Free calculators based on classical formulas — no login. Each tool explains when to use it.
Feng Shui (Compass)
Ming Gua Calculator
Birth year & gender → East/West group & lucky directions
What it's for：For Ba Zhai (Eight Mansions): find your life Gua group and auspicious directions (Sheng Qi, Yan Nian, etc.). Use when choosing homes, bed head, desk facing, or office seat.
House Gua · Ba Zhai Sectors
Sitting direction → house Gua & eight sector ratings
What it's for：From the house sitting direction, get the house trigram and four auspicious / four inauspicious sectors. Use to assess door, master bedroom, and kitchen placement.
Person–House Match
Life Gua + house Gua → compatibility
What it's for：When buying, renting, or sharing a home: see if your Ming Gua matches the house group (East/West). If not, prioritize your personal lucky directions for bed and desk.
24 Mountains Lookup
Compass degrees → mountain name & palace
What it's for：Convert luopan readings into the 24 mountains and bagua palaces — the foundation for Flying Stars and Ba Zhai. Works with the phone compass tool.
Three Cycles Nine Periods
Build/move-in year → current Period & element
What it's for：Identify which Period the property belongs to (e.g. Period 9, 2024–2043) and dominant stars/elements before renovation or activation.
Flying Star Chart (Basic)
Sitting degrees + build year → period & mountain/water stars
What it's for：With exact sitting and build year, view period chart and mountain/water stars for wealth and health sectors. Full 120-fenjin替卦 requires professional luopan.
Annual Afflictions
Year → Tai Sui, Five Yellow, Two Black positions
What it's for：Before renovation, ground-breaking, or moving bed: see which sectors are afflicted this year. Avoid digging, noise, and red fire activation in those areas.
Direction vs Annual Sha
Year + direction → clash with Tai Sui, Five Yellow, etc.
What it's for：Quick check if a planned sector (e.g. NW renovation, bed head direction) conflicts with annual afflictions for that year.
Ba Zi (Four Pillars)
Zodiac · Year Pillar & Nayin
Birth date → year stem-branch, zodiac, Nayin element
What it's for：Basic Ba Zi entry: year pillar, Chinese zodiac, and Nayin five-element of birth year. Choose Lichun or calendar year boundary.
Four Pillars Chart
Birth date & hour → year, month, day, hour pillars
What it's for：Generate a simplified four-pillar chart and day master (day stem). Month pillar uses approximate solar terms — use an almanac for precision.
Zi Wei Dou Shu Chart
Birth date & hour → twelve palaces, stars, mutagen
What it's for：Build a Zi Wei chart (iztro) with soul palace stars, palace layout, and decadal ranges — starting point for Purple Star readings.
Day Master Element
Birth day → day stem element & brief traits
What it's for：Focus on the day stem (日元) five element as the core of your chart. For full favorable element analysis, combine with month and full chart — or ask AI consultation.
Date Selection · Auspicious Days
Date range + activity → Jianchu, clashes & picks
What it's for：Before move-in, ground-breaking, wedding, or signing: scan a date range for relatively auspicious days using Jianchu twelve officers, Tai Sui / month clash, Three Killings, and optional annual direction afflictions.
