const std::chrono::weekday_indexed& wdi) noexcept;

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/.
