std::chrono::year_month_weekday
 
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 << ymwd.year() << '/' << ymwd.month() << '/' << ymwdl.weekday_indexed();

Return value

os.

Notes

This operator<< is primarily intended for debugging use. When used with non-default stream flags, the output may be surprising: 

using namespace std::chrono;
auto ymwd = 2001y/2/Tuesday[1];
std::cout.width(10);
std::cout.fill('-');
std::cout << std::left << ymwd; // may output "2001------/Feb/Tue[1]"
