What is a BaZi chart?

A BaZi chart (also called Four Pillars of Destiny or 生辰八字) converts your year, month, day, and hour of birth into four pairs of heavenly stems and earthly branches. DEEP ORACLE provides a free online BaZi chart calculator that corrects for true solar time, renders the full chart, and drafts an AI BaZi chart interpretation.
