Your bias has a birth chart.
So do you.

Your zodiac is 1 of 12. Your Korean birth chart is 1 of 518,400, read down to the hour you were born. We cross-read you and your bias through three systems (Korean Saju, Chinese Ziwei Doushu, and Western astrology) and tell you exactly how you two line up: the spark and the friction, together. No fortune-cookie flattery.

Cast your chart

We only need your birth moment. Nothing leaves your device.

Birth date *

Birth time

:

I don't know my birth time

Name (optional)

Just enter the local time at the place you were born, exactly as the clock showed it. No timezone conversion needed.

Birth city *

Clocks run on a national standard meridian; the sky doesn't. Your birth longitude is what the Hour Pillar is really built from, and the correction is big enough to move it a whole pillar. Not on the list? Nearest larger city is fine.

Daylight saving time

If summer time (DST) was in effect where and when you were born — e.g. summer births in the US or Europe, Korea 1948–60 & 1987–88 — choose Yes. We remove the shifted hour to read the true solar time.

Gender * (sets the direction of your 10-year luck cycles)

What did the dream show?

In Korea, a vivid dream around conception or birth — the taemong — is read as the first portrait of a child. Pick the symbol closest to yours (or the one your mother remembers).

I Ching · The Book of Changes

Ask one question

The I Ching answers situations, not futures — "should I take this" reads better than "will I be rich". You get one cast per question per day: the coins land the same way if you ask the same thing again today, so make it the question you actually want answered.

Runes · The Norn Draw

Ask, then draw three

Elder Futhark — the 24-rune alphabet Northern Europe used for writing and for casting lots. You draw three: Urd (what is already set), Verdandi (what is moving now), Skuld (what is becoming). Nine of the 24 look identical upside down, so those nine can never come up reversed — the ones that do are telling you something has flipped.

Pet Saju · Your Animal's Four Pillars

Read your animal

The same four pillars, run on your pet's birthday. Most people don't know the hour — that's fine, and it's the normal case here. If they were adopted or rescued and the date is a shelter estimate, say so and the reading adjusts what it claims.

Tarot · Situation, Action, Outcome

Ask, then pull three

Full 78-card deck, upright and reversed. Three positions: the Situation, the Action available to you, and the Outcome if you take it. Same rule as the other oracles here — one pull per question per day, so ask the thing you actually want answered.

What Is Saju?

The system behind every reading on this page

Western astrology reads the sky at your birth — which of 12 constellations the sun sat in. Saju (the “four pillars”) reads something more specific: the exact year, month, day and hour you were born, translated into eight characters from a 60-unit cycle of Heavenly Stems and Earthly Branches. Twelve zodiac signs versus 518,400 possible charts — that gap is the whole reason a Saju reading can feel scarily accurate where a horoscope feels one-size-fits-all.

The Four Pillars

Your birth moment produces four two-character pillars — Year, Month, Day and Hour — each pairing a Stem with a Branch. Classical Saju reads them as four seasons of one life: the Year pillar is your roots (childhood, inheritance), the Month is the soil your career grows in, the Day is you — literally, your Day Master — and the Hour is what you build and leave behind.

Stems, Branches & the Day Master

The ten Heavenly Stems and twelve Earthly Branches each carry one of the Five Elements — Wood, Fire, Earth, Metal, Water — in a Yin or Yang polarity. Your Day Master is the Stem of your Day pillar: the one character classical Saju treats as “you.” Everything else in the chart is read around it. It's why this app hands you an archetype like The Great Oak or The Midday Sun instead of a sun sign — that archetype is your Day Master.

Ten Gods, luck cycles & timing

Every other character in your chart plays a role relative to your Day Master — classical Saju calls these the Ten Gods (十神): Wealth, Authority, Resource, Output, Companion. Their balance is what actually drives a career or wealth reading, not just your element. On top of that, Dae-un (大運) — luck pillars that shift roughly every ten years — and Se-un (歲運) — the year you're currently in — layer timing on top of personality: the same chart reads differently at 25 than at 45.

A living tradition, not a museum piece

Saju has been read in Korea for over a thousand years, and it's still exactly how most Koreans check compatibility before marriage, timing before a big move, or just what kind of year is ahead — right alongside their coffee horoscope app. It sits in the same family as Chinese Bazi and shares roots with feng shui, but the way Koreans read it — the archetypes, the Ten Gods framework, the Tojeong New Year almanac — is its own tradition.

None of it is destiny carved in stone. Think of a chart as the weather you were born into — it tells you which winds to expect, not which way you have to sail.
