formatter<std::chrono::month_day>
hash<std::chrono::month_day> (C++26)

Defined in header`<chrono>`
template<class CharT,class Traits> std::basic_ostream<CharT, Traits>& operator<<(std::basic_ostream<CharT, Traits>& os,conststd::chrono::month_day& md);		(since C++20)

Outputs a textual representation ofmd into the streamos, as if by

os<<std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{:L}/{}"), md.month(), md.day())

whereSTATICALLY_WIDEN<CharT>("{:L}/{}") is"{:L}/{}" ifCharT ischar, andL"{:L}/{}" ifCharT iswchar_t.

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
P2372R3	C++20	the given locale was used by default	`L` is needed to use the given locale

format (C++20)	stores formatted representation of the arguments in a new string (function template)[edit]
std::formatter<std::chrono::month_day> (C++20)	formatting support for`month_day` (class template specialization)[edit]
