What it is Filled
Passover (Hebrew: Pesach) is the Jewish festival that begins at nightfall on 15 Nisan and commemorates the Exodus from Egypt through a household ritual meal (the seder, with Haggadah recitation), a week-long ban on chametz (leaven from the five cereal grains), and the eating of matzah; in biblical law the name denotes the 14 Nisan paschal offering, later fused with the seven-day Festival of Unleavened Bread.
In scope
- Identification of an occurrence as Passover and its relationship to the annual festival
- Locally applicable festival dates, day boundaries and phases
- Seder arrangements, narrative participation and ritual readiness
- Passover-specific food standards and handling of chametz
- Participants' adopted customs, observance commitments and unresolved decisions
Out of scope
- Historical reconstruction of the Exodus and adjudication of its historicity
- Judaism as a religion or a complete model of Jewish law
- General household inventory, catering operations and food-safety management
- Synagogue administration and year-round worship scheduling
- Independent Christian commemorations or other events using Passover terminology
- General travel, employment and school-calendar management
Why it exists Filled
Enable an AI agent to recognise a Passover observance, assess its preparation and current state against the participants' declared practice, and identify appropriate next actions.
Distinguishing features Filled
- The occurrence is explicitly identified as Jewish Passover or Pesach; a shared date or the word Passover alone is insufficient.
- The observance connects its identity to remembrance and transmission of the Exodus, rather than merely being a seasonal communal meal.
- The model distinguishes the festival from an individual seder: a seder may belong to a Passover occurrence without exhausting its scope.
- Matzah, chametz-related commitments and seder practices are recorded as Passover-specific dimensions, while omissions or adaptations do not automatically invalidate identification.
- Dates and practice are established from the participants' location, community and adopted authority rather than inferred solely from a generic holiday calendar.
What robots and AI may and may not do Filled
Must not
- Mislabel food as kosher for Passover when it is not certified or checked.
- Repeat antisemitic myths connected with the festival, such as blood libel, except to explain and refute them.
- Present one community's customs as binding on all Jews.
- Schedule required work or exams for observant people on the holy days without accommodation.
Only with a human decision
- Certifying food or a kitchen as fit for Passover use.
May
- Give the festival's dates and customs, noting differences between communities.
- Help plan a seder, including food that meets a household's chosen dietary rules.
Moral aspects Filled
- Passover has been a pretext for antisemitic violence in history.
- Religious observance deserves accommodation at work and school.
Who is affected
- Jewish communities and households
- Observant students and workers
Owners Filled
Steward
Nobody owns the festival; Jewish communities and their religious authorities keep it.

- Which calendar authorities and rules should resolve duration, day boundaries and travel cases for each supported community?
- How should differing household and guest customs be represented when there is no single agreed food or seder standard?
- What evidence is sufficient to record completion of chametz-related actions without implying an independent religious ruling?
- How should health-related adaptations and exemptions be recorded while leaving medical and religious determinations with the relevant people?
