Introducing Best Dates Guide To The 12 Day Officers

When planning something important — like starting a project, getting married, or launching a business — choosing the best dates makes all the difference. If you want to understand how to steer clear of the bad days, check out our earlier post here. After removing the inauspicious ones, you’ll notice something — there aren’t that many “good” days left in the year! But let’s be clear: not all leftover dates are truly “good.” We call them usable dates — meaning they are not harmful, but they aren’t necessarily the best either.

Your personal best dates contain energies of the day that support your activity. Therefore, it includes:

• The stars on that day are positive. For example, the 12-Day Officers
• The day’s elements blend well with the month and year.
• Ideally, a match to your personal BaZi birth chart (without clashing with your year pillar).

Some dates may appear appealing on the surface, but they contain negative stars that limit their benefits. Although they are safe to use, they provide little benefit. Therefore, not every usable date is genuinely useful. In traditional Chinese metaphysics, classics such as The Book of Unifying Times and Discerning Dimensions (协纪辨方书) are used to calculate these dates. Thus, these methods help ensure these dates truly support your goals.

With just a bit more knowledge, you can find the best dates using the 12-Day Officers to match your goals — whether it’s starting a new job, launching a project, or even getting married.

The Ancient Book Behind Understanding the Best Dates

During the Qing Dynasty, Emperor Qianlong (乾隆) brought together top astronomers from China and Europe. Together, they merged ancient Chinese star knowledge with Western astronomy to create one of the most accurate calendar systems in history. Therefore, they called it 《协纪辨方书》, or The Book of Unifying Time and Discerning Dimensions. This work is the foundation for most timing systems in Chinese metaphysics.

This ancient text explains how time, stars, and energy flow throughout the year. It clearly states which days carry what type of energy, how the stars and constellations affect outcomes, and even includes hexagram references for choosing dates. Even farmers back then relied on this knowledge to decide the best days to plant and harvest. As a result, if they got married on a particular date, the book could even predict how many children they might have or how long they might live!

Today, we know this system as the Tong Shu (通书). You can find many versions — from detailed professional editions to simple cartoon-style guides. Even if you don’t fully understand all the traditional terms, you can still use the Tong Shu to find the best and worst days for everyday activities. Thus, the easiest approach to the Tong Shu is to use the 12-Day Offices.

What is the 12-Day Officers Method in Date Selection?

The 12 Day Officers Method (建除十二值神) is one of the easiest ways to start learning Chinese Date Selection. It helps you sort out which are the best dates from the rest of the usable dates. This method is also known as the “12 Day Deities” — but don’t worry, these aren’t actual gods. In this case, the word “Deity” means a type of energy or “Qi” in charge of that day.

Each day of the month contains one of these 12 “officers.” Thus, these energies tell us what kind of activities are suitable or not suitable for that day. Think of each officer as someone giving the day its mood or purpose — for example, some days are good for starting things, others are better for rest or letting go.

Therefore, here is a brief explanation of the 12-Day officers:

• Establish (建) – Start something strong. Great for beginnings.
• Remove (除) – Eliminate what doesn’t serve you.
• Full (满) – A day of abundance. Things feel complete.
• Balance (平) – Balance or maintain fairness
• Stable (定) – Calm things down. Ideal for steady progress.
• Initiate (执) – Take action. Get things moving!
• Destruction (破) – Break old patterns. End things decisively.
• Danger (危) – Use carefully. Brings risk, but also opportunity.
• Success (成) – Go big. Launch, marry, move. Win.
• Receive (收) – Collect rewards, money, or results.
• Open (开) – Open new paths and invite opportunity.
• Close (闭) – Rest, reflect, and focus inward.

This method helps you schedule tasks for days that align with your goals. It’s easy, it works, and it’s a great way to select the best dates.

Establish (建) Day – Starting Anew, Start Afresh!

The Establish (建) Day is great for starting new things, but not everything. In ancient times, these were the best dates emperors would pray for good harvests. Thus, it marked the beginning of a hopeful season.

