[time.cal.mwd]

month_weekday represents the

{n th weekday of a month, of an as yet unspecified year .}^{th weekday of a month, of an as yet unspecified year .}

To do this the month_weekday stores a month and a weekday_indexed.

[Example 1: constexpr auto mwd = February/Tuesday[3]; / mwd is the third Tuesday of February of an as yet unspecified year static_assert(mwd.month() == February); static_assert(mwd.weekday_indexed() == Tuesday[3]); — end example]

month_weekday is a trivially copyable and standard-layout class type.

30.8.11.2 Member functions [time.cal.mwd.members]

🔗

constexpr month_weekday(const chrono::month& m, const chrono::weekday_indexed& wdi) noexcept;

Effects: Initializes m_ with m, and wdi_ with wdi.

🔗

constexpr chrono::month month() const noexcept;

Returns: m_.

🔗

constexpr chrono::weekday_indexed weekday_indexed() const noexcept;

Returns: wdi_.

🔗

constexpr bool ok() const noexcept;

Returns: m_.ok() && wdi_.ok().

30.8.11.3 Non-member functions [time.cal.mwd.nonmembers]

🔗

constexpr bool operator=(const month_weekday& x, const month_weekday& y) noexcept;

Returns: x.month() == y.month() && x.weekday_indexed() == y.weekday_indexed().

🔗

template<class charT, class traits>
  basic_ostream<charT, traits>&
    operator<(basic_ostream<charT, traits>& os, const month_weekday& mwd);

Effects: Equivalent to: return os << format(os.getloc(), STATICALLY-WIDEN<charT>("{:L}/{:L}"), mwd.month(), mwd.weekday_indexed();
