Defined in header <chrono>
constexpr bool operator == ( const std:: chrono :: year_month_weekday & x,
const std:: chrono :: year_month_weekday & y ) noexcept ;
(since C++20)

Compares the two year_month_weekday values x and y .

The != operator is synthesized from operator== .

Return value

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

Example

#include <chrono>
#include <iostream>
using namespace std::chrono;
 
int main()
{
    constexpr auto ymwdi1{Wednesday[1]/January/2021};
    constexpr year_month_weekday ymwdi2{year(2021), month(1), weekday(3)[1]};
    std::cout << std::boolalpha << (ymwdi1 == ymwdi2) << '\n';
}

Output:

true