✅ However, nowadays you can use an Establish (建) Day to:

• 💼Start a new job or take on a new role
• 👩🏻‍💼Begin business talks or negotiations
• 👰Get engaged or propose (but not for the wedding itself)
• 🤝Meet someone to discuss plans or deals
• 🏫Start a course, school, or a long journey
• 🛠️Begin construction (but not for groundbreaking or demolition)
• 🩺Seek medical help or start treatment

In ancient times, “visiting friends” could refer to traveling to discuss serious matters, such as marriage or commerce. But in today’s world, this entails attending business meetings, networking, and initiating interactions that may lead to future collaboration.

❌ Avoid using the Establish (建) Day for :

• Funerals, burials
• Any activity that involves breaking or tearing down (like demolition or groundbreaking ceremonies)

---

Remove (除) Day – Letting Go, Clearing Out

A Remove (除) Day is great for clearing, cleansing, or removing unwanted energy or items. It’s not suitable for starting something new, especially not important life events. Therefore, you can use Remove (除) Days to cut ties, eliminate problems, or cleanse your space — but not for beginnings or celebrations.

✅ Remove (除) Days are good for:

• Cleansing your home or space (physical or spiritual)
• Letting go of toxic relationships
• Starting a diet or detox (removing fat or toxins)
• Medical procedures to remove something (e.g., surgery, tooth extraction)
• Demolition work or major repairs
• Clearing old inventory or unwanted stock from your business

❌ However, you should avoid using Remove (除) Days for:

• Traveling can cause problems with immigration or returning home
• Weddings or proposals (linked to separation or short marriages)
• Adopting pets (traditionally seen as unlucky — pets may fall ill or go missing)
• Moving into a new home (can symbolize eviction or instability)
• Opening a new business (implies you may shut it down soon)
• Starting a new job or role at work

---

Full (满) Day – Great for Big Results and Positive Multiplication

A Full (满) Day is perfect when you want to gain more of something — more success, more results, more returns. In ancient times, it could help you attract abundance and prosperity. Today, it’s best for activities where you want big and bountiful outcomes.

✅You can use a Full (满) Day to:

• Sign business contracts (especially for expansion or launching multiple outlets)
• Open a new business or store (including franchises or chain stores)
• Collect debts (you’re more likely to collect the full amount)
• Hold a housewarming or install new equipment in your home or office

But use caution if the agreement you’re signing is “full” of duties or legal responsibilities, a Full (满) Day might also bring more of that. As a result, you should avoid using it to sign legal settlements or file lawsuits, as it may lead to additional legal problems. Also, if you’re taking on a new job, think twice: you might end up with a “full plate” of work and stress!

In traditional times, Full (满) Days were considered great for marriage (more wives = more wealth). But today, that doesn’t apply. So it’s better not to choose a Full (满) Day for weddings, unless you’re ready for extra drama down the line.

❌ Avoid using Full (满) Days for:

• Demolition or destruction
• Burials
• Starting a job with a heavy workload
• Legal or settlement matters
• Marriage

Use a Full (满) Day only when you want to multiply good things, not stress or problems.

---

Balance (平) Day – Best for Fair Outcomes and Mutual Benefits

A Balance (平) Day is ideal when you’re looking for fairness, harmony, and mutual gain.

✅ The Balance (平) Day is great for activities like:

• Marriage
• Business talks
• Starting communications
• Travelling
• Beginning construction.

These are days that create win-win results — both sides benefit equally. Some people might consider Balance (平) Days “neutral” rather than “lucky,” because they don’t tilt the outcome in your favor. But here’s the trick: if you’re in a weaker or less powerful position, a Balance (平) Day can level the playing field. It is a great day to use when you’re David going up against Goliath — it helps bring fairness to the situation.

