std::chrono::month_day
Member functions
Nonmember functions
operator==operator<=>
Helper classes
(C++26)
Defined in header
<chrono>
constexpr bool operator==( const std::chrono::month_day & x,
const std::chrono::month_day & y ) noexcept;
(1)
(since C++20)
const std::chrono::month_day & y ) noexcept;
constexpr std::strong_ordering operator<=>( const std::chrono::month_day & x,
const std::chrono::month_day & y ) noexcept;
(2)
(since C++20)
const std::chrono::month_day & y ) noexcept;
Compares two month_day values.
The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.
[edit] Return value
1) x.month() == y.month() && x.day() == y.day()
2) x.month() <=> y.month() != 0 ? x.month() <=> y.month() : x.day() <=> y.day()
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { constexpr auto md1{std::chrono::August /15}; constexpr auto md2{std::chrono::month (8)/std::chrono::day (15)}; std::cout << std::boolalpha << (md1 == md2) << '\n'; static_assert(md1 <= md2); }
Output:
true
