formatter<std::chrono::day>

 

constexpr bool operator==( const std::chrono::day& x,                            const std::chrono::day& y ) noexcept;	(1)	(since C++20)
constexpr std::strong_ordering operator<=>( const std::chrono::day& x,                                             const std::chrono::day& y ) noexcept;	(2)	(since C++20)

Compare the two std::chrono::day x and y.

Return value

1) unsigned(x) == unsigned(y)

2) unsigned(x) <=> unsigned(y)
