What is Saju? 四柱
Saju means "four pillars." For over a thousand years Koreans have read the moment of birth not as a sky full of planets but as a calendar: the year, month, day and hour, each written as a pair of characters. Eight characters in total — the palja (八字) — every one of them an element: Wood, Fire, Earth, Metal or Water.
How the chart works
The most important character is the stem of your day pillar, the Day Master (일간). Western astrology has the Sun sign; Saju has this. Everything else in the chart is read in relation to it — which elements feed it, which ones drain it, which ones it controls.
In Korea this isn't fringe. It's what your mother checks before your wedding, what a founder checks before a launch date, and what has lines out the door at saju cafés in Seoul every New Year.
Who's reading your chart
I'm Mina. I grew up in Incheon, Korea, where a chart gets pulled before a wedding, before a move, and before at least one job offer. I started reading for friends, then for strangers, then for people who found me online. Daymaster is where I do it in English.
I read the way it's done in Korea: your birth hour corrected to true solar time, all eight characters together instead of one sign, and the ten-year cycles that say where you are right now. Every paid reading is written for one chart and never reused.

Yang Metal, three Earth, no Fire. My own reading says I over-prepare and carry problems that aren't mine. It isn't wrong.
Go deeper than the Day Master.
The free result above is the first line of your chart. A full reading is written for you, from your exact eight characters, and delivered as a PDF to your inbox.
Your clock time is not your birth time.
A Korean reader never uses the hour on your birth certificate as is. It gets corrected to true solar time: daylight saving removed, then adjusted for how far east or west your birthplace sits in its time zone. Every paid reading does this from the city you give us.
Same person, a different hour pillar: a quarter of the chart. The PDF shows the time it used and how it got there.
What a reading picks up on
- Why you look decisive but second-guess everything in private
- The difference between handling pressure and losing control over how you work
- Why mixed signals feel like a puzzle you're supposed to solve
- What you need from a relationship, in words you can actually use

Questions
Is this the same as Chinese BaZi?
Same root, same eight characters. Saju is the Korean tradition that grew from it — the way it's read, the emphasis on the Day Master and on luck cycles, and its place in everyday life are distinctly Korean.
I don't know my birth time. Does it still work?
Yes. You'll get three of the four pillars — year, month and day — and your Day Master comes from the day, so it's unaffected. The hour pillar adds detail about later life and children; without it we simply leave that column blank rather than guess.
Why is my year animal different from the Chinese zodiac?
Saju switches years at Ipchun (입춘), the start of spring around February 4 — not at Lunar New Year. If you were born between Lunar New Year and February 4, your Saju animal is the previous year's.
Born in the US in summer? Your hour column might shift.
The free result above uses the clock time you typed. Paid readings do what a Korean reader does: remove daylight saving time and adjust for your birthplace's longitude to get true solar time. For many US summer births that moves the hour by 1–2 hours, which can change the hour column. Your Day Master (the day column) almost never changes.
Who writes the paid readings?
