Defined in header <chrono>
class year_month_weekday;		(since C++20)

The class year_month_weekday represents the n-th weekday of a specific year and month. It is a field-based time point, with a resolution of std::chrono::days. std::chrono::years- and std::chrono::months-oriented arithmetic are supported directly. An implicit conversion to and from std::chrono::sys_days allows std::chrono::days-oriented arithmetic to be performed efficiently.

year_month_weekday is a TriviallyCopyable StandardLayoutType.

Member functions

(constructor)	constructs a year_month_weekday (public member function)
operator+=operator-=	modifies the time point by some number of months or years (public member function)
yearmonthweekdayindexweekday_indexed	accesses the fields of this object (public member function)
operator sys_daysoperator local_days	converts to a std::chrono::time_point (public member function)
ok	checks whether this object represents a valid date (public member function)

Nonmember functions

operator==operator!=	compares two year_month_weekday objects (function)
operator+operator-	adds or subtracts a year_month_weekday and some number of years or months (function)
operator<<	outputs a year_month_weekday into a stream (function template)
