Saju & BaZi Four Pillars date selection — real estate, leases, business agreements
A Saju date selection reading identifies the best contract-signing day by first eliminating dates that clash your Day Branch, carry the Three Killings (San Sha), or fall on a Sui Po year-breaker day. From the remaining candidates, the practitioner ranks days by how well their Heavenly Stem and Earthly Branch energy reinforces your useful god element and the specific nature of the agreement.
In both Korean Saju and Chinese BaZi practice, the moment a binding agreement is executed carries its own stem-branch energy — a Four Pillars snapshot of that instant. Because legal agreements create durable obligations, the energetic quality of the signing moment is treated as the foundation of the contractual relationship itself. A day whose Earthly Branch clashes with one party's Day Pillar places immediate structural stress on that party's position within the agreement. A day that harmonises with both parties' charts gives the agreement a stable energetic base.
This is not a guarantee that a good day produces a good deal. It is the more precise claim that avoidable timing hazards should be avoided when they are within your control — particularly when the financial stakes are high.
The following day-types are removed before any personal chart analysis takes place. They are documented in classical Four Pillars and Tong Shu almanac traditions and apply regardless of the individual's birth data:
| Hazard | What It Is | Why Practitioners Avoid It |
|---|---|---|
| Day Branch Clash | The day's Earthly Branch directly opposes your Day Branch. The twelve clash pairs are: Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog, Snake–Pig. | Direct clash disrupts your personal qi and places you in a structurally disadvantaged position relative to the agreement from the moment of signing. |
| Sui Po (Year Breaker) | The branch that directly clashes the current year branch. In 2026 (Year of the Horse, Wu 午), Sui Po days are Rat-branch (Zi 子) days. | Year-breaker days are considered universally destabilising for new commitments. Classical texts consistently exclude them for any action intended to create lasting obligations. |
| Three Killings (San Sha) | Three branches opposed to the year's seasonal elemental group. In a Fire-group year such as 2026 (Horse), the Three Killings fall on Pig (Hai 亥), Rat (Zi 子), and Ox (Chou 丑) branch days. | Initiating binding obligations on San Sha days is classically associated with litigation, unexpected financial loss, and contractual disputes. |
| Destroy Day (Po 破) | The seventh of the 12 Day Officers in the monthly cycle. | The Po officer carries the energy of rupture and dissolution — the direct opposite of what a durable agreement requires. |
| Danger Day (Wei 危) | The eighth of the 12 Day Officers. | Associated with instability and unforeseen hazard. Avoided for legally binding acts across classical and modern Tong Shu practice. |
| Fu Yin | The day's stem-branch is identical to one of your natal pillars. | Creates a stagnant, inward-drawing energy that suppresses forward momentum — problematic for initiating new agreements. |
| Fan Yin | The day's stem-branch clashes with all four of your natal pillars simultaneously. | Total clash across the chart creates acute instability. One of the most serious conditions a practitioner will eliminate first. |
Once hazard days are removed, the practitioner evaluates candidates for positive alignment across four criteria:
The secondary weighting of elemental energies shifts depending on what is being signed:
| Contract Type | Preferred Day Energy | Primary Risk to Manage |
|---|---|---|
| Real estate purchase | Earth and Metal (stability, asset solidification) | Clash with your Year Branch — property is tied to long-horizon asset accumulation |
| Business partnership deed | Wood (growth) or your personal useful god element | Fu Yin — stagnation undermines a relationship built on forward momentum |
| Commercial or residential lease | Stable (Ding 定) officer days; Earth Heavenly Stems | Sui Po and San Sha — lease disputes are disproportionately common when these are ignored |
| Loan or finance agreement | Metal or Water (financial flow and circulation) | Fan Yin — total chart clash energetically destabilises repayment capacity |
| Employment contract | Day harmonising your Month Branch (the career pillar) | Day clashing the Month Branch directly undermines career stability from the start date |
In an ideal consultation, both signatories provide their full birth data and the practitioner identifies a day with no harmful interactions for either party. When both charts are available it is also possible to find days that actively benefit both — a genuinely cooperative starting point that generic almanac applications cannot provide.
If only your chart is available, the reading focuses on protecting your pillar and flagging any dates that create an asymmetric disadvantage for you relative to the other party.
Yes. A personalised date selection reading cross-references the stem-branch composition of each candidate day against your Four Pillars chart. Days that clash your Day Branch, form Fu Yin or Fan Yin with your chart, or carry universal hazards such as Sui Po or the Three Killings are eliminated first. From what remains, the practitioner identifies days whose Heavenly Stem and Earthly Branch energy reinforces your useful god element and the nature of the transaction. Generic almanac apps skip the personal chart layer entirely.
Regardless of personal chart, practitioners universally avoid: (1) days whose Earthly Branch directly clashes your Day Branch; (2) Sui Po year-breaker days — in 2026, the Horse year, these are all Rat (Zi 子) branch days; (3) Three Killings days — in 2026 those are Pig, Rat, and Ox branch days; (4) the Destroy (Po 破, 7th officer) and Danger (Wei 危, 8th officer) days in each month's 12 Day Officer cycle; and (5) days forming Fu Yin or Fan Yin with your natal chart. These are elimination criteria, not a complete analysis.
The method is routinely applied to real estate purchase agreements, commercial and residential leases, business partnership deeds, employment offer acceptances, loan and finance agreements, and trademark or IP assignments. The Stage 1 elimination criteria are identical across all types. The Stage 2 ranking criteria shift — for instance, Earth and Metal day energy is weighted more heavily for property transactions, while Wood or useful-god-matching days are prioritised for partnership deeds.
Ideally yes. When both charts are available, the practitioner finds a day that avoids direct clashes for each party and ideally benefits both. If only your chart is available, the reading focuses on protecting your pillar and flagging any dates that could create an asymmetric disadvantage for you relative to the other party. A day that looks strong for you on the surface may place your counterparty in a Fu Yin condition, which can manifest as post-signing resentment or disputes.
When constrained, the practitioner ranks available dates from least harmful to most favourable and presents the best option within your window alongside an honest explanation of its limitations. If every date carries some risk, guidance shifts to mitigation: which hour of the least-bad day is strongest for your chart. A practitioner-level reading will never label a genuinely poor day as auspicious simply to provide a confident-sounding answer.
A generic Tong Shu app lists dates as universally auspicious or inauspicious based only on the 12 Day Officers, Yellow-Black Road stars, and annual hazards — with no reference to your personal chart. A personalised Saju reading layers your unique Day Branch, useful god element, and current 10-year luck cycle on top of those universal markers. The same date that an almanac labels auspicious for everyone may be a direct clash day for your specific chart.
At least two to four weeks before your target signing date. This allows time to evaluate multiple candidate days across a realistic window, cross-check both parties' availability against the auspicious options, and avoid the pressure of accepting a poor date simply because the calendar is constrained to two or three days. Last-minute requests often result in the practitioner being forced to rank bad options rather than identify genuinely good ones.
