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

Compares the two year_month_weekday_last values x and y .

The != operator is synthesized from operator== .

Return value

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

Example

#include <chrono>
#include <iostream>
using namespace std::chrono;
 
int main()
{
    constexpr auto ymwdl1{Tuesday[last]/11/2021};
    auto ymwdl2 = Tuesday[last]/11/2020;
    ymwdl2 += months(12);
    std::cout << std::boolalpha << (ymwdl1 == ymwdl2) << '\n';
}

Output:

true
