constexpr std::chrono::month month() const noexcept;	(1)	(since C++20)
constexpr std::chrono::weekday_indexed weekday_indexed() const noexcept;	(2)	(since C++20)

Retrieves a copy of the month and weekday_indexed objects stored in *this.

Return value

1) A copy of the std::chrono::month object stored in *this.

2) A copy of the std::chrono::weekday_indexed object stored in *this.

Example

Run this code

#include <chrono>
#include <iostream>
 
int main()
{
    std::cout << std::boolalpha;

    auto mwdi{std::chrono::March/std::chrono::Friday[1]}; // 1st Friday in a March
    std::cout << (std::chrono::year_month_day{mwdi/2024} == 
                  std::chrono::year_month_day{std::chrono::March/1/2024})
                  << ' ';
    auto index = mwdi.weekday_indexed().index();
    auto weekday = mwdi.weekday_indexed().weekday();
    mwdi = {mwdi.month(), weekday[index + 4]}; // 5th Friday in a March
    std::cout << (std::chrono::year_month_day{mwdi/2024} == 
                  std::chrono::year_month_day{std::chrono::March/29/2024})
                  << '\n';
}

Output:

true true
