std::chrono::year_month_weekday_last
Defined in header <chrono>
class year_month_weekday_last ;
(since C++20)

The class year_month_weekday_last represents the last weekday of a specific year and month. It is a field-based time point, with a resolution of std::chrono::days , except that it is limited to pointing to the last weekday of a year and month. std::chrono::years - and std::chrono::months -oriented arithmetic are supported directly. An implicit conversion to std::chrono::sys_days allows std::chrono::days -oriented arithmetic to be performed efficiently.

year_month_weekday_last is a TriviallyCopyable StandardLayoutType .
