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

The class year_month_day_last represents the last day of a specific year and month. It is a field-based time point, with a resolution of std::chrono::days, subject to the limit that it can only represent the last day of a 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_day_last is a TriviallyCopyable StandardLayoutType.
