예제

#include <chrono>
#include <iostream>
using namespace std::chrono;
int main()
{
    auto ymwdl{Tuesday[last]/November/2022};
    auto wdl = ymwdl.weekday_last();
    wdl = (wdl.weekday() + days(1))[last];
    ymwdl = {ymwdl.year() + years(1), ymwdl.month() - months(2), wdl};
    std::cout << year_month_day(ymwdl) << '\n';
}
