in daily transits — Ra Uru Hu's "global weather" — and it is the primary planetary influence for Reflectors, whose Strategy involves waiting through a full Lunar Cycle (approximately 28 days) before making significant decisions. On the Design (Unconscious) side, the Moon governs Gravity and Shape — the primal driving force that gives the physical vehicle its form attributes, shape, and fundamental drive through life. On the Personality (Conscious) side, the Moon governs Focus and Drive — what the mind finds compelling, interesting, and worth directing attention toward. Lunations (New Moon, Full Moon) and the Moon's daily position through the Gates are significant factors in transit work.
