Hebrew calendar

Applicable Hebrew Calendar Regime

Record the intended regime and distinguish reconstruction of an attested date from retrospective application of fixed rules.

1. Does this use the standard fixed rabbinic calendar, an identified observational practice, or another specified Hebrew calendar tradition? definition
2. What evidence supports applying that regime to the community and period being represented? provenance

Traceable Calendar Rules

Associate leap-year, molad, postponement, and month-length rules with identifiable sources and implementation conventions.

1. Which source specifies the leap-year cycle, molad arithmetic, and postponement rules used here? provenance
2. When a calendar table and an implementation disagree, what evidence or designated authority determines which result the agent may use? action

Resolved Year and Cycle Position

Record the era, full year number, Tishrei transition, and cycle convention needed to determine intercalation.

1. What full year and era does the expression denote, particularly when thousands are omitted? definition
2. Under the selected fixed-calendar convention, what is the year's position in the 19-year cycle and is it common or leap? measurement

Valid Month and Day Combination

Distinguish Nisan-based numbering from Tishrei-based ordering, resolve Adar identity, and check dates against year-specific month lengths.

1. Which named month does the supplied label or number identify, and does an unqualified Adar require clarification in this year? definition
2. Do the calculated year length and Cheshvan and Kislev lengths permit this month-and-day combination? measurement

Resolved or Ambiguous Day Assignment

Record location and boundary conventions, including whether twilight leaves a date assignment unresolved for the intended use.

1. Which location, time zone, and solar-boundary calculation apply to this instant? measurement
2. Does the instant fall in a twilight interval or exceptional geographic situation for which the intended use requires a specified convention? boundary

Explicit Conversion Contract

Record the input's precision, the other calendar's identity, and whether the result denotes a conventional date correspondence or an interval of instants.

1. Is the input a Hebrew date label, a local civil date, or a timestamp, and is the other calendar Gregorian, Julian, or explicitly something else? definition
2. May the agent return one corresponding date, or must it return an interval or alternatives because time, location, or historical convention is missing? action

Authorized Hebrew Anniversary Policy

Record the purpose and governing policy for moving an anniversary between common and leap years or into a month lacking the original day.

1. For this recurrence's purpose, which Adar is used when moving between common and leap years, and who or what supplies that policy? provenance
2. If the original day does not exist in the target month, should the agent apply a specified adjustment, omit the occurrence, or leave it unresolved? action

Calendar-Derived Observance Schedule

Associate observance-date calculations with the applicable community, Israel or diaspora convention, and any sourced date-adjustment rule.

1. Which community and Israel or diaspora convention govern the requested observance schedule? definition
2. Is the requested result a nominal calendar date or an adjusted observance date, and which sourced rule permits any adjustment? boundary
