std::chrono::year_month_weekday
year_month_weekday ( ) = default ;
(1) (since C++20)
constexpr year_month_weekday ( const std:: chrono :: year & y,

const std:: chrono :: month & m,

const std:: chrono :: weekday_indexed & wdi ) noexcept ;
(2) (since C++20)
constexpr year_month_weekday ( const std:: chrono :: sys_days & dp ) noexcept ;
(3) (since C++20)
constexpr explicit year_month_weekday ( const std:: chrono :: local_days & dp ) noexcept ;
(4) (since C++20)

Constructs a year_month_weekday object.

1) Default constructor leaves the fields uninitialized.
2) Constructs a year_month_weekday object storing the year y , the month m , the weekday wdi. weekday ( ) and the weekday index wdi. index ( ) .
3) Constructs a year_month_weekday object corresponding to the date represented by dp . For any year_month_weekday object storing a valid date, converting it to sys_days and back yields the same value. This constructor defines an implicit conversion from sys_days to year_month_weekday .
4) Constructs a year_month_weekday object corresponding to the date represented by dp . Equivalent to year_month_weekday ( sys_days ( dp. time_since_epoch ( ) ) ) .

Notes

A year_month_weekday can also be created by combining one of the partial-date types std::chrono::year_month and std::chrono::month_weekday with the missing component (indexed weekday and year, respectively) using operator/ .
