That program better be using an existing date library, because otherwise it’s most definitely wrong.
public string GetDayOfWeek(DateTime date) => "saturday";
I also calculated it, his result checks out.
Don’t be ridiculous, that would never pass QA.
But this one will. Joy for years to come:
public string GetDayOfWeek(DateTime date) {
return ((date - new DateTime(1970, 1, 1)).Milliseconds / 86400000) % 7 switch {
0 => "Thursday",
1 => "Friday",
2 => "Saturday",
3 => "Sunday",
4 => "Monday"
};
}
Bro probably to account for leap Thursday’s. We have one every ~28k years to keep in alignment with the true solar week.
