Specifies the interval between occurrences of the recurrence. The interval field works in conjunction with the "recurrenceType" field to determine the cycle of the recurrence. The maximum allowable value is 99 for weekly patterns and 999 for daily patterns. The default value is 1. For example, if the recurrenceType is set to daily, and the "interval" is set to 3, the recurrence will occur every third day.
