Rajab
Enable an AI agent to identify Rajab, resolve a particular year's occurrence under an explicit calendar authority, and support scheduling and observance decisions without assuming universal dates or practices.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to identify Rajab, resolve a particular year's occurrence under an explicit calendar authority, and support scheduling and observance decisions without assuming universal dates or practices.
It can be Resolve a mention of Rajab to the recurring month or a qualified annual occurrence.; Determine whether a timestamp falls within Rajab under a selected calendar context.; Convert a Rajab day to a Gregorian date while retaining the method and uncertainty.; Compare differing Rajab declarations without silently selecting one as universal.; Schedule or revise Rajab-related reminders using the user's chosen community and authority.; Present attributed observance information and identify questions requiring religious guidance..
Distinguishing features
The referent is the seventh Hijri month, between Jumada al-Thani and Sha'ban; this distinguishes it from Ramadan and similarly named non-temporal entities. [Egypt's Dar Al-Ifta](https://www.dar-alifta.org/en/article/details/1869/the-sacred-month-of-rajab)
Rajab belongs to the four sacred months; that classification does not identify every religiously significant month as Rajab. [Egypt's Dar Al-Ifta](https://www.dar-alifta.org/en/article/details/1869/the-sacred-month-of-rajab)
A dated occurrence requires a Hijri year and calendar context; the bare word Rajab identifies the recurring month rather than one unique interval.
An observance assigned to a day in Rajab is associated with the month but is not interchangeable with the whole month.
A Gregorian date range alone cannot establish a universally applicable Rajab occurrence without identifying the calendar method and relevant community.
Scope
+ Rajab's identity and position within the Hijri calendar
+ Year-specific occurrences qualified by calendar method, authority, and locality
+ Start, end, day numbering, and Gregorian correspondence
+ Evidence and confirmation state for month boundaries
+ Community-specific associations and their implications for scheduling
- The complete Hijri calendar and its calculation algorithms
- Astronomical models of lunar conjunction and crescent visibility
- Full models of Ramadan, Sha'ban, and other neighbouring months
- Ritual procedures and independent religious rulings
- Historical events and biographies associated with dates in Rajab
- People or places named Rajab
Characteristics
- Hijri month position
- Month 7 Provides the calendar identity used to distinguish Rajab from adjacent months.
- Occurrence year
- Integer Hijri year, with era notation Separates annual occurrences of the same named month.
- Calendar determination basis
- Observed crescent; calculated calendar; authority declaration; other documented method; unresolved Explains how a proposed or accepted Rajab interval was established.
- Applicable authority and community
- Named calendar provider or declaring body, locality, and adopting community Determines whose dates an agent should use for the requested action.
- Temporal boundaries
- Start and end dates or instants, with timezone and day-boundary convention Supports membership checks and prevents evening observances from being assigned to the wrong civil day.
- Boundary confirmation
- Predicted; declared; disputed; superseded; unresolved Controls whether a date can support a firm schedule or only a provisional plan.
- Position relative to a reference time
- Upcoming; current; elapsed; indeterminate Allows an agent to judge the occurrence's state using the selected boundaries.
- Observance association
- Linked observance, Rajab day or interval, community, attribution, and evidence status Supports relevant reminders while preserving differences in practice and interpretation.

Rajab calendar identity Recognise the named month and distinguish it from an occurrence or an associated event.
An agent must establish what Rajab denotes before attaching dates or religious significance.
Month recognition
Establish the intended temporal referent.
Seventh-month referent
Record whether the mention denotes the Hijri month and how the identification was established.
- Does Rajab here denote the Hijri month, rather than a person, place, or event title? definition
- Which language form and calendar context establish the intended month? provenance
Recurrence and neighbours
Locate a particular Rajab within its calendar year.
Qualified annual occurrence
Distinguish the recurring month from a year-specific interval between Jumada al-Thani and Sha'ban.
