| constexpr bool operator==( const std::chrono::month_weekday_last& x,  const std::chrono::month_weekday_last& y ) noexcept; | (since C++20) | |
Compares the two month_weekday_last values x and y.
The != operator is synthesized from  operator==.
Return value
x.month() == y.month() && x.weekday_last() == y.weekday_last().
Example
Run this code
#include <chrono> int main() { constexpr std::chrono::month_weekday_last mwdl1 { std::chrono::March/std::chrono::Friday[std::chrono::last] }; constexpr std::chrono::month_weekday_last mwdl2 { std::chrono::March, std::chrono::Friday[std::chrono::last] }; static_assert(mwdl1 == mwdl2); }
