   apt.RecurrenceInfo.Month = 2;
   apt.RecurrenceInfo.WeekOfMonth = WeekOfMonth.None;
   apt.RecurrenceInfo.DayNumber = 7;
   apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount;
   apt.RecurrenceInfo.OccurrenceCount = 4;
   

   VB.NET

   apt.RecurrenceInfo.Type = RecurrenceType.Yearly
   apt.RecurrenceInfo.Periodicity = 1
   apt.RecurrenceInfo.Start = apt.Start
   apt.RecurrenceInfo.Month = 2
   apt.RecurrenceInfo.WeekOfMonth = WeekOfMonth.None
   apt.RecurrenceInfo.DayNumber = 7
   apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount

   apt.RecurrenceInfo.Month = 8;
   apt.RecurrenceInfo.WeekOfMonth = WeekOfMonth.Second;
   apt.RecurrenceInfo.WeekDays = WeekDays.Monday;
   apt.RecurrenceInfo.Range = RecurrenceRange.NoEndDate;
   

   VB.NET

   apt.RecurrenceInfo.Type = RecurrenceType.Yearly
   apt.RecurrenceInfo.Periodicity = 2
   apt.RecurrenceInfo.Start = apt.Start
   apt.RecurrenceInfo.Month = 8
