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

The class day represents a day in a month. Its normal range is [1, 31], but it may hold any number in [0, 255].

day is a TriviallyCopyable StandardLayoutType.

Member functions

(constructor)	constructs a day (public member function)
operator++operator++(int)operator--operator--(int)	increments or decrements the day (public member function)
operator+=operator-=	adds or subtracts a number of days (public member function)
operator unsigned	retrieves the stored day value (public member function)
ok	checks if the stored day value is in the normal range (public member function)

Nonmember functions

operator==operator!=operator<operator<=operator>operator>=	compares two day objects (function)
operator+operator-	adds or subtracts a number of days and a day, or find the difference between two days (function)
operator<<	outputs a day into a stream (function template)
to_stream	outputs a day into a stream according to the provided format (function template)
from_stream	parses a day from a stream according to the provided format (function template)

Literals

Defined in inline namespace std::literals::chrono_literals
operator""d (C++20)	A std::chrono::day literal representing a day of a month (function)
