Public Holiday Specification Class

[tinohager]

A proposal for discussion

The goal is to better display the moved holidays and also to minimize if statements in the code.

var weekendObservedRuleSet = new ObservedRuleSet
{
	Saturday = date => date.AddDays(-1),
	Sunday = date => date.AddDays(1),
};

var specifications = new PublicHolidaySpecification[]
{
	new PublicHolidaySpecification
	{
		Date = new DateTime(year, 12, 25),
		EnglishName = "New Year's Day",
		LocalName = "New Year's Day",
		ObservedRuleSet = weekendObservedRuleSet
	},
	new PublicHolidaySpecification
	{
		Date = thirdMondayInJanuary,
		EnglishName = "Martin Luther King, Jr. Day",
		LocalName = "Martin Luther King, Jr. Day",
	},
	new PublicHolidaySpecification
	{
		Date = thirdMondayInFebruary,
		EnglishName = "Washington's Birthday",
		LocalName = "Presidents Day",
	},
	new PublicHolidaySpecification
	{
		Date = lastMondayInMay,
		EnglishName = "Memorial Dayay",
		LocalName = "Memorial Day",
	},
	new PublicHolidaySpecification
	{
		Date = new DateTime(year, 12, 25),
		EnglishName = "Christmas Day",
		LocalName = "Christmas Day",
		ObservedRuleSet = weekendObservedRuleSet
	}
};

var specificationProcessor = new PublicHolidaySpecificationProcessor();
var items = specificationProcessor.Process(specifications, countryCode);
