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

The class year_month_day represents a specific year, month, and day. 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_day is a TriviallyCopyable StandardLayoutType.

Member functions

(constructor)	constructs a year_month_day (public member function)
operator+=operator-=	modifies the time point by some number of months or years (public member function)
yearmonthday	accesses the year, month, and day stored in this object (public member function)
operator sys_daysoperator local_days	converts to a std::chrono::time_point (public member function)
ok	checks if the year_month_day represents a valid date (public member function)

Nonmember functions

operator==operator!=operator<operator<=operator>operator>=	compares two year_month_day objects (function)
operator+operator-	adds or subtracts a year_month_day and some number of years or months (public member function)
operator<<	outputs a year_month_day into a stream (function template)
to_stream	outputs a year_month_day into a stream according to the provided format (function template)
from_stream	parses a year_month_day from a stream according to the provided format (function template)
