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 <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);
}
