How Monthly Influences Work
Use solar-term month boundaries to refine an annual hypothesis, preserve the natal Month Pillar, and avoid month-by-month guarantees.
Overview
Monthly influences are dated stem-branch layers bounded by solar terms, not Gregorian or lunar calendar months. They refine an annual and Luck-Pillar context; they do not replace the natal Month Pillar. Calculate the month stem from the annual stem under the published rule, retain the exact solar-term timestamps and timezone, then inspect named contacts to the natal chart. A monthly contact narrows a hypothesis but cannot guarantee a monthly event.

Build the monthly interval from solar terms
Use the exact solar-term instant in the selected IANA timezone to determine when each Bazi month begins and ends.
Do not substitute the first day of a Gregorian or lunar month.
- Store both boundary timestamps.
- Publish timezone and ephemeris policy.
Calculate the complete monthly pillar
Assign the solar-month branch and derive the month stem from the annual stem with the registered Five-Tigers sequence.
Keep the resulting pillar in a timed layer rather than overwriting the birth Month Pillar.
- Verify stem and branch together.
- Preserve natal and timed provenance.
Use the month to refine an existing hypothesis
Compare the monthly Jiazi with the natal chart, active Luck Pillar, and annual Jiazi for named Ten-God and stem-branch pathways.
Increase specificity only when it reinforces an already supported mechanism; keep competing relations and counterevidence.
- Start from longer-cycle evidence.
- Avoid searching every month for a story.
A monthly contact is not a monthly promise
It cannot guarantee transactions, meetings, conception, recovery, conflict, travel, or any other event.
Use current schedules, records, consent, and professional advice for real decisions.
- Avoid calendar determinism.
- Do not time high-stakes action from Bazi alone.
