What does the Jeong-Sa day pillar mean?

Jeong-Sa (丁巳) is Yin Fire over the Snake: an intense, quick and ambitious nature with a bright mind and a competitive edge.

How do I know if Jeong-Sa is my day pillar?

The day pillar comes from a sixty-day cycle and from true solar time at your birthplace, so it cannot be worked out from your birth year or zodiac animal. Calculate your chart: if the Day column shows 丁巳, this is your pillar.

What is 丁巳 called in Chinese BaZi?

Ding Si. It is the same pillar. Korean Saju reads the characters as Jeong-Sa and calls it Jeongsa ilju (정사일주); BaZi sources write Ding Si in pinyin.

It thinks fast and expects others to keep up.
