Core Concepts

Bazi (八字)bā zì
Literally 'eight characters.' The Chinese system of destiny analysis that converts your birth year, month, day, and hour into eight characters (four pillars × two characters each) drawn from the Heavenly Stems and Earthly Branches. Also called the Four Pillars of Destiny.
Four Pillars (四柱)sì zhù
The four columns of a Bazi chart — Year, Month, Day, and Hour. Each pillar contains one Heavenly Stem on top and one Earthly Branch below. Together they encode the elemental state of the universe at your birth moment.
Day Master (日主)rì zhǔ
The top Heavenly Stem of your Day Pillar — the protagonist of the chart and the reference point every other character is read against. Your Day Master's element is the closest thing Bazi has to a Western sun sign.

Life Chapters (大运)dà yùn
Roughly ten-year windows that flow through your life in sequence, each carrying its own two-character pillar and elemental signature. Your natal chart is the hand you were dealt; Life Chapters are the sequence of dealers. Also called Da Yun or Major Luck Pillars.
True Solar Time
The actual position of the sun at your birth location, as a sundial would show it. Differs from clock time by up to ±16 minutes (the Equation of Time) plus a longitude correction. Our calculator applies this automatically using your birth city.
NaYin (纳音)nà yīn
The 'soul resonance' element of a pillar's stem-branch pair. There are 30 NaYin types (e.g. 'Celestial River Water' for 丙午). On this site we render each as a poetic English archetype.

The Five Elements (五行)

Also called Wu Xing. Not substances but five families of energy type, each with its own temperament. They interact through a generating cycle (Wood feeds Fire, Fire creates Earth…) and a controlling cycle (Wood roots into Earth, Earth dams Water…).
