hash<std::chrono::year> (C++26)

 

constexpr explicit operator int() const noexcept;		(since C++20)

Returns the year value stored in *this.

Return value

The year value stored in *this.

Example

Run this code

#include <chrono>
#include <iostream>
using namespace std::chrono;
 
int main()
{
    constexpr std::chrono::year y{2020};
    std::cout << "The year is: " << static_cast<int>(y) << '\n';
 
    const year_month_day ymd{floor<days>(system_clock::now())};
    const std::chrono::year this_year{ymd.year()};
    std::cout << "This year is: " << int(this_year) << '\n';
}

Possible output:

The year is: 2020
This year is: 2023
