Day pillar

Mu-ja · 무자

戊子

The two characters of the day someone was born. They come round every sixty days, and they are the third of the four pillars.

What it is made of

  • The stem Mu (무, 戊) is the yang of Earth.
  • The branch Ja (자, 子) is the yang of Water.
  • Ja carries Gye (계, 癸) inside it. Korean calls these 지장간 — the stems hidden in a branch.
  • The stem's element is the one that governs the branch's.

On the calendar

Ja is the character for the month that opens at Daeseol (Major Snow), and for the hours from 11pm to 12:59am.

It sits 25th in the cycle of sixty. Days run in that order, so the same two characters come back every sixty days.

Days that were Mu-ja in 2027

A day turns at midnight. For a birth between 11pm and midnight, some schools read the next day instead. CELESTRY reads it as the same day by default and lets you choose the other.

A day pillar is not read on its own

The day pillar is one line of a four-line coordinate. Two people can share it and, with the other three lines different, not be alike.

CELESTRY reads all eight characters and writes down which of them each area was read from.
