NAME¶

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

Synopsis¶

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

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 <iostream>
#include <chrono>

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

constexpr std::chrono::weekday wd1{2};
constexpr std::chrono::weekday wd2{std::chrono::Friday};
// 1 January 2021 is a Friday
constexpr std::chrono::weekday wd3{2021y/1/1};

std::cout << std::boolalpha;
std::cout << (wd1 == wd2) << "\n";
std::cout << (wd2 == wd3) << "\n";
}

Output:¶

false
true
