Korean four-pillars astrology calculator with full birth-chart analysis, 60-pillar interpretations in Korean and English, daily luck, compatibility check.
In Korean Saju astrology, the day you were born maps to one of 60 'Day Pillars', each a vivid archetype — like a great tree finding a deep well, or a flower enduring cold earth. I translated all 60 into English with full readings. Find yours free: https://tarofortune.pythonanywhere.com/en/sixty-pillars?ref=lemmy #astrology #Saju #BaZi #FourPillars #ChineseAstrology
Coming from Western astrology to Saju, the mental model shift:
Western — where the planets were when you were born. Saju — the 'energetic signature' of your birth moment, expressed as 8 Chinese characters.
Saju uses Heavenly Stems (10) and Earthly Branches (12) forming 60 cycles. Birth year, month, day, and hour each get one stem + one branch — '4 pillars / 8 characters.'
Biggest practical difference: your day pillar functions like a sun sign in Western. Different day pillars produce strikingly different archetypes.

The Sun's apparent ecliptic longitude is divided into 24 equal segments of 15°. Each crossing is a 'solar term' — observable to ancient astronomers via shadow length and equinox/solstice timing.
In BaZi/Saju, 12 of the 24 solar terms mark month-pillar boundaries:
Two people born 2 days apart in early February can have entirely different month pillars if the boundary fell between them.

The 12 animals map to the 12 Earthly Branches:
Rat=子 | Ox=丑 | Tiger=寅 | Rabbit=卯 Dragon=辰 | Snake=巳 | Horse=午 | Goat=未 Monkey=申 | Rooster=酉 | Dog=戌 | Pig=亥
'I'm a Tiger' = your YEAR branch is 寅. But you also have month, day, hour branches — three more 'animals.' Your zodiac year is just 1 of 4.

Korean parents sometimes check kids' Saju to guide parenting:
Used this way, Saju is just typology + timing — like MBTI parenting books.

Every Heavenly Stem comes in Yang or Yin. Same element, different expression style.

Saju and BaZi inherit 'special spirits' (神煞 Shensha) — symbolic labels for specific stem-branch combinations:
Modern scholarly practice is split. Pro-Shensha: accumulated empirical observations. Anti-Shensha: late additions with weaker theoretical grounding than Ten Gods or Yongshen.
My take: useful as tie-breakers. Not load-bearing.

If you've ever come across BaZi or Saju and wondered what the "60 day pillars" actually are — here's a free reference with all 60 listed, one per archetype:
https://tarofortune.pythonanywhere.com/en/sixty-pillars
Each pillar has a heavenly stem (10 options) and earthly branch (12 options), but only 60 of the 120 combinations are valid because of the rotation cycle (the sexagenary cycle).
Example: Day Pillar #50 is Gye-Chuk (癸丑), "water on top of earth" — typically read as ambition meets caution.

Most 'Saju compatibility' content online reduces to 'X zodiac is compatible with Y.' That's the bottom 5% of what real analysis looks at.
Full analysis:
Day Master union (天干合) — 5 stem-pair fusions: Jia-Ji, Yi-Geng, Bing-Xin, Ding-Ren, Wu-Gui. Strongest 'attraction' factor.
Day Master Five-Element relationship — Productive, Restraining, or Same.
Day Branch union or clash (六合/沖) — Six pair-unions bring ease; six clashes create friction.
Year-Branch relationship (zodiac) — Social-side rhythms; least weighted.

The year boundary in Saju/BaZi isn't Jan 1 — it's the solar term Ipchun (立春), around Feb 4. Precisely the moment the Sun's apparent ecliptic longitude reaches 315°.
Most online 'free' Saju readers approximate this as 'Feb 4 00:00' — wrong by up to 24 hours, which flips year pillars for anyone in the window.
Correct way: Meeus astronomical algorithm — compute apparent solar longitude from Julian Day, iterate to find exact crossing.

5+ of the same element out of 8 is extreme. Called 'one-sided' (편중) charts.
Two paths:
Most extreme charts are just lopsided personalities needing conscious development of missing elements.

Saju is the Korean four-pillars astrology system. Given a birth date + time, it produces a 4x2 grid: year/month/day/hour x heavenly stem/earthly branch. The Day Pillar (one of 60 combinations) is the personality archetype - like a 60-fold zodiac.
I built a free, no-signup calculator: https://tarofortune.pythonanywhere.com/ (Korean) / https://tarofortune.pythonanywhere.com/en (English).
What it does:
Stack: Flask + Pillow for dynamic OG card generation. Calculator uses Meeus astronomical algorithms because solar terms (jeolgi) shift month-pillar boundaries - a calendar-day approach gets it wrong about 12 times a year.
No database. No accounts. No email collection. Just numbers in, interpretation out.
Source closed for now; happy to discuss the algorithm if anyone is curious.
Most popular content = personality. Other half = timing analysis.
Tools:
Use for timing major decisions to favorable windows. NOT 'you'll marry this year' but 'this year supports stabilization of close relationships.'

Studying Saju for a year — the day pillar concept feels like a higher-resolution version of sun signs.
Western has 12 sun signs. Saju has 60 day pillars — each a distinct archetype combining Heavenly Stem (10) and Earthly Branch (12).
