template <class CharT, class Traits>

std::basic_ostream<CharT, Traits>&
operator<<(std::basic_ostream<CharT, Traits>& os,

           const std::chrono::year_month_weekday& ymwd);
(since C++20)

Outputs a textual representation of ymwd into os, as if by

os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{}/{}/{}"),
                  ymwd.year(), ymwd.month(), ymwdl.weekday_indexed());

where STATICALLY_WIDEN<CharT>("...") is "..." if CharT is char, and L"..." if CharT is wchar_t.

[edit] Return value

os.
