12 Day Officers
What Are the Twelve Day Officers (Jian Chu) in the Chinese Almanac?
Every date in the Chinese almanac is governed by one of the Twelve Day Officers—from Build (Jian) and Remove (Chu) to Success (Cheng) and Open (Kai)—setting the fundamental tone for what activities thrive that day.

The Twelve Day Officers cycle through Build, Remove, Full, Balance, Stable, Hold, Break, Danger, Success, Receive, Open, and Close. Match the officer to your goal: choose Success (Cheng), Open (Kai), or Stable (Ding) days for weddings, moves, and openings; choose Remove (Chu) days for decluttering or medical care; and avoid Break (Po) and Close (Bi) days for major celebrations.
How the Twelve Day Officers form the backbone of the almanac
Dating back over two millennia, the Twelve Day Officers (Jian Chu Shi Er Shen) rotate daily relative to the current solar-term month branch.
Rather than labeling a day simply 'good' or 'bad,' each officer describes a specific phase of qi—initiating, cleansing, filling, stabilizing, or closing.
The top four all-purpose officers: Success, Open, Stable, and Remove
**Success (Cheng)**: Completion and fulfillment—ideal for weddings, grand openings, signing contracts, and moving in.
**Open (Kai)**: Expansion and fresh momentum—great for business launches, housewarming, and starting new projects.
**Stable (Ding)**: Permanence and agreement—favored for engagements, marriage registration, and long-term contracts.
**Remove (Chu)**: Clearing out the old—best for deep cleaning, medical checkups, and ending outdated commitments.
Task-specific officers: Build, Full, Balance, Hold, Receive, and Danger
**Build (Jian)** suits travel and planning; **Full (Man)** suits celebrations and abundance; **Balance (Ping)** suits routine maintenance; **Receive (Shou)** suits collecting payments and saving; **Danger (Wei)**—despite its name—simply advises caution with high-risk physical activities while remaining fine for quiet domestic tasks.
Two officers to skip for major celebrations: Break (Po) and Close (Bi)
**Break (Po)** occurs when the day branch directly clashes the month branch (Month Breaker). Avoid it for weddings, moving, or openings—though it is traditionally used for demolition.
**Close (Bi)** represents inward storage and is unsuitable for launching new ventures or celebrations.

자주 묻는 질문
Success (Cheng), Open (Kai), Stable (Ding), and Full (Man) days are the classic favorites, paired with a clash-free zodiac check.
A Break Day happens when the day's Earthly Branch clashes with the month's Earthly Branch. It is avoided for joyful milestones but suits demolition or clearing.
