5]
. Otherwise false.
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { std::cout << std::boolalpha; std::chrono::weekday_indexed wdi{std::chrono::Tuesday[2]}; std::cout << (wdi.ok()) << ' '; wdi = {std::chrono::weekday(42)[2]}; std::cout << (wdi.ok()) << ' '; wdi = {std::chrono::Tuesday[-4]}; std::cout << (wdi.ok()) << '\n'; }
Output:
true false false
