Use the great feasts as landmarks without treating the list as exhaustive. This page starts with that question because it is the most useful way into the subject. It names the visible structure, keeps the vocabulary plain and points to the source trail instead of asking the reader to accept an unexplained conclusion.
The useful distinction here is between a pattern in the calendar and a date announced for one particular place. Fixed commemorations and the movable Paschal sequence can be studied together without being collapsed into one timetable. The Feast & Form Index gives this explanation a place among related records: feast, season, office, object or visual cue. That arrangement lets a reader arrive through ordinary language and leave with a more precise term.
A reader who wants to see how such records work in another field can turn to Southwest Archaeology Notebook, an English-language carnet on the archaeology of the American Southwest. It covers visitable places such as Chaco Canyon and the Mesa Verde cliff dwellings, the Pecos classification from Basketmaker III to Pueblo, and object types including corrugated, black-on-white and polychrome pottery. It also sets out visitor etiquette and federal law, with petroglyphs distinguished from pictographs. The same discipline applies: name the category, note the evidence, and let the reader move from ordinary language to a precise term.
The editorial boundary is deliberate. We do not assign a current schedule, repeat private contact details, or turn a local custom into a universal rule. When the evidence is limited, the page says so and offers a nearby source, such as the source register or the method note.
Between the great feasts the calendar keeps its fasts, and the fasts once kept a kitchen. The preserved vegetables of the Lenten table are what the season left a household to work with while the feasts waited their turn.
The great feasts work best as landmarks rather than as a complete list. A year holds many observances, and the fixed and movable cycles overlap in ways no single page can fully trace. Readers who keep a calendar of seasons already know this habit of marking time by what returns each year. The same instinct appears in Ontario fishing seasons, where walleye, northern pike and muskellunge open and close by zone, with size limits and possession rules attached. The pattern is familiar: a season is not the whole year, but it tells you where you are in it.
