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

The class year_month represents a specific month of a specific year, but with an unspecified day. It is a field-based time point, with a resolution of std::chrono::months.

year_month is a TriviallyCopyable StandardLayoutType.

Member functions

(constructor)	constructs a year_month (public member function)
yearmonth	accesses the stored year and month (public member function)
operator+=operator-=	modifies the year_month by some number of months or years (public member function)
ok	checks if this year_month is valid (public member function)

Nonmember functions

operator==operator<=> (C++20)	compares two year_month values (function)
operator+operator- (C++20)	performs arithmetic on year_month (function)
operator<< (C++20)	outputs a year_month into a stream (function template)
from_stream (C++20)	parses a year_month from a stream according to the provided format (function template)

Helper classes

std::formatter<std::chrono::year_month> (C++20)	formatting support for year_month (class template specialization)
std::hash<std::chrono::year_month> (C++26)	hash support for std::chrono::year_month (class template specialization)
