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

The class year represents a year in the proleptic Gregorian calendar. Its range is [-32767, 32767].

year is a TriviallyCopyable StandardLayoutType.

Member functions

(constructor)	constructs a year (public member function)
operator++operator++(int)operator--operator--(int)	increments or decrements the year (public member function)
operator+=operator-=	adds or subtracts a number of years from a year (public member function)
operator+operator-	applies unary operators to year (public member function)
is_leap	determines if the year is a leap year (public member function)
operator int	retrieve the year value (public member function)
ok	checks if the stored year value is valid (public member function)
min [static]	returns the smallest possible year value (public static member function)
max [static]	returns the largest possible year (public static member function)

Non-member functions

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

Helper classes

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

Literals

Defined in inline namespace std::literals::chrono_literals
operator""y (C++20)	a std::chrono::year literal representing a particular year (function)
