std::chrono::operator==(std::chrono::year_month_weekday)(3)

NAME
std::chrono::operator==(std::chrono::year_month_weekday) - std::chrono::operator==(std::chrono::year_month_weekday)

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