Day master compatibility: all 55 pairs
Your day master is the top character of your birth day, the one saju reads as “you.” There are ten of them, from Yang Wood (甲) to Yin Water (癸). This chart compares two day masters using the same fixed tables for every pair: the five-element cycle, the five stem combinations and the four stem clashes.

How two elements meet
Feeding cycle: Wood feeds Fire, Fire makes Earth, Earth holds Metal, Metal carries Water, Water grows Wood. The one who feeds tends to give; the one fed tends to receive.
Checking cycle: Wood breaks up Earth, Earth dams Water, Water puts out Fire, Fire melts Metal, Metal cuts Wood. The one who checks tends to steer; the one checked tends to feel pushed or shaped.
Same element: two of a kind. Easy understanding, plus a little rivalry over the same space.
The five stem combinations
甲己 makes Earth, 乙庚 makes Metal, 丙辛 makes Water, 丁壬 makes Wood, 戊癸 makes Fire. A combination is read as a strong pull between two people, the kind that makes them want to team up.
The four stem clashes
甲庚, 乙辛, 丙壬 and 丁癸 face each other from opposite sides. A clash is read as two different rhythms. It brings energy and friction, and it does not decide whether a couple lasts.
Questions about this pair
What is a day master?
In saju (Korean Four Pillars), your birth date and time become eight characters. The top character of your birth day is your day master. It stands for you, so compatibility readings usually start by comparing two day masters.
Which day masters are most compatible?
By the tables, the five combination pairs (甲己, 乙庚, 丙辛, 丁壬, 戊癸) are the strongest pull, and feeding pairs tend to feel supportive. Still, the day master is one character out of eight, so no pair is good or bad on its own.
How do I find my day master?
You need your birth date (and time if you know it). Enter it in the free saju card and your day master is the top character of the Day column.
Is day master compatibility the same as zodiac compatibility?
No. Zodiac compatibility compares the animal of each birth year. Day master compatibility compares the character of each birth day, which saju treats as the person themselves.
