      Compare the twostd::chrono::weekdayx andy.

      The!= operator issynthesized fromoperator==.

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

      [edit]Notes

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

      [edit]Example

      Run this code
      #include <chrono> int main(){usingnamespace std::literals; constexprstd::chrono::weekday wd1{2};constexprstd::chrono::weekday wd2{std::chrono::Friday};    static_assert(wd1!= wd2); // 13 January 1313 is a Fridayconstexprstd::chrono::weekday wd3{1313y/1/13d};    static_assert(wd2== wd3);}