- Which Hijri year is intended, or is the statement about Rajab in every year? definition
- Which calendar context supplies the preceding Jumada al-Thani and following Sha'ban boundaries? boundary
Rajab boundary determination Represent how a community determines the beginning and completion of Rajab.
A predicted calendar date and an adopted declaration can support different levels of scheduling certainty.
Entry into Rajab
Capture the basis for identifying the first day.
Rajab start evidence
Associate the proposed or declared start with the method, issuing body, and adopting community.
- What observation, calculation, or declaration establishes 1 Rajab for this community? provenance
- Is that start predicted, adopted, disputed, or replaced by a later announcement? boundary
Transition to Sha'ban
Establish when the selected Rajab occurrence ends.
Rajab completion
Record the accepted final day and its relationship to the start of Sha'ban.
- What evidence establishes the transition from Rajab to Sha'ban under the selected method? boundary
- How many calendar days does this occurrence contain, and is that count provisional or settled? measurement
Rajab date resolution Make Rajab dates usable for timestamp interpretation and scheduling.
An agent needs explicit conversion and day-boundary conventions to act correctly on a Rajab date.
Civil date correspondence
Map a qualified Rajab date into another calendar.
Contextual date conversion
Preserve the conversion method and alternatives when resolving a Rajab day.
- Which Gregorian date corresponds to the requested Rajab day under the chosen year and calendar provider? measurement
- Do relevant authorities produce different dates, and which mapping applies to this task? boundary
Evening and day membership
Interpret nights, civil dates, and instants within the occurrence.
Rajab day interval
Resolve day membership using the applicable sunset or civil-date convention.
- Does the supplied Rajab date denote a sunset-based religious day or a civil calendar label? definition
- Which location, timezone, and boundary convention determine whether the requested instant belongs to that day? measurement
Rajab religious associations Separate sacred-month classification from attributed observances and practice claims.
Rajab's religious significance must remain usable without treating every associated custom as universal or obligatory.
Sacred-month significance
Record the classification and any attributed implications.
Attributed practice implications
Keep claims about conduct, fasting, and worship attached to their interpretive authority.
- Which source and interpretive authority support the claimed practical implication of Rajab's sacred-month status? provenance
- Does the requested action follow from an established user preference, or require a religious ruling beyond this model? action
Day-specific associations
Represent claimed Rajab anniversaries and observances as qualified links.
Commemoration date attribution
Distinguish a community's observance date from a claim about when a historical event occurred.
- Which community associates this observance with this day of Rajab, and what source documents that association? provenance
- Is the date an adopted commemoration, a historical dating claim, or both, and what remains disputed? definition
Rajab-aware planning Use qualified Rajab occurrences to plan and maintain relevant actions.
The model must connect calendar evidence to decisions, including changes after a declaration.
Planning readiness
Determine whether the available Rajab date supports the intended commitment.
Provisional or firm schedule
Match the scheduling decision to the user's authority choice and tolerance for date changes.
- Which Rajab authority or calendar does the intended audience follow? action
- Can this reminder or event use a predicted date, or must it await an adopted declaration? action
Declaration-driven revision
Maintain dependent plans when the adopted Rajab boundaries change.
Dependent date updates
Identify plans affected by a revised Rajab mapping and preserve the reason for the revision.
- Which reminders or events depend on the superseded Rajab start or day mapping? action
- What revised declaration justifies changing those dates, and which changes require user review? provenance
What the second pass must settle
- Does vr.tr.rajab encompass historical pre-Islamic uses of the month name, or only Rajab within Hijri calendars?
- Which calendar authorities, calculation methods, and locality rules must the deployed model support?
- Which Rajab observances should be linked for the intended communities, and which date or authenticity claims remain disputed?
- Which sources adequately distinguish broadly accepted sacred-month classification from differing rulings about Rajab-specific practices?
- How should conflicting or retrospective Rajab declarations affect previously completed actions and future schedules?
