General-purpose AI answers can change with the prompt and may not disclose their calendar convention. FateAIverse calculates the chart first with documented rules, then uses AI only to explain the calculated result.
Calculation method: documented rules and stored calendar data. Solar-term boundaries: per-year data for the supported range. Lunar leap-month input: explicit calendar fields. Repeatability: the same inputs produce the same chart. Interpretation: calculated chart plus clearly labeled AI explanation.
Boundary example: for a birth on February 3, 1990, the service applies the stored Ipchun date for that year instead of a single fixed-date approximation.
1. Enter Birth Data — Name, birth date (year/month/day), birth time if known, and gender.
2. AI Calculates — The AI looks up your exact Manseryeok data, including solar term boundaries.
3. Read Your Chart — Get Four Pillars, Day Master, Five Elements, Yongshin, and life cycle analysis.
The Four Pillars of Destiny (四柱八字, BaZi or Saju) is an ancient Chinese and Korean astrology system that analyzes your fate based on the year, month, day, and hour of birth. Each 'pillar' consists of a Heavenly Stem and Earthly Branch, forming a unique 8-character chart.
Enter your birth year, month, day, and time into the FateAIverse calculator. The AI converts your Gregorian birth date to the traditional lunar/solar calendar (Manseryeok) and calculates your exact Four Pillars, including the correct Year Pillar based on actual solar term (Jeolgi) dates.
The Day Master (日干) is the Heavenly Stem of your Day Pillar and represents your core personality. There are 10 Day Masters corresponding to the Five Elements: Wood (甲乙), Fire (丙丁), Earth (戊己), Metal (庚辛), and Water (壬癸).
FateAIverse uses a stored Manseryeok dataset and a documented calculation pipeline for supported dates. The same inputs produce the same chart, but users near a solar-term boundary should still verify the date, time, calendar type, and timezone they entered.
