What exactly is saju?

A Korean classical 명리학 system that maps year/month/day/hour to the ten-stem and twelve-branch cycles, producing eight characters — hence "사주팔자".

Is this calculation accurate?

Uses the standard Korean Lunar Calendar conversion + 24 solar-term month pillars — the same algorithm as commercial saju apps. Scores are generalized estimates.

How is the K-pop compatibility score computed?

Day-stem vs day-stem: five-element generation (+30) / destruction (−20), then twelve-zodiac harmony/conflict (±10), normalized to 0–100. Hour pillars dropped because celebrity birth times are private.

Are the 14 languages human-reviewed?

EN/KO/JA/ZH are human-reviewed; the rest are LLM-translated and may be slightly off.

Should I take this seriously?

It is entertainment built on a Korean cultural tradition. Do not use the output for medical, legal, or financial decisions.

Korean Saju Reading

Open the tool

About this tool

Korean Saju Reading (saju) converts a date and time of birth into the four-pillar 사주팔자 using Korean ten-stem / twelve-branch / five-element / twelve-zodiac classical 명리학. It returns a fortune score, K-pop celebrity compatibility (built on a 1,000-artist public-birthdate dataset and the five-element generation/destruction + twelve-zodiac harmony/conflict rules), and wealth fortune (lucky color, direction, and 6 lottery numbers). Uses the Korean Lunar Calendar + 24 solar terms, ships 14-language UI (en/ko/ja/zh/vi/id/th/fr/es/de/pt/ru/hi/ar), and exports 1080×1350 Instagram-story PNG cards. All math runs in the browser; birth data never leaves the device.

Use cases

Scenario 1

First saju for a K-drama fan abroad

A new K-culture fan tries saju in their native UI (EN, VN, TH, etc.) and shares the 1080×1350 result card to their Instagram story.

Scenario 2

K-pop bias compatibility

Pick a favorite idol from the 1,000-artist database and get a 0–100 compatibility score (Soulmate / Sparkle / Mellow / Tense / Distant) from five-element + twelve-zodiac rules.

Scenario 3

Today’s lucky color and lottery numbers

In Wealth mode, get today’s lucky direction, color, and 6 lottery numbers — light, daily entertainment built on classical saju.

Scenario 4

Saju with unknown birth time

Users who don’t know their birth time pick "Unknown" — the tool drops the hour pillar and runs a 3-pillar calculation at ~75% precision.

Scenario 5

Global SNS traffic anchor

K-pop fandom and K-content creators share the 14-language saju card with their local fans as a K-culture gateway.
