Defined in header
<chrono>
template< class CharT, class Traits >
(since C++20)
std::basic_ostream <CharT, Traits>&
operator<<( std::basic_ostream <CharT, Traits>& os,
Outputs a textual representation of mwdl into os, as if by
os << std::format (os.getloc(), STATICALLY_WIDEN<CharT>("{:L}/{:L}"),
mwdl.month(), mwdl.weekday_last());
where STATICALLY_WIDEN<CharT>("{:L}/{:L}") is "{:L}/{:L}" if CharT is char, and L"{:L}/{:L}" if CharT is wchar_t.
