    "description": "The set of date and time-window definitions that schedules refer to. The reserved keys (holidays, business_holidays, business_days, workweek, business_hours) are the built-in definitions with layer-model semantics; 'date_sets' is the open namespace for user-defined named date sets, and its values are lists of date literals only. Wherever a date list is expected, a name may be written instead of the array: the name is either an entry of 'date_sets' or one the host binds to a resolver, and the two share one namespace. A calendar contains wall-clock dates and times only and defines no timezone of its own; its entries are written on the premise of the document-level timezone. This value carries rules JSON Schema cannot express; consult the specification.",
