Four Pillars of Destiny Calculator
The Four Pillars of Destiny — BaZi in Chinese — read your birth moment as four stem-and-branch pairs. Same engine as our BaZi calculator, explained in Western terms.
Four Pillars of Destiny and BaZi name the same four-part birth chart; this page keeps the common English vocabulary while using the same visible time-correction receipt as the BaZi calculator.

Awaiting your birth details
HOUR BRANCH SHIFTED · CHOU → ZI — clock time and solar time fall in different branches; the corrected one is used.
Four Pillars vocabulary, mapped
Day Master (日主) — your day stem, the self-point of the chart. Ten Gods (十神) — the ten functional relationships other stems hold to your Day Master, such as Direct Wealth or Seven Killings. Luck Pillars (大运) — ten-year cycles that sequence your chart through time.
Use this page when you searched in English
This page owns the Four Pillars of Destiny calculator wording. The BaZi calculator owns the transliterated BaZi wording. Both open the same deterministic chart engine; neither page translates into a different calculation method.
Before reading any interpretation, compare the displayed year, month, day and hour pairs. If another calculator produced different pillars, use the six-step calculator-disagreement audit to locate the first changed input, clock correction or boundary rule.
Why true solar time is not optional
The hour pillar follows the sun. Clock time can sit tens of minutes away from solar time depending on your longitude and the season — enough to change the hour pillar. We correct for it and show the math.
For example, 12:00 civil time in Toronto on 20 July 2026 resolves to about 10:35:59 at the city-center coordinates. That moves the hour branch from Wu (Horse) to Si (Snake), while a birth well inside a branch may not change at all.
