formatter<std::chrono::month_day>

hash<std::chrono::month_day> (C++26)

 

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

Constructs a month_day.

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

2) Constructs a month_day that stores the month m and the day d.

Notes

A more convenient way to construct a month_day is with operator/, e.g., std::chrono::April/1.

Example

Run this code

#include <chrono>
#include <iostream>
 
int main()
{
    using namespace std::chrono_literals;
    constexpr auto 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';
}

Output:

29/2
