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)
explicit constexpr 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())).

[edit] 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/.
