Gap (갑) and Gap (갑) Day Master Compatibility
Mirror images
Gap (갑) and Gap (갑) are two of the ten Day Masters used in Saju (Four Pillars of Destiny) astrology. If your Day Master is one and a partner, friend, or coworker's is the other, here's what the traditional Five Element relationship between the two tends to look like.
Gap (갑) is traditionally described as the tall tree — upright, principled, and growth-driven — a natural leader with strong convictions, and a dislike of bending. Two people sharing this same Day Master tend to recognize this quality in each other immediately.
Gap (갑) and Gap (갑)'s share the exact same Day Master. In Saju terms this is read as facing the same direction, with the same instincts and the same blind spots.
This tendency can mean instant understanding — you likely won't need to explain yourselves twice. It can also mean the relationship lacks a natural counterbalance, since neither person tends to compensate for what the other lacks. Traditionally this is read as a comfortable, low-friction match that benefits from consciously bringing in outside perspective.
Curious what this looks like with your actual birth chart? The Saju Compatibility tool on this site calculates both Day Masters from real birth dates and times, along with each person's full Five Element balance.
