Four Pillars

Your birth date and hour, read as the Four Pillars — your zodiac animal and inborn balance

If you don't know the exact hour, use your best estimate — it only shifts the Hour Pillar, not your year, month, or Day Pillar

Needed for the Luck Pillars (大運) — the traditional rule parts which way they run by gender. Leave it unset and everything else still comes out. Like your birth details, it is saved only on this device.

Calculated from your exact birth date and hour using the traditional Chinese sexagenary (stem-branch) calendar — a fun exploration of Four Pillars (BaZi) astrology, not a professional reading.
