Extract Day of Week from Date

Assuming you're needing this in a process. You can use the following to get the day of the week in a process formula: 

[#MyDateFieldHere#].DayOfWeek

You can use that value as a string, like this: 

[#MyDateFieldHere#].DayOfWeek.ToString() == "Monday"

Or using the numeric values for the days (see values here)

[#MyDateFieldHere#].DayOfWeek == 1

For example, to check if the date is a weekday (not sat and not sun)

[#MyDateFieldHere#].DayOfWeek.ToString() != "Saturday" && [#MyDateFieldHere#].DayOfWeek.ToString() != "Sunday"
