About FateHive and our sources

• Gregorian-to-lunar conversion and the Day Pillar use an open-source Korean calendar library (@fullstackfamily/manseryeok).
• The Year and Month Pillars are set by calculating the Sun’s ecliptic longitude to find the exact moment of each solar term, so dates near Lichun and other boundaries are handled to the minute.
• Birth time is corrected for the difference between standard time and true solar time (about 32 minutes, using Seoul as the reference) and for Korean daylight-saving periods (1948–1960 and 1987–1988).
• Births around midnight follow the late-Rat-hour (yazi) rule: the day changes at midnight. Other Saju apps may differ on this point.
• Day Master strength and the Useful God are simplified judgments. Very special chart structures are not modeled.

• I Ching: the hexagram texts are based on the public-domain classic Zhouyi (Chinese Wikisource). Our English translations, explanations and plain summaries are our own writing.
• Tarot: card images are from the Rider-Waite-Smith deck (1909), a public-domain work (via Wikimedia Commons). Card meanings are written from standard Rider-Waite tradition.
• Dream meanings: there is no single authoritative source. We combine Korean folk belief, labeled as such, with psychological perspectives.
• Horoscopes and compatibility: generated by rules from Chinese zodiac relationships and the Moon’s position, not copied from other sites.

Every reading is for entertainment and self-reflection. The same chart can read differently between schools, and none of this is a sound basis for health, legal, financial or relationship decisions.

Unfamiliar words are explained in the glossary.
