[`static func date(Date, kind: RelevantContext.DateKind) -> RelevantContext`](/documentation/RelevanceKit/RelevantContext/date(_:kind:)) Tells the system a widget is relevant at a specific date and provides an additional contextual hint. [`static func date(interval: DateInterval, kind: RelevantContext.DateKind) -> RelevantContext`](/documentation/RelevanceKit/RelevantContext/date(interval:kind:)) Tells the system a widget is relevant for a time interval and provides an additional contextual hint. [`static func date(range: ClosedRange, kind: RelevantContext.DateKind) -> RelevantContext`](/documentation/RelevanceKit/RelevantContext/date(range:kind:)) Tells the system a widget is relevant for a known date range and provides an additional contextual hint. [`struct DateKind`](/documentation/RelevanceKit/RelevantContext/DateKind) Values the system uses as additional context for time-based relevance clues.