❌ However, Balance (平) Days aren’t good for:

• Starting lawsuits — outcomes tend to drag on and settle fairly, not in your favor
• Dividing assets or contesting wills — you likely won’t get more than your share
• Burials or funeral activities — the energy isn’t suitable for closure or endings

So if you’re looking to negotiate, collaborate, or start something that benefits everyone involved, a Balance (平) Day supports smooth and fair beginnings.

---

Stable (定) Day – For Long-Term Plans That Last

A Stable (定) Day is perfect when you want something to last a long time. Use it for things you want to keep going “forever” — like marriage, starting a business, or making a big life commitment. As a result, it’s a wonderful day for finalising long-term projects, opening a shop, hiring key staff, or even getting medical treatment where you want a lasting cure.

✅ You can also use Stable (定) Days for:

• Buying a pet (for long-term companionship)
• Having a housewarming (if you want lasting happiness in the home)
• Signing long contracts or agreements

❌ However, don’t use a Stable (定) Day to:

• Move into a new house (it may suggest you’ll keep moving!)
• Hold a funeral or burial (not suitable energy)
• Travel (you might get stuck or delayed)

If you’re starting a new job or project, only use a Stable (定) Day if you’re ready to commit to it for a long time. For a short-term gig or temporary role, it’s better to choose another day. Stable (定) Days bring long-term energy, so only use them when you’re in it for the long haul.

---

Initiate (执) Day – A Fresh Start for New Beginnings

An Initiate (执) Day is great for starting something new. Therefore, if you’re beginning a new project, signing an agreement, or starting renovations, this is the day to do it. It’s also suitable for launching your business, accepting a new job, or taking on a new role — anything where a solid foundation is crucial.

✅ That’s why people often choose Initiate (执) Days when:

• Launching a new product
• Kicking off business plans
• Beginning construction or groundbreaking

However, Initiate (执) Days are not the strongest days in the Chinese calendar. They’re considered “usable” but not necessarily powerful. In classical writings, we can choose Initiate Days only if there is no other option or if the day has favorable stars to enhance it.

❌ Avoid using Initiate (执) Days for:

• Traveling (possible disruptions or problems on the road)
• Moving into a new home (it may not bring lasting harmony)

---

Destruction (破) Day – Best for Breaking, Not Building

As the name suggests, Destruction (破) Days are best for doing things that involve tearing down or breaking away.

✅Therefore, it’s a good day to use for:

• Demolishing buildings or removing physical structures.
• Break something down, clear the land
• Ending a relationship
• Quitting a bad habit

Some ancient books suggest that it’s also acceptable for medical procedures that involve removing something from the body. But if possible, it’s better to choose a gentler day for health-related matters.

❌ Avoid using Destruction (破) Days for positive or significant events, like:

• Weddings or engagements
• Starting a business
• Going on a trip
• Signing important contracts

These events bring growth and joy, so you wouldn’t want to start them on a day filled with “breaking” energy.

---

Danger (危) Day – Handle with Care

Danger (危) Days carries a mix of uncertainty and risk. Thus, as the name suggests, these days are not stable and can bring unpredictable results. That said, traditional Chinese Date Selection texts also note that some positive stars can still appear on these days, making them usable, but only for specific activities.

✅You can use a Danger (危) Day for:

• Religious prayers or rituals
• Groundbreaking ceremonies
• Adjusting bed positions
• Taking things apart or dismantling objects

However, these days come with a risk element. So it’s best to avoid any high-risk activities, such as:

• Adventure sports
• Being on rooftops or high places
• Sea travel or water-related journeys
• Starting long-distance trips

❌ Therefore, it’s not suitable for important life events like weddings or funerals, where safety, stability, and peace are needed.

---

Success (成) Day – The Best Dates to Start Something Important

Among the 12 types of “Day Officers,” Success (成) Day is the most positive. It carries strong, supportive energy that brings good results. That’s why it’s perfect for starting any significant activity where you want a positive outcome.

