BaZi, or 'Four Pillars of Destiny', describes the moment of birth with four pairs of Chinese signs: year, month, day and hour. Each pair has a heavenly stem and an earthly branch with its own element.

Enter the birth date, time, and place. The birth hour is required: without it, the fourth pillar cannot be calculated.
