Gets or sets the month on which the appointment occurs.
A positive integer value that specifies the month number.
If the recurrence pattern is defined on a yearly time basis (the IRecurrenceInfo.Type property is set to the RecurrenceType.Yearly value), the Month property specifies the number of the month on which the corresponding appointment reoccurs. The effective values for this property are 1 to 12 inclusive, which identify the months from January to December. For instance, setting the Month property to 10 specifies October.
