[edit]

Defined in header`<chrono>`
constexprbool operator==(conststd::chrono::year& x, conststd::chrono::year& y)noexcept;	(1)	(since C++20)
constexprstd::strong_ordering operator<=>(conststd::chrono::year& x, conststd::chrono::year& y)noexcept;	(2)	(since C++20)

Compare the twostd::chrono::yearx andy.

The<,<=,>,>=, and!= operators aresynthesized fromoperator<=> andoperator== 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(){usingnamespace 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
