constexpr bool operator==(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (1) | (since C++20)
constexpr bool operator!=(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (2) | (since C++20)
constexpr bool operator<(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (3) | (since C++20)
constexpr bool operator>(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (4) | (since C++20)
constexpr bool operator<=(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (5) | (since C++20)
constexpr bool operator>=(const std::chrono::month_day & x, const std::chrono::month_day & y) noexcept; | (6) | (since C++20)

Compares two `month_day` objects.

### Return value

1) x.month() == y.month() && x.day() == y.day()
2) !(x == y).
3) x.month() < y.month() || (x.month() == y.month() && x.day() < y.day())
4) y < x
5) !(y < x)
6) !(x < y)
