Description
Determines the day of the week of a given date. The default for dayofweek is FirstDayOfWeek.Sunday.
To determine the day of the week, think of the day specified by
dayofweek
as day 1, and the value returned
by the function as indicating the day relative to day 1. Then, for
example, if the return value of WeekDay is 2,
this specifies the day following
dayofweek
. A return value of 1 specifies
dayofweek
. A return value of 7 specifies
the day before dayofweek
.

enumeration are:
