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

Compares the two month_day_last values x and y.

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

[edit] Return value

1) x.month() == y.month()
2) x.month() <=> y.month()

[edit] Example

#include <iostream>
#include <chrono>
 
int main()
{
    constexpr auto mdl1 {std::chrono::February/std::chrono::last};
    constexpr std::chrono::month_day_last mdl2 {std::chrono::month(2)};
    std::cout << std::boolalpha << (mdl1 == mdl2) << '\n';
 
    static_assert(mdl1 <= mdl2);
}

Output:

true
