	Label              string
	AccessibilityLabel string
	Value              string
	Hint               string
	Selected           bool
	RangeStart         bool
	RangeMiddle        bool
	RangeEnd           bool

	Disabled           bool
}

CalendarDay is one application-owned cell in display order. Label is the visible day text; AccessibilityLabel should contain the complete localized date when Label alone would be ambiguous. Date arithmetic and selection changes remain application responsibilities.
