☯︎BaZi Four Pillars · Zi Wei Dou Shu

BaZi runs on the sexagenary calendar: the sixty-cycle of stems and branches was already dating days on Shang oracle bones three thousand years ago, and has run unbroken since. Li Xuzhong of the Tang read fate from three pillars; in the tenth century Xu Ziping added the hour and centred the day stem, and the art has carried his name ever since. Classics from the Yuanhai Ziping to the Di Tian Sui stacked commentary on commentary, and by the Ming and Qing it was in use from court to street.

It converts a birth moment into eight characters and reasons about strength and balance through five-element logic. Calendar algebra with explicit rules, not fortune slips.

Zi Wei Dou Shu is traditionally attributed to the tenth-century Daoist Chen Tuan, and took its settled form in the Ming-era Complete Book of Zi Wei Dou Shu. Instead of five-element algebra it divides the chart into twelve palaces, seats the stars led by Zi Wei palace by palace, and drives decades and years through the four transformations.

Palace by palace, item by item, it has long been ranked alongside BaZi as the other great Chinese system of fate calculation.

Common questions

What is BaZi (Four Pillars)?

The Chinese system that encodes your birth year, month, day, and hour as four pairs of heavenly stems and earthly branches, eight characters in total. Reading them is elemental accounting: which of the five elements you have in excess, and which you lack.

What is the Day Master?

The heavenly stem of your day pillar, taken as you in the chart. Whether it is strong or weak against the season and the other seven characters decides everything downstream, including which elements help you.

What is the favorable element (Yong Shen)?

The element that rebalances your chart: a weak Day Master wants what feeds it, a strong one wants an outlet. Nura derives yours from the engine's strength calculation and uses it to tag which days flow with you.
