Timezone, Zi Hour, and Leap-Month Boundaries
This guide makes timezone, zi hour, and leap-month boundaries reproducible with explicit inputs, formulas, remainder mappings, worked checks, and boundary conditions.
OpenFate v2 uses Beijing civil time for the lunar date and the querent’s submitted local civil time for the hour branch. Zi begins locally at 23:00, does not advance the lunar day, and a leap month keeps its host month number.
This hybrid boundary is versioned product policy for global reproducibility, not the only historical school. Save the instant and both civil-time views so a later policy change cannot silently rewrite a stored cast.
Declare the casting method before calculating. Record the question, permitted inputs, represented instant and timezone when relevant, pre-modulo totals, remainder mapping, line order, and methodology version.
How does Timezone, Zi Hour, and Leap-Month Boundaries work?
Explain Timezone, Zi Hour, and Leap-Month Boundaries, reproduce its check, and identify the point where evidence ends.
How can you verify Timezone, Zi Hour, and Leap-Month Boundaries?
Reproduce Timezone, Zi Hour, and Leap-Month Boundaries from the recorded inputs, then label the result under the page's primary topic, “timezone, zi hour, and leap-month boundaries.” Preserve the first reading and disconfirming evidence before revising it.
What does Timezone, Zi Hour, and Leap-Month Boundaries include and exclude?
Use Timezone, Zi Hour, and Leap-Month Boundaries for this topic's definition, rule, reproducible check, source scope, and stopping condition. These pieces belong together because each limits how the answer should be read.
What are the limits of Timezone, Zi Hour, and Leap-Month Boundaries?
Use the result as a structured hypothesis. Keep observable evidence, uncertainty, and a reversible next action beside it.
What evidence supports Timezone, Zi Hour, and Leap-Month Boundaries?
Timezone, Zi Hour, and Leap-Month Boundaries cites 3 sources only for the claims each source can support. Primary transcriptions establish transmitted wording; scholarship and bibliography establish history; OpenFate code establishes current repository behavior only.
