四柱

Four Pillars

四柱 · Sìzhù

The four stem-and-branch pairs for the birth year, month, day and hour. Together they form the eight characters of a BaZi chart.

In more detail

A pillar is a calendar pair, not a separate personality type. Year and month boundaries follow solar terms in our chart calculation.

Also called: Four Pillars of Destiny

Together, 四柱 reads “four pillars”.
