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

比较二个 month_day 对象。

返回值

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)
