Purpose and description
Enable an AI agent to recognise a Rosh Hashanah observance, assess its timing and preparation, and support participation according to the relevant Jewish community's practices.
Rosh Hashanah is the Jewish New Year festival, beginning on 1 Tishrei and traditionally observed for two days, whose liturgy centres on divine kingship, judgment and remembrance and which opens the Ten Days of Repentance culminating in Yom Kippur.
It can be Identify and distinguish the recurring festival, an annual occurrence and its associated gatherings.; Build a location-specific schedule using a verified calendar and community practice.; Explain ritual and household practices with their community attribution and degree of obligation.; Prepare service and meal arrangements that reflect participants' stated needs.; Identify unresolved religious-practice questions and route them to an appropriate human authority.; Record what occurred without inferring participants' beliefs or religious standing..
Distinguishing features
The occurrence is identified with the Jewish New Year associated with Tishrei, rather than merely with any beginning of a calendar year.
Rosh Hashanah-specific liturgy or shofar practice can support identification, but an individual's nonparticipation does not make the festival occurrence cease to be Rosh Hashanah.
Its relationship to Yom Kippur must preserve two distinct observances rather than treating the names as interchangeable.
Symbolic foods and greetings support identification only in context; apples and honey alone do not establish that an event is a Rosh Hashanah observance.
The model distinguishes the recurring festival from a particular service, meal or annual occurrence associated with it.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Festival identity and meaning Establishes which observance is meant and how its religious significance is represented.
The absent registry definition leaves both the referent level and the treatment of religious meanings to be established explicitly.
Name and referent
Separates Rosh Hashanah itself from gatherings and related observances.
Identify the observance
Record whether the subject is the recurring festival, a dated occurrence or an associated activity.
- Does this record describe Rosh Hashanah generally, a particular Hebrew-year occurrence, or a service or meal held for it? definition
- What evidence distinguishes this referent from another Jewish new-year observance or a generic New Year event? boundary
Attributed religious meanings
Represents interpretations without assigning identical beliefs to every participant.
Renewal, judgment and remembrance
Attribute explanations of the festival's themes to texts, teachers or communities rather than presenting theological claims as empirical states.
- How does the identified community explain the relationship between the new year, judgment, remembrance and renewal? definition
- Which consulted text or community explanation supports each interpretation included here? provenance
Calendar and observance boundaries Locates an occurrence in the Hebrew calendar and translates it into a usable local schedule.
An incorrect day, duration or evening boundary can make otherwise appropriate participation guidance unusable.
Annual occurrence
Identifies the year, dates and community-specific duration.
Resolve year and duration
Use an identified calendar and community practice to establish which days are observed.
- Which Hebrew year and corresponding civil dates identify this Rosh Hashanah occurrence? measurement
- Does the relevant community observe one or two days, and what source establishes that practice? provenance
Local times and adjacent days
Handles local start and end boundaries and their interaction with Shabbat.
Establish local boundaries
Separate civil-date labels, religious observance boundaries and published service times.
- What location, time zone and calendar authority determine the festival's local beginning and ending? measurement
- Does an overlap or adjacency with Shabbat change preparations or the timing of particular practices under the community's guidance? action
Shofar and festival worship Represents the planned and actual provision of Rosh Hashanah worship and shofar observance.
Service content and shofar arrangements require distinct decisions that cannot be inferred from the festival date alone.
Shofar practice
Captures the applicable practice, its provision and reasons for variation or omission.
Determine shofar arrangements
Establish when and how shofar sounding is provided, including any relevant calendar or participation constraints.
- What shofar sounding is planned, at which times, and according to whose practice? action
- What circumstances change or suspend the planned sounding, including a festival day falling on Shabbat? boundary
Festival liturgy
Identifies the actual prayer rite, prayer book and service arrangements.
Identify service form
Treat liturgy as a named community practice rather than assuming one universal service order.
- Which prayer rite and machzor edition govern the service, and how are Rosh Hashanah-specific elements identified? provenance
- What service times, language support, admission arrangements and accessibility provisions must a participant know? action
Household and social observance Covers festival meals, symbolic foods and interpersonal expressions of the new year.
Household observance is substantial in its own right and varies across families and Jewish communities.
Festival meals and symbolic foods
Connects meal choices to their stated custom, meaning and participants' needs.
Attribute food customs
Record symbolic foods and associated words or actions without making a familiar regional custom mandatory for everyone.
- Which symbolic foods and accompanying blessings or wishes does this household use, and from which tradition? provenance
- How should the meal accommodate dietary practice, allergies and available substitutions while respecting the host's stated custom? action
Greetings and hospitality
Supports appropriate social participation around the festival.
Coordinate respectful participation
Make invitations, greetings and guest expectations explicit without inferring religious commitment.
- Which new-year greetings and languages are appropriate to the participants and setting? action
- What should guests know about meal timing, expected participation and household festival practices? action
Preparation and penitential context Connects practical readiness and reflective practices to Rosh Hashanah while preserving the boundaries of neighbouring observances.
An agent needs to support preparations and related practices without treating the entire High Holy Day period as one event.
Festival readiness
Identifies advance arrangements affected by the participants' observance practices.
Prepare under stated practice
Base preparation decisions on explicit guidance about festival activity and participants' practical needs.
- What work, travel, cooking or device-use practices affect this participant's Rosh Hashanah plans? boundary
- Which arrangements must be completed before the local festival boundary, and which remain unresolved? action
Reflection and related observances
Records links to repentance, Tashlich and Yom Kippur without requiring identical participation.
Locate associated practices
Identify which reflective or customary activities belong to this occurrence and which belong to the surrounding period.
- Does the community practise Tashlich, and what source establishes its timing, form or postponement for this occurrence? provenance
- How are Rosh Hashanah's penitential themes related to Yom Kippur while keeping the two observances distinct? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

What the second pass must settle
- Does an existing Vercy world model already own Rosh Hashanah or provide an authoritative parent model to which this registry entry should link?
- Which Jewish communities and household traditions must the initial researched model represent, and which sources adequately establish their differences?
- Which calendrical authority and exceptional-location rules should govern local observance boundaries when ordinary sunset-based schedules are insufficient?
- Which proposed practices are requirements, customs or optional activities under each represented authority, particularly for shofar, Tashlich and festival activity?
- How should the model represent cultural or secular participation without presuming assent to theological interpretations or full ritual observance?
