std::chrono::year
Member functions
Nonmember functions
operator==operator<=>
Helper classes
(C++26)
Defined in header
<chrono>
constexpr bool operator==( const std::chrono::year & x,
const std::chrono::year & y ) noexcept;
(1)
(since C++20)
const std::chrono::year & y ) noexcept;
constexpr std::strong_ordering operator<=>( const std::chrono::year & x,
const std::chrono::year & y ) noexcept;
(2)
(since C++20)
const std::chrono::year & y ) noexcept;
Compare the two std::chrono::year x and y.
The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.
[edit] Return value
1) int(x) == int(y)
2) int(x) <=> int(y)
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { using namespace std::chrono; constexpr year y1{2020}; constexpr year y2{2021}; std::cout << std::boolalpha << (y1 != y2) << '\n'; static_assert((2020y < 2023y) && (2020y == 2020y) && (2020y <= 2023y) && (2023y > 2020y) && (2023y != 2020y) && (2023y >= 2020y)); }
Output:
true
