BaZi
Four Pillars are four stem-branch pairs: year, month, day, and hour.
Heavenly Stems and Earthly Branches
Stems and Branches are the shared time language behind BaZi, Huang Li, Chinese zodiac, solar-term months, and Chinese hours. If you can read one stem-branch pair, the rest of MingSez becomes easier to understand.

Example: Jia Zi / 甲子
Jia / 甲
Yang Wood: direct growth, first movement, upright planning
Zi / 子 Rat
Water, north, winter depth, 23:00-01:00 hour
Read it in two steps: the stem gives the visible quality, and the branch gives the rooted timing context. A BaZi or Huang Li reading then asks how that pair meets the other pairs around it.
How the 60 cycle works
Ten stems and twelve branches rotate together.
The cycle starts at Jia Zi / 甲子, then moves one stem and one branch at a time. The stems repeat every 10 steps and the branches repeat every 12 steps, so the same starting pair only returns when both cycles meet again at 60.
Step 1
Jia Zi / 甲子
Yang Wood over Rat
Step 2
Yi Chou / 乙丑
Yin Wood over Ox
Step 3
Bing Yin / 丙寅
Yang Fire over Tiger
Step 31
Jia Wu / 甲午
The stem cycle has restarted, but the branch is now Horse
Step 60
Gui Hai / 癸亥
Yin Water over Pig
Why not 120?
Only matching stem-branch parity is used: Yang stems pair with Yang branches, Yin stems with Yin branches.
Middle of the cycle
By step 31, Jia returns, but it pairs with Wu / Horse instead of Zi / Rat.
Full return
By step 60, both rotations have completed their shared round and the next step opens Jia Zi again.
The same code appears across the tools.
Daily Ming
The day pillar helps explain today's timing cue.
Chinese Almanac
The selected date can show day and year pillars alongside Yi/Ji guidance.
BaZi
Your Four Pillars are four stem-branch pairs: year, month, day, and hour.
Chinese hours
Each two-hour period is an Earthly Branch moving through the day.
What are Heavenly Stems?
The Heavenly Stems are ten symbolic qualities linked with Yin and Yang forms of the Five Elements. They give time an elemental tone: growing Wood, visible Fire, steady Earth, refined Metal, and flowing Water.
What are Earthly Branches?
The Earthly Branches are twelve time rhythms most people recognize through the Chinese zodiac animals. Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig are the outer doorway into a deeper timing pattern.
How they connect to zodiac
Each zodiac animal is connected with an Earthly Branch. That is why the zodiac is more than personality. It is a way of naming a branch of time, with its own season, direction, and elemental relationship.
How they connect to Five Elements
Stems and Branches both carry elemental meaning. A reading looks at how these elements support, challenge, or balance one another. MingSez begins with the clearest visible layer so the pattern can be understood before adding more detail.
Why they matter for BaZi
BaZi, or the Four Pillars, uses the Stem and Branch of the year, month, day, and hour. Those eight characters become a symbolic map of timing, tendency, and movement.
How MingSez keeps it simple
MingSez starts with what a reader can actually use: the date, the day pillar, the zodiac branch, the visible element pattern, and one practical next step. The goal is to make the language readable before making it technical.
