Description
Returns the day of the week for a specified date.
DayOfWeek returns the day of the week of the specified date as an integer between 1 and 7, where Sunday is the first day of the week and Saturday is the seventh.
Note: DayOfWeek is not compliant with the ISO 8601 standard, which defines Monday as the first day of the week. For an ISO 8601 compliant version, use the DayOfTheWeek function instead.
