Four Pillars of Destiny, for the curious abroad
Saju (사주) is the East Asian art of reading your four pillars — year, month, day, and hour of birth. Here it's free to read, and free to wish. If it moves you, you may leave a small offering afterward — never required.
Read your saju. Make a wish.
The Wishing Lantern
In Korea and across East Asia, paper sky lanterns (풍등) are released to carry a hope skyward — the warm air inside lifting both lantern and wish. Write yours below.
Your wish is somewhere over the rooftops now.
It joins the others drifting quietly above — see them scattered in the sky here.

Your Four Pillars
Saju is built from four exact coordinates in time: the year, month, day, and hour you were born. If you don't know your birth hour, that's alright — we'll read the three pillars we can.
궁합 · Compatibility
Saju compatibility (궁합) reads how two people's day masters and zodiac signs interact — where you naturally reinforce each other, and where the friction lives. Enter both birth dates below; nothing leaves your browser.
A short guide
A few honest answers to the questions people usually have before or after their first reading.
Saju (사주, "four pillars") is a Korean system, rooted in centuries-old Chinese calendrical astrology, for reading someone's temperament and life pattern from the exact moment they were born — the year, month, day, and hour, each translated into a pair of Chinese characters (a "stem" and a "branch") drawn from a 60-step cycle. Those eight characters together are your 사주팔자 — "four pillars, eight characters."
Unlike Western astrology, which anchors everything to the Sun's position in the zodiac, Saju is built on Chinese Five Element theory (오행: Wood, Fire, Earth, Metal, Water) and how those elements generate, feed, or restrain one another across your eight characters. A reading is really an exercise in balance-reading: which elements are strong, which are missing, and what that pattern tends to produce.
It helps, but it isn't required. Your birth hour determines only one of the four pillars — the "hour pillar," which traditionally colors your later years and your children. The year, month, and day pillars (which carry most of the reading: your Day Master, your element balance, your Ten Gods, your 대운 life-decades) all come from your birth date alone.
If you don't know your birth time, leave it blank here — you'll still get a full three-pillar reading, just without the hour-pillar layer. It's genuinely worth asking a parent or checking a birth record if you can, though: the hour pillar is also what most affects your Day Master strength calculation, so an exact hour sharpens everything else too.
Western astrology reads a single moment against the zodiac's twelve signs and the positions of the planets. Saju reads four moments at once — year, month, day, hour — each rendered as a pairing from a 60-step cycle, working out to 518,400 possible eight-character charts in total (more on that math in the articles below). It's less "which sign are you" and more "what is the elemental weather of the exact hour you arrived."
The other real difference is emphasis: Saju spends most of its attention on your Day Master (the stem of your day pillar) — a single character meant to represent your innate self — and on how the other seven characters support, drain, challenge, or feed that one. Everything from your favorable element to your luck cycles (대운) is read relative to that anchor.
Your Day Master (일간) is the heavenly stem of your day pillar — one of ten possible characters, each carrying an element (Wood, Fire, Earth, Metal, or Water) and a polarity (Yang or Yin). It's treated as the closest thing Saju has to "you": not your whole chart, but the character everything else in the chart is read against.
From your Day Master, a reading derives your Ten Gods (십성) — how each of your other seven characters relates to you (as a peer, an output, a wealth source, an authority, or a support) — and your Day Master strength (신강/신약), a rough read of whether your chart is self-sufficient or leans on its surroundings. That strength reading is what determines your 용신, or favorable element: the one thing this specific chart benefits most from leaning into.

The quick guide above answers the basics. These go deeper — into the math, the mechanics, and the honest limits of what a chart can tell you.
Saju feels intensely personal — eight characters drawn from the exact instant you arrived, unlike anyone else's. Run the numbers, though, and the picture gets a little more humbling: there are only 518,400 possible eight-character charts, total.
Wood, Fire, Earth, Metal, Water — the elements aren't just five separate labels, the entire system runs on how they generate and overcome each other. And your "favorable element" isn't simply whichever one you're missing.

복채 · Bokchae
In Korea, it's tradition to leave a small bokchae — literally "fortune payment" — for a reading, not because it's demanded, but as a gesture of respect for the time and the telling.
Your reading and your lantern are free either way. If either one gave you something worth keeping, you're welcome to leave what feels right.
