# std::chrono::operator==(std::chrono::weekday)

From cppreference.com
< cpp‎ | chrono‎ | weekday

Defined in header `<chrono>` |  |
constexpr bool operator==( const std::chrono::weekday & x, const std::chrono::weekday & y ) noexcept; |  | (since C++20)

Compare the two std::chrono::weekday x and y.

The `!=` operator is synthesized from `operator==`.

### Return value

x.c_encoding() == y.c_encoding()

### Notes

`weekday` does not support the `<`, `<=`, `>` and `>=` operators because there is no universal consensus on which day is the first day of the week.

### Example

Run this code

    #include <chrono>

    int main()
    {
        using namespace std::literals;

        constexpr std::chrono::weekday wd1{2};
        constexpr std::chrono::weekday wd2{std::chrono::Friday};
        static_assert(wd1 != wd2);

        // 13 January 1313 is a Friday
        constexpr std::chrono::weekday wd3{1313y/1/13d};
        static_assert(wd2 == wd3);
    }
