Can Calendar.GetDayOfWeek () return (DayOfWeek) 7?

I look through the code and found this bit (rewritten):

if ((int)CultureInfo.CurrentCulture.Calendar.GetDayOfWeek(someDate) == 7) ...

I would think that this condition always returns false, because DayOfWeek (return type) is in the range from 0 to 6, or can it return 7 in a certain culture?

Normally GetDayOfWeek will never return the (converted) value of 7.

From the code it is very unclear what the programmer wants. I suggest rewriting it as:

if (CultureInfo.CurrentCulture.Calendar.GetDayOfWeek(someDate) == DayOfWeek.Saturday) ...

Or something.
