Chinese Almanac · 老皇历
建除十二神
Every day in the Chinese almanac is governed by one of 12 archetypes — the Day Officers. They cycle continuously, shaping which activities are favored and which should be avoided. Understanding them is the key to understanding how traditional Chinese date selection actually works.
建 is the "founding" energy — the moment a seed is planted in ground. It aligns with the force of establishing, initiating, and laying structural foundations. As the officer that opens each lunar month, it carries authority and initiating power, but not universally favorable conditions for all events.
Traditionally used for: beginning major construction plans, planting crops, raising pillars, and starting large-scale projects. Less suited to personal celebrations or medical procedures.
除 means "to remove, sweep away, clear." It governs clearing and purification — the expulsion of stagnant or negative energy. While moderate for most events, it occupies a unique position: traditional almanacs specifically highlight it for medical treatment and cleansing rituals.
Traditionally used for: medical procedures, removing obstacles, clearing debts, reconciliation, and cleansing rituals. Often misunderstood as generally inauspicious — it is not.
满 means "full, abundant, overflowing." It carries the energy of completion and abundance — the cup filled to the brim. One of the most auspicious officers for celebrations and beginnings that involve receiving and accumulating.
Traditionally used for: weddings, moving into a new home, receiving guests, celebrations, starting businesses. Excellent for any occasion that benefits from an atmosphere of abundance.
平 means "flat, even, balanced." It is the officer of equilibrium and ordinary stable conditions. A 平 day is neither strongly auspicious nor inauspicious — it simply supports routine activities and everyday life without adding extra energy in either direction.
Traditionally used for: travel, signing ordinary documents, everyday business, social visits, and general tasks that don't require special energy.
定 means "settled, fixed, stable." It is the officer of committed, lasting energy — the kind that creates enduring foundations. 定 is especially prized for agreements and ceremonies where longevity and stability matter.
Traditionally used for: wedding ceremonies, signing important contracts, business openings, religious ceremonies, and major decisions intended to last.
执 means "to hold, carry out, execute." It is the officer of implementation and management — of doing the work that has already been decided. It supports steady, organized effort rather than new initiations.
Traditionally used for: collecting debts, managing affairs, organizing existing projects, and regular work tasks.
破 means "to break, shatter, destroy." It is generally the most inauspicious officer for new ventures and celebrations. But this reputation requires important nuance: the same "breaking" energy that destroys beginnings is exactly what is needed for demolition, clearing structures, and ending harmful cycles.
Traditionally avoided for: weddings, business openings, moving house, travel, and any new beginning. However, 破 days are traditionally acceptable — even suitable — for demolition work, breaking ground for construction, and ending things intentionally.
危 means "peril, danger, height." It is one of the two universally inauspicious officers — carrying unstable, precarious energy across essentially all activity types. Unlike 破, 危 lacks even a specific context where it shines.
Traditional guidance: avoid major events, travel, risky activities, and important decisions on 危 days. The one exception in some traditions: the character 危 also relates to "height" — some sources consider it neutral or even slightly positive for activities involving elevation or rooftops.
成 means "to succeed, achieve, accomplish." It is the crown jewel of the 12 Day Officers — the single most universally auspicious officer in the traditional almanac. 成 days carry the energy of fulfillment, achievement, and completion-through-excellence.
Traditionally suitable for: virtually any important event. Weddings, business openings, moving house, signing contracts, travel, ceremonies, medical procedures. When in doubt, a 成 day is the safest choice.
收 means "to receive, collect, gather." It carries the energy of gathering blessings, welcoming abundance, and receiving what has been earned. Particularly auspicious for celebrations that involve welcoming people, gifts, and new relationships.
Traditionally used for: weddings (receiving guests and blessings), financial transactions (collecting payments), harvest-related activities, business ceremonies, and any occasion centered on receiving.
开 means "to open." Along with 成 (Succeed), it is considered the most auspicious officer in the almanac. The character 开 literally means "open" — perfectly aligned with grand openings, new beginnings, and setting out on journeys. It carries expansive, forward-moving energy.
Traditionally used for: business grand openings (a 开 day for a "开业" opening is considered ideal — both use the character 开), new home move-ins, long-distance travel, wedding ceremonies, and starting major new life chapters.
闭 means "to close, shut." Its energy is contracting and terminal — the energy of endings, closures, and withdrawals. This makes it generally unfavorable for new ventures, openings, and celebrations. However, just as 破 has its niche in demolition, 闭 has a niche in intentional closure.
Traditionally avoided for: weddings, business openings, travel, and grand beginnings. Suitable for: completing tasks, closing accounts, ending relationships intentionally, and finishing renovation work.
