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 Byeong (병, 丙) is the yang of Fire.
The branch Sul (술, 戌) is the yang of Earth.
Sul carries Mu (무, 戊), Sin (신, 辛), Jeong (정, 丁) inside it. Korean calls these 지장간 — the stems hidden in a branch.
The stem's element is the one that gives rise to the branch's.
On the calendar
Sul is the character for the month that opens at Hallo (Cold Dew), and for the hours from 7pm to 8:59pm.
It sits 23rd in the cycle of sixty. Days run in that order, so the same two characters come back every sixty days.
Days that were Byeong-sul 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.
