Example¶

// Run this code

#include <cassert>
#include <chrono>

int main()
{
constexpr auto ym{std::chrono::year(2021)/std::chrono::January};
constexpr auto wdi{std::chrono::Wednesday[1]};
auto ymwdi{ym/wdi};
const auto index{ymwdi.index() + 1};
auto weekday{ymwdi.weekday() + std::chrono::days(1)};
ymwdi = {ymwdi.year()/ymwdi.month()/weekday[index]};
// Second Thursday in January, 2021
assert(std::chrono::year_month_day{ymwdi} == std::chrono::January/14/2021);
}
