NAME¶

std::chrono::year_month_weekday - std::chrono::year_month_weekday

Synopsis¶

Defined in header <chrono>
class year_month_weekday; (since C++20)

The class year_month_weekday represents the n-th weekday of a specific year and
month. It is a field-based time point, with a resolution of std::chrono::days.
std::chrono::years- and std::chrono::months-oriented arithmetic are supported
directly. An implicit conversion to and from std::chrono::sys_days allows
std::chrono::days-oriented arithmetic to be performed efficiently.

year_month_weekday is a TriviallyCopyable StandardLayoutType.
