(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
Run this code
#include <iostream> #include <chrono> 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
