Retrieves the field values stored in this year_month_weekday object.

Return values

1) Returns the stored std::chrono::year value.
2) Returns the stored std::chrono::month value.
3) Returns the stored std::chrono::weekday value.

Example

// Run this code

#include <iostream>
#include <chrono>

int main()
{
std::cout << std::boolalpha;

constexpr auto ym {std::chrono::year(2021)/std::chrono::January};
constexpr auto wdi {std::chrono::Wednesday[1]};
auto ymwdi {ym/wdi};
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
std::cout << (std::chrono::year_month_day{ymwdi} ==
std::chrono::January/14/2021) << '\n';
}

Output:

true
