If omitted, defaults to the value specified in the calendar table template for the current user, if present; otherwise, defaults to 12. Return Value: Returns a table with a single column named "Date" that contains a contiguous set of dates. The range is calculated automatically based on data in the model. The date range returned is dates between the beginning of the fiscal year associated with MinDate and the end of the fiscal year associated with MaxDate. Example: In this example, the MinDate and MaxDate in the data model are July 1, 2010 and June 30, 2011. CALENDARAUTO() will return all dates between January 1, 2010 and December 31, 2011. CALENDARAUTO(3) will return all dates between March 1, 2010 and February 28, 2012.
