NAME
       std::chrono::weekday - std::chrono::weekday

Synopsis
	  Defined in header <chrono>
	  class	weekday;				       (since C++20)
	  inline constexpr std::chrono::weekday	Sunday{0};     (since C++20)
	  inline constexpr std::chrono::weekday	Monday{1};     (since C++20)
	  inline constexpr std::chrono::weekday	Tuesday{2};    (since C++20)
	  inline constexpr std::chrono::weekday	Wednesday{3};  (since C++20)
	  inline constexpr std::chrono::weekday	Thursday{4};   (since C++20)
	  inline constexpr std::chrono::weekday	Friday{5};     (since C++20)
	  inline constexpr std::chrono::weekday	Saturday{6};   (since C++20)

	  The  class weekday represent a day of	the week in the	proleptic Gre-
       gorian calendar.
	  Its normal range is [0, 6], for Sunday through Saturday, but it  can
       hold any	value
	  in  the  range [0, 255]. Seven named constants are predefined	in the
       std::chrono
	  namespace for	the seven days of the week.

	  weekday is a TriviallyCopyable StandardLayoutType.

Member functions
	  constructor	  constructs a weekday
			  (public member function)
	  operator++
	  operator++(int) increments or	decrements the weekday
	  operator--	  (public member function)
	  operator--(int)
	  operator+=	  adds or subtracts a number of	days
	  operator-=	  (public member function)
	  c_encoding	  retrieves the	stored weekday value
	  iso_encoding	  retrieves ISO	8601 weekday value
			  (public member function)
	  ok		  checks if the	stored weekday value is	valid
			  (public member function)
			  convenience syntax for  constructing	a  weekday_in-

			  (public member function)

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

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

Example
       // Run this code

	#include <chrono>
	#include <iostream>

	int main()
	{
	    std::chrono::weekday x{42 /	13};
	    std::cout << x++ <<	'\n';
	    std::cout << x << '\n';
	    std::cout << ++x <<	'\n';
	}
