chrono I/O
(C++20)
C-style date and time
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

#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);
}
