A saju chart is eight characters arranged in four columns, and to a newcomer it looks like a wall of hanja. Practitioners, though, read it in a fairly standard order. Follow the same five steps and the wall turns into a map.
Step 1 — Find yourself: the day master
Look at the day pillar’s top character. That’s the day master (ilgan, 日干) — the character that represents you. Everything else in the chart is read in relation to it. Day masters come in ten flavors: five elements (wood, fire, earth, metal, water), each in a yang or yin form. A 甲 (yang wood) person and a 乙 (yin wood) person are both “wood,” but tradition pictures the first as a tall tree and the second as a climbing vine — same material, different strategy.
Step 2 — Read the four pillars as life areas
Each pillar traditionally maps to a domain and a season of life:
| Pillar | Traditional domain | Life phase |
|---|---|---|
| Year | Ancestry, roots, first impressions | Childhood |
| Month | Parents, career environment | Youth |
| Day | Yourself; the branch = spouse/partner | Adulthood |
| Hour | Children, ambitions, output | Later years |
This is why the month pillar gets so much attention in career questions, and why the day branch — the “spouse palace” — comes up in compatibility readings.
Step 3 — Check the element balance
Count the five elements across all eight characters (our chart does this for you, including the hidden stems inside each branch). You’re looking for the shape of the mixture: What dominates? What’s missing entirely? A chart with four fire characters reads very differently from one with none. Missing elements aren’t “bad” — they mark themes that take conscious effort rather than coming naturally.
Step 4 — Meet the ten gods
Here’s where saju gets its real grammar. Every character is classified by its relationship to your day master into one of ten categories — the ten gods (sipseong, 十星): peers, output, wealth, authority, and resource, each in a yang/yin pair. Despite the dramatic name, no deities are involved; they’re relationship labels. “Wealth” characters are the elements your day master controls; “authority” characters control it; “resource” characters feed it. The pattern of which gods appear — and where — is what turns eight characters into a story about drive, career, and relationships.
Step 5 — Add time: the luck cycles
The natal chart is the static layer. Over it runs the daeun (대운) — ten-year luck pillars that shift the chart’s balance decade by decade — plus yearly and monthly cycles. This is the layer Korean readers usually mean when they say a year “opens up” for someone. The chart doesn’t change; the weather around it does.
