Field Value


When you call date-related functions, you can use the following enumeration members in your code in place of the actual values.

Some date-related functions take a DayOfWeek argument, a WeekOfYear argument, or both. The FirstWeekOfYear enumeration specifies the valid values for the WeekOfYear arguments, as well as the possible return values from the functions.

The WeekOfYear argument takes the FirstWeekOfYear enumeration members.
