Each term marks 15° of the sun's ecliptic position. Korean Saju determines monthly pillar by solar term — so zodiac uses Lichun start, monthly fortune uses individual terms.
24 markers dividing the ecliptic into 15° segments — capturing the sun's position across the year. Foundational rhythm of East Asian agrarian life. In Korean Saju the monthly pillar (月柱) is set by these terms.
Each zodiac has an element (e.g. Horse = Fire) and each term has an element (e.g. Lichun = Wood). We map their generation/control relationships: same element = boost, generation = good, control = caution. 288 auto combos.
Traditional 5-element correspondence (Wood = green/3·8/East, Fire = red/2·7/South, Earth = yellow/5·10/Center, Metal = white/4·9/West, Water = black/1·6/North) + zodiac sub-element correction.
