NAME¶

std::chrono::year_month_weekday_last - std::chrono::year_month_weekday_last

Synopsis¶

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.

Member functions¶

constructor constructs a year_month_weekday_last
(public member function)
operator+= modifies the time point by some number of months or years
operator-= (public member function)
year
month accesses the fields of this object
weekday (public member function)
weekday_last
operator sys_days converts to a std::chrono::time_point
operator local_days (public member function)
ok checks whether this object represents a valid date
(public member function)

Nonmember functions

operator== compares two year_month_weekday_last values
(C++20) (function)
operator+ adds or subtracts a year_month_weekday_last and some number of years or
operator- months
(C++20) (function)
operator<< outputs a year_month_weekday_last into a stream
(C++20) (function template)

Helper classes¶

std::formatter that formats a
std::formatter<std::chrono::year_month_weekday_last> year_month_weekday_last
(C++20) according to the provided
format
