Q: How does the calculator handle Solar Terms, Late Zi hour, and Southern Hemisphere births?

The engine computes exact astronomical solar longitude: the Year Pillar changes at Beginning of Spring (Li Chun) rather than Lunar New Year, and each Month Command switches at the exact minute of its solar term. Under Special Cases, you can toggle Late Zi (23:00 to 00:00) next-day Day Pillar handling, Southern Hemisphere seasonal Month Command inversion, or manual Stem and Branch selection for boundary births.

Is casting a Four Pillars of Destiny (BaZi) chart free?

Yes. Entering your date and hour of birth immediately casts your complete Four Pillars chart for free, including Heavenly Stems, Earthly Branches, Hidden Stems, Ten Gods, Symbolic Stars, Five Elements percentages, Eight Mansions Life Gua, 10-year Luck Pillars, Annual Pillars, and a preliminary reading letter. Coins are only used when you choose to unlock optional in-depth chapters.

How does the calculator handle Solar Terms, Late Zi hour, and Southern Hemisphere births?

The calculation engine tracks exact astronomical solar longitude: the Year Pillar changes at Beginning of Spring (Li Chun) rather than Lunar New Year, and each Month Command turns at the exact minute of its solar term. Under Special Cases & Boundary Settings, you can configure Late Zi (23:00 to 00:00) Day Pillar advancement, Southern Hemisphere 6-month seasonal Month Command inversion (derived via Five Tigers Escaping), or manual Four Pillars selection for boundary births.

How does a BaZi solar-term monthly forecast differ from a Purple Star monthly forecast?

Purple Star Astrology tracks lunar months across the twelve palaces, whereas BaZi monthly fortune follows the 12 solar-term months (starting from Beginning of Spring in Yin Tiger month), analyzing which Ten God and elemental interaction the month's Stem and Branch form against your Day Master and Useful God.
