Your Day Master (일간) is the most important character in your saju chart — your core self, one of 10 archetypes. Put two people together and their Day Masters form one of 55 possible pairings, each with its own classical reading: five of them are the famous Heavenly Stem combinations (천간합), some flow along the generation cycle (상생), some press along the control cycle (상극), and some mirror each other inside a shared element.
