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/
.
