month_day()=default;	(1)	(since C++20)
constexpr month_day(conststd::chrono::month& m, conststd::chrono::day& d)noexcept;	(2)	(since C++20)

Constructs amonth_day.

1) Default constructor leaves the stored month and day values uninitialized.

2) Constructs amonth_day that stores the monthm and the dayd.

[edit]Notes

A more convenient way to construct amonth_day is withoperator/, e.g.,std::chrono::April/1.

[edit]Example

Run this code

#include <chrono>#include <iostream> int main(){usingnamespace std::chrono_literals;constexprauto mo_da=std::chrono::month_day(std::chrono::February, 29d);std::cout<<static_cast<unsigned>(mo_da.day())<<'/'<<static_cast<unsigned>(mo_da.month())<<'\n';}
