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

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

The < , <= , > , >= , and != operators are synthesized from operator <=> and operator == respectively.

Return value

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

Example

Run this code 
#include <chrono>
 
int main()
{
    constexpr std::chrono::month m1{6}, m2{8};
 
    static_assert
    (
        m1 < m2 && m1 == m1 && m1 <= m2 &&
        m2 > m1 && m2 != m1 && m2 >= m1 &&
        m1 <=> m2 != 0
    );
}