✅ Success (成) Days are great for:

• Getting married or proposing
• Submitting a business proposal
• Starting construction
• Moving into a new house
• Seeking medical treatment
• Even conducting a burial (more on this below)

Why burial? In Chinese metaphysics, a good burial day symbolizes that the grave is in a strong Feng Shui spot. When this spot is activated correctly, it brings blessings to the deceased’s descendants—health, wealth, and harmony for future generations.

❌But beware! Since Success (成) Days multiply the outcome of any event, you should never use them for negative things like filing lawsuits. The energy may make the legal issue worse or take longer than anticipated.

---

Receive (收) Day – A Day to Gain, Ask, and Get

A Receive (收) Day is perfect when you aim to obtain something, such as a reward, offer, or positive outcome.

✅Therefore, you can use the Receive (收) Day when you want to:

• Start school or join a course
• Collecting money from debtors
• Sign a job contract or begin a new job
• Close a business deal or ask for a raise
• Propose marriage or propose any partnership

Traditional Chinese metaphysics confirms these are the right types of actions for Receive (收) Days — they support giving and receiving energy in your favor.

❌However, you should steer clear of Receive (收) Days for:

• Funerals or burials (you don’t want to “receive” sorrow)
• Doctor visits or medical treatments (avoid taking on illness)
• Visiting sick people (you could “receive” their illnesses unintentionally)

Think of it as a day that aligns with success in giving and acquiring, not for letting negativity in.

---

Open (开) Day – Perfect for Welcoming and Starting Up

An Open (开) Day is all about opening doors—literally and symbolically. Open (开) Days are stronger than Initiate Days—they’re for people who’ve already started something and want to build and invite more energy into the venture.

✅Therefore, it’s ideal for:

• Starting a new job or school/course
• Signing deals, agreements, or contracts
• Housewarmings or welcoming new guests
• Getting married or hosting engagement ceremonies
• Official openings like shop launches or office debuts
• Resuming work after a break (e.g., post-holiday return)

Use it whenever you’re starting something fresh and inviting energy in (e.g., a new role, project, relationship).

❌However, you should avoid Open (开) Days for these activities:

• Burials or funerals (Death isn’t aligned with energy)
• Groundbreaking or excavation (not for demolition or digging)
• Any scenario that makes you vulnerable, such as legal problems, surgeries, or conflicts.

Choose an Open (开) Day when you’re looking to welcome, launch, or reunite with others. It lights the way forward—but steer clear of it for digging, closing things down, or when you’re vulnerable to risk.

---

Close (闭) Day – A Time to Pause, Not Proceed

A Close (闭) Day marks the end of the 12-day cycle in Date Selection. Thus, on this day, the Qi (energy) is minimal and stagnant—think of it as a low-energy day where nothing really starts or moves forward. Therefore, you can think of it as your annual reset or cooldown day. Take time to recharge your mind and space. Then, come back stronger on the next Establish Day.

✅What You Can Do on a Close (闭) Day:

• Rest, reflect, or meditate
• Do light tasks or housekeeping
• Organize finances or finish old chores
• Healthy to wrap up small projects, pay bills, or close accounts

❌Don’t begin anything crucial. It’s not a good day for:

• Big business deals
• Moving into a new home
• Signing important contracts
• Launching new ventures or trips
• Seeking serious medical treatment
• Getting married or renewing vows

There’s No Perfect Day — Only the Right Use

Each of the 12 Day Officers represents a specific type of energy, also called a “governing body of Qi.” Every day has a unique officer, and each officer supports certain activities. So, how do you use this for Date Selection? You should match the type of Qi (the Day Officer of the Day) to the activity you plan to do.

Therefore, it’s a misunderstanding to think that a day is either completely lucky or unlucky. Most days carry both positive and negative energies. Thus, it all depends on how you choose to use it. Every day has a purpose — your job is to match the right day to the right action. However, the only exceptions are the Success Day (very positive) and the Destruction Day (mostly negative), which are more one-sided in their energy.

Last but not least, unlock the secrets of the best dates, good timing, and plan smarter.
