(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; |

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/
.
