Gap (갑) and Gi (기) Day Master Compatibility
A rare, magnetic pairing
Gap (갑) and Gi (기) 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. Gi (기), by contrast, is traditionally read as the garden soil — nurturing, practical, and quietly productive — a supportive cultivator who makes others flourish.
Gap (갑) and Gi (기)'s Day Masters form what Saju tradition calls a "stem combination" (천간합) — a pairing that's traditionally read as an unusually strong pull between two people, as if the two elements were drawn to combine into a third (Earth).
This kind of pairing tends to show up as an intense, almost effortless sense of connection early on. Traditionally it's seen as a double-edged tendency: the same pull that makes the relationship feel easy can also make both people lose a bit of their own footing, so it may be worth each person keeping their own interests alive alongside the relationship.
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.
