In the case where the Interval property is set to a value greater than one, it might be necessary to synchronize the beginning of the cycles generated by this instance with a particular day, day of the week, or month. For example, if a DateInterval is intended to represent a two-week pay period, the developer might need to define the beginning of the pay cycle as the first monday of the current year. The SynchronizingDate property makes it possible to define the synchronization point for the cycle in this manner. The Interval property in this case would be set to 2, the IntervalUnits property would be set to 'Weeks', and the SynchronizingDate property would be set to the first Monday of the current year.
Not all of the components of the SynchronizingDate structure are necessarily used; which ones are used depends on the value of the IntervalUnits property. For example, when IntervalUnits is set to 'Monthly', only the Month component of the date is used; when set to 'Weekly', only the DayOfWeek component is used.
When no value has been explicitly assigned to the SynchronizingDate property, the value of the associated UltraCalendarInfo's MinDate property is used to define the synchronizing date for the cycle.
