DayOfWeek("date")

The ordinal for the day of the week, as an integer in the range 1 (Sunday) to 7 (Saturday).

When passing a date/time object as a string, enclose it in quotation marks. Otherwise, it is interpreted as a numeric representation of a date/time object.
Note: You can pass the CreateDate function or Now function as the date parameter of this function; for example, #DayOfWeek(CreateDate(2001, 3, 3))#
