constexpr bool operator == ( const std:: chrono :: month_weekday & x,
const std:: chrono :: month_weekday & y ) noexcept ;

x. month ( ) == y. month ( ) && x. weekday_indexed ( ) == y. weekday_indexed ( )

示例

运行此代码 
#include <chrono>
int main()
{
    constexpr auto mwdi1{std::chrono::March/std::chrono::Friday[1]};
    constexpr auto mwdi2
    {
        std::chrono::month_weekday
        {
            std::chrono::month(3), std::chrono::weekday(5)[1]
        }
    };
    static_assert(mwdi1 == mwdi2);
}
