constexpr bool operator==(const std::chrono::weekday& x, const std::chrono::weekday& y) noexcept;
(since C++20)
constexpr bool operator!=(const std::chrono::weekday& x, const std::chrono::weekday& y) noexcept;
(since C++20)

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

Return value

1) unsigned(x) == unsigned(y)
2) unsigned(x) != unsigned(y)

Notes

weekday does not support the <, <=, > and >= operators because there is no universal consensus on which day is the first day of the week.
